| Deposition Sciences’ MicroDyn® Sputtered Coatings Include Longwave Infrared (LWIR) Optical Filters
Deposition Sciences, Inc. (DSI®), manufacturer of durable thin film optical coatings, announces the new sputtered long wavelength infrared optical coatings. The company’s proprietary MicroDyn sputtering deposition platform now delivers 8-micron longwave pass (LWP) and 10-micron narrow bandpass (NBP) filters with superior blocking capabilities. The in-band transmittance levels have also been enhanced, making these advanced thin film coatings ideal for a variety of applications, such as gas sensing and thermal imaging.
DSI’s new process creates sputtered films that feature increased abrasion resistance relative to evaporated films and are much more economical to produce in higher volumes. Because of the intrinsically low temperature of the sputtering process, the coatings are compatible with photoresists, enabling the filters to be patterned using standard photolithographic techniques.

| Deposition Sciences Offers Highly Durable, Wide Angle Broadband Anti-Reflective (BBAR) Coatings
• Ideal for gimbal windows and sensor detector assemblies on unmanned systems
Deposition Sciences, Inc. (DSI®), manufacturer of durable thin film optical coatings, announces the design of a wide-angle broadband anti-reflection (BBAR) coating for gimbal windows and detector assemblies. The highly specialized coatings address the needs of unmanned aircraft systems (UAS) for a highly durable, angle-insensitive (FOV 0-30 degrees) glare- reducing coating on sapphire substrates. The design is band-selective, such that minimum reflectance can be tuned to a particular detector package, while still minimizing visibility (glare) in the photopic spectral sensitivity range of the human eye. The design delivers an average reflectance of approximately 2 percent between 400-5000 nm.
Consistent with the harsh operating environments of UAS, the new wide-angle BBAR coatings are environmentally stable and perform to MIL-C-48497 and MIL-F-48616 standards. Testing is performed on the coated windows according to specifications for humidity, salt-fog, abrasion, temperature cycle, adhesion, solubility, and cleanability. In addition, DSI‘s in-house testing facility ensures that cryogenic and operating temperature measurements can be made between 10-400 Kelvin.

| DSI Offers Infrared Narrow Bandpass Optical Filters for Spectroscopy
Deposition Sciences, Inc. (DSI), manufacturer of highly durable thin film optical coatings, introduces advanced Infrared Narrow Bandpass (IR NBP) Filters for industrial, medical, and biological sciences instrumentation. The improved narrow bandpass optical filters offer high spectral performance, with accurate center wavelength placement, and good temperature stability which makes the infrared NBPs ideal for spectroscopic applications such as advanced gas-sensing. The NBP filters’ IR spectral range enables the user to detect a particular gas and to identify the concentration levels of gases such as CO2, CH4, HOx, and more.
According to DSI’s Thin Film Design Engineer, Lucas Alves, “The detection of gas concentrations by spectroscopic techniques is the basis for a variety of applications. The absorption of infrared radiation at wavelengths between 2.0 - 20.0 microns provides a definitive signature of the bending, stretching, and/or twisting of the atomic bonds in a particular gas molecule. DSI’s IR narrow bandpass filters allow discretization of the spectra through a gas sample at multiple detection wavelengths, inside and/or outside the absorption band of interest.”
Thin film optical coatings are widely used for non-diffractive infrared (NDIR) sensing systems and other measurement tasks. DSI’s NBP filters are calibrated for center wavelength (CWL) placement to offset temperature shifts that are native to this spectroscopic measurement technique. They also feature reliable and repeatable transmittance characteristics which are essential for high performance in any gas-sensing application in the infrared.

| Infrared Narrow Bandpass Optical Filters for Spectroscopy
Deposition Sciences, Inc. (DSI), manufacturer of highly durable thin film optical coatings, introduces advanced Infrared Narrow Bandpass (IR NBP) Filters for industrial, medical, and biological sciences instrumentation. The improved narrow bandpass optical filters offer high spectral performance, with accurate center wavelength placement, and good temperature stability which makes the infrared NBPs ideal for spectroscopic applications such as advanced gas-sensing. The NBP filters’ IR spectral range enables the user to detect a particular gas and to identify the concentration levels of gases such as CO2, CH4, HOx, and more.
According to DSI’s Thin Film Design Engineer, Lucas Alves, “The detection of gas concentrations by spectroscopic techniques is the basis for a variety of applications.
The absorption of infrared radiation at wavelengths between 2.0 - 20.0 microns provides a definitive signature of the bending, stretching, and/or twisting of the atomic bonds in a particular gas molecule. DSI’s IR narrow bandpass filters allow discretization of the spectra through a gas sample at multiple detection wavelengths, inside and/or outside the absorption band of interest.”
Thin film optical coatings are widely used for non-diffractive infrared (NDIR) sensing systems and other measurement tasks. DSI’s NBP filters are calibrated for center wavelength (CWL) placement to offset temperature shifts that are native to this spectroscopic measurement technique. They also feature reliable and repeatable transmittance characteristics which are essential for high performance in any gas-sensing application in the infrared. |
| Improved Infrared Reduction Filters for CMOS Imaging
Deposition Sciences, Inc. (DSI), manufacturer of highly durable thin film optical coatings, announces an improved filter specially developed to reduce the infrared (IR) and transmit the visible wavelengths in camera applications. Because CMOS sensors are particularly sensitive to unwanted IR wavelengths, DSI’s improved CMOS IR Filter is designed to block up to 99.5 percent of the IR radiation while transmitting more than 85 percent of the visible.
The improvement in the new infrared filter is critical to CMOS imaging systems that require a highly effective, stable, and uniform IR reduction. The optical thin film coating can be applied to glass as thin as 0.003 inches, which can be used as an encapsulating cover glass for devices being flooded with damaging environmental infrared.
The advancement in DSI’s new IR filter can significantly improve the signal- to-noise ratio in visible CMOS imaging systems that are subject to unwanted IR radiation. It is ideal for use in camera applications where it is critical that IR radiation is blocked to reduce the effects of extraneous light and to improve clarity and contrast in the imagery.
DSI’s proprietary MicroDyn® sputtering technology yields high performance CMOS IR filters. This highly durable, uniform coating is extremely stable over temperature and humidity changes. |

The dual band coatings allow one lens to be used for either wavelength, reducing the need for lens inventories. The IsoSphere AR coated ball lenses reduce device assembly costs because there is no need for orientation of the lens in a device since the coating is uniform over all. A wide choice of lens materials, with indices from 1.44 to 2.15 (at 1550 nm), also helps minimize costs while permitting maximum freedom in the optical design.
Featuring hard, scratch resistant coatings (passes 20 eraser rubs), DSI’s AR ball lenses are bondable by a wide variety of methods making them ideal for use in new or existing optical designs. They offer an affordable and a mechanically-simple optical solution for coupling and collimating applications, e.g. the output of an optical fiber or laser diode. They are also ideal for fiber-to-fiber, diode-to-fiber, and fiber-to-detector coupling when access to the beam is required. |
