Optical Design

A large range of optical materials are used including different types of glass in the visible range and IR materials like Gallium Arsenide, Germanium, Silicon etc. Many optical components are manufactured in-house including precision prisms, precision windows and mirrors, Ge lenses of up to 300 mm diameter with ?/30 wavefront error, and multi-layer optical coatings are designed and performed using PVD, IAD, CVD and IBS deposition technologies. Test capabilities include laser unequal path interferometers (LUPI), wavefront deformations (VIS and IR), monochromatic and polychromatic MTFs and MRT for IR systems.
