Fine-optically polished to ensure accurate 1/4 wavefront and <30 seconds parallelism over the both surfaces
95% transmission at passband
Infrared wavelength 700-1100nm cut-off
Precision off-band blocking
Coating Parameter
Multi-layers anti-reflection coating
Non-cementing optical substrate coating
Electron-beam gun evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL(central wavelength) no deviation affected by temperature change
Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off-band
Filter Cell
Ultra-thin filter cell minimize vignetting by maximize possible clear aperture (clear aperture is 26mm for 1.25”; 45mm for 2”)
