Beamsplitter/compensator optics

Optical Surfaces Ltd has been selected by a leading spectrophotometer manufacturer to supply ultra high precision matched beamsplitter/compensator optics for the interferometer that lies at the heart of its high resolution FT-IR system.

To achieve this performance Optical Surfaces is manufacturing the 100mm diameter OA grade fused silica beamsplitter and compensator optics with a surface accuracy of lambda/20 (p-v) and wavefront error in transmission of lambda/20 (p-v) at 633nm. Further each beamsplitter/compensator pair is tightly matched in thickness and wedge angle.
