| Measuring Lens Centering, Air Spacing, and Center Thickness inside of Assembled IR Optical Systems
OptiCentric® 3D IR provides an ideal solution for the complete optomechanical characterization of assembled IR optical systems. The instrument integrates different lens analysis technologies and provides a valuable tool for the evaluation of complex optical systems in R&D or/and quality control in production environments.
The two-in-one solution for the detailed investigation of assembled objective lenses combines the OptiCentric® centering error measurement technology with the low coherence interferometer OptiSurf®, which characterizes the air gaps between lens surfaces and the center thicknesses of lenses within the assembled optical system. The combination of both technologies gives rise to a significantly increased overall measurement accuracy and therefore more detailed information for e.g. quality control during manufacturing. Typical accuracy of the system is
• Centering errors <0.1 µm
• Air spacing and center thickness <1 µm
OptiCentric® 3D in Operation
1. The OptiCentric® system determines the centering error (tilt and shift in x-y direction) of the elements of the optical system with respect to a reference axis.
2. The optical assembly under test is then aligned with the help of a tilt/translation stage or other adjusting elements to the measuring axis of the low coherence interferometer OptiSurf®. The highly accurate alignment enables the low coherence interferometer to precisely determine the position of the center of curvatures in z-direction, the air gaps between lenses and their respective center thicknesses.
3. After the center thicknesses and air gaps measurement is completed, the data are transferred to the MultiLens Software and the design data of the optical system is replaced by the actual geometry data measured with OptiSurf®.
4. As a result, the accuracy of the centering error data for each component of the optical system, measured initially with OptiCentric®, is significantly increased. |

| TriAngle® 3D - Autocollimator measuring angles along three axes: PITCH, YAW AND ROLL ANGLES
For the first time an Autocollimator can measure angles along three axes. A proprietary reticle and designed reflector combined with sophisticated software enables the measurement not only of the two classical tilt angles (pitch and yaw) but of the roll angle (rotation around autocollimator axis) as well. |
| WaveSensor® - Comprehensive Wavefront Measurement Using Shack-Hartmann Sensors
Aspheric lenses are of increasing importance in today’s optical industry. In a multitude of different areas of application aspheric lenses are used to build compact imaging systems. All of these have to be checked not only for the imaging properties of the final lens system but also for the quality of the intermediate products during assembly as well as the single lenses itself.
In most of the cases conventional methods cannot be used for this kind of testing. Although e.g. the measurement of the modulation transfer function is a well established method for fast and accurate quality inspection of entire objectives, it has its limitation for non imaging systems.
In contrast to this, Shack-Hartmann sensors are able to measure a very broad range of spherical and aspherical lenses as well as partially or fully assembled objectives due to their large dynamic range. In addition the high measurement frequency allows for real time testing and analysis.
Real Time Wavefront Sensors and Turnkey Solutions
With the WaveSensor® series a variety of Shack-Hartmann wavefront sensors optimized for different measurement applications is available. The WaveSensor® is integrated into existing laboratory or production setups or used for in-field testing. An additional module which is attached easily to the WaveSensor® allows for the measurement of surface form in reflection.
The WaveMaster® instruments are ShackHartmann based turnkey solutions for quality assurance, research and development, and production environments. They are employed for example in laboratories, institutes or mobile phone industry.
WaveSensor® Reflex Module
As a supplement of the WaveSensor® TRIOPTICS developed the reflex module which expands the applications of WaveSensor® to 3D- topography measurement. The module consists of an illumination unit with collimated light source and beam splitter and an objective tube. The measurement is either done with a collimated beam using the illumination unit only or with a focused beam using the illumination unit and an additional objective lens. The collimated illumination is employed to measure the surface and the angle of plane optics. Non planar surfaces like aspheric lenses are measured using an objective lens.
Real Time Wavefront Measurement
The advanced software works with all WaveSensor® and WaveMaster® instruments. The overall task of the software is the communication with the Shack-Hartmann Sensor and the analysis of the measured wavefront. In addition, the software controls the WaveMaster ® instruments. Therefore, software modules depending on the specific WaveMaster ® instruments are available, as for example for the production instruments. The software package features a high ease of use, a menu-driven operator guidance and advanced data management, which allows for easy and intuitive wavefront measurement and analysis.
All aspects of data acquisition starting with data calculation, calibration and display of the data are under software control and fully automated. Furthermore, extended tools for live analysis are available. In addition theoretical data can be loaded from ZEMAX and Code V and compared in real time during measurements. |
| OptiCentric® - Automatic Cementing of Achromatic Lens Systems
The manual cementing of doublets requires a high level of mechanical skills and the results could be disappointing if a centration error deteriorates the imaging quality of the achromatic doublet.
With the OptiCentric® Cementing Station developed by TRIOPTICS this cementing process can be significantly simplified and automated for more reliable results. In contrast to the traditional process this new method eliminates the need for precision sample fixtures, and due to the fully automatic procedure it is independent from the mechanical skills and attention of the operator.
The centration error is measured with an autocollimator system in reflection mode according to the ISO 10110-6 standard. With the patented SmartAlign® algorithm the centration of each lens surface within the achromatic doublet is measured automatically and the optimum shift for the upper lens is calculated. This movement is then done within 1-2 seconds with a piezo driven manipulator, achieving a residual centration error between both lenses in the doublet of typically less than 2 microns.
This procedure is independent from the accuracy and stability of any mechanical fixtures since both lenses are directly centered to each other but not to some third mechanical reference. The measurement precision is provided by a high resolution CCD based electronic autocollimator while the sample rotation is achieved by an ultra-high precision air bearing.
A software controlled motorized stage focuses the autocollimator to the center of curvature of each surface for measuring its displacement or tilt. After manual loading the lens pair with added cement the complete centering process including UV curing is done automatically. In total, the complete process of centering and curing takes no longer than a few seconds. Therefore the OptiCentric® Cementing Station is an attractive solution for the series production of achromatic systems.
The instrument software provides records and statistics of the centration results, user definable thresholds for centration tolerances, simple go/no go signals for the final result and a control for the UV lamp.
The cementing station is an add-on to the TRIOPTICS OptiCentric® System for centration error measurement and can be easily adapted to existing instruments with air bearing, but can be also ordered as a turnkey stand-alone system.
Beside the OptiCentric® Cementing Station, the OptiCentric® Bonding Station should not be missed in any optical production. With the OptiCentric® Bonding Station lenses can be assembled and centered to a complete optical system. |
| PrismMaster® - Ultra Accurate and Fully Automated Prisms and Polygons Measurement
PrismMaster ® COMPACT has been one of the most accurate and versatile precision Goniometer on the market dedicated to angular measurements of prisms, polygons, and many other optical components. It is a compact, cost-effective alternative, even for mobile use. If test objects must be measured manually or automatically with an accuracy of up to 1.5-2.0 arcseconds, the PrismMaster® COMPACT is the right choice.
The advantages of the PrismMaster ®
• Significant increase in measurement accuracy due to the use of electronic autocollimators
• Elimination of subjective operator error during the visual adjustment of the test sample
• Very short measurement times and simple operation (no rotation of the measurement head under continuous operator monitoring)
• Simple automation of measurement processes
Typical applications refer to measurement of a diversity of plano optical components and optical parameters:
• Angles of polygons and prisms
• Surface tilt errors of prism and polygons
• Wedge errors, parallelism of optical windows
• Deflection angle measured in transmission
• Index of refraction of optical glasses
• Angles of microprisms
• Pyramidal errors
• Angular gauge blocks
Modern Software with Extensive Functionality
The PrismMaster® software offers an outstanding range of features and contributes significantly to the success of our product line:
• Proven, innovative algorithms allow for angle measurements with unrivalled accuracy (< 0.2 seconds of arc over 360°)
• Absolute measurement of polygons using the rosette technique, with subsequent calibration of rotary tables, rotary encoders, and other rotating systems.
• Fast detection of reflection images, sorting of distorting images, selection of the right images.
In addition to angular measurement, the software also calculates and analyses the individual measurement results and uses the data to optimize the measurement process. This eliminates, for example, the time-consuming alignment of prism surfaces to the autocollimator axis.
The distinctive feature of the software is its intuitive, menu-controlled user interface and a variety of functions helping to simplify the measurement:
• Preconfigured measurement procedures for polygons, prisms, and other optical components
• Adaptation of measurement procedure to the type of test object: special settings for very small prisms and prisms with anti-reflection coatings
• Compensation for even the smallest inaccuracies in positioning of the test object to the optical axis of the autocollimator (horizon determination)
• Calculation of pyramidal errors in different modes
• Tilt error determination of individual surfaces relative to the surface of the rotation table
• Calculation of the transmission angle after measuring all angles in reflection (the refractive index of the test sample material must be known)
• Easy conversion of the software to a simplified Production Mode
• Automated measurement process with tolerance input and sorting function
• For high-precision measurements: the calibration curve of the encoder is used for correction of the measurement results |
