LAS-BT™ NexGen
Introducing OATi’s next generation benchtop model of Lens Alignment and Assembly Station (LAS-BT™). LAS-BT™ NexGen is a metrology-grade instrument designed for high-precision lens centration and tilt measurements on single element, doublet, triplet, and multi-element lens assemblies with radius ranging from +/- 1.0mm to infinity (plano) and diameters from 1mm to 150mm (60kg payload), including spherical, aspheric, cylindrical and parabolic surfaces. All this can be done with a single objective lens allowing for a fast and easy measurement. Improved vertical stage with 0.1 µm vertical encoder option for precision Vertex (CT, air gap) and ROC measurement

LAS-BT™ NexGen, benchtop model of our lens alignment and assembly system is the best lens centration and assembly tool available for smaller optical assemblies. It has a unique laser-based technology that offers several measurement and performance advantages over the traditional autocollimator used by our competitors. What benefits does the new design offer?

1. Improved flatness and straightness of vertical travel >>> more accurate alignment
2. Improved tolerance to changes in ambient temperature
3. Improved resistance to vibration
4. Higher precision vertical stage >>> ball screw with safety cover, no pinch points
5. Higher resolution vertical encoder option >>> more accurate Vertex and ROC measurement
6. Comparable centration and height measurement performance to larger models but in a smaller footprint

INCLUDES:
• Green (520nm) laser reflection based Optical Module
• 533mm vertical linear focusing movement with micro-stepping motor and high-precision rotary encoder
• Ø100mm motorized air-bearing spindle (ABS) with vacuum through center
• Ø150mm integrated x/y/tip/tilt stage
• CalcuLens™ Assembly software for measuring alignment errors of single, cemented doublet and triplet lenses

LAS-BT™ NexGen is a 155 lb version of the standard 6200 lb LAS-XUP™, at a lower price point that delivers the same high precision but for smaller lens assemblies. It is designed for aligning and cementing doublets or triplets, aligning and centering lenses during small lens-assembly, or inspecting completed small assemblies for centration and tilt quality assurance. The same easy operation and user-friendly software is included in the updated benchtop as in the entire LAS family. LAS does not require an engineer to operate it. Technicians can be trained in a just a few hours and will quickly become experts in its use.
