Abstract
Aiming at the protection of reflective main optical system for shipboard photoelectric tracking systems
an 1 m size optical window and its frame were designed
manufactured and tested. Firstly
the performance and strength of the window material were analyzed. According to the influence of the difference between internal and external pressures
the weight and the rotational inertia force on the window
the minimum thickness was determined. Then
the effects of deformation of optical window and frame on optical path difference and the environmental adaptability were studied base on the index requirements. Moreover
the aplanatic non-planar grinding method was used for machining and inspecting the optical window. Finally
an fused silica optical window with 1 032 mm in diameter
80 mm in thickness and 1 010 mm in aperture diameter were successfully developed. The optical path difference is RMS=0.062 8
λ
@632.8 nm. The results proves that the optical window can provide an effective protection for main optical system of photoelectric tracking systems.
