产品介绍
Antiveiling photoelectric glass (AVG) has characteristic of high transmission from UV to visible light in the effective area, while the transmission is almost zero in the high absorption layer. This layer is prepared by a special process and then it has a very strong absorption to stray light. So, photoelectric glass can eliminate flare, and improve clarity of night vision devices and other optical elements.
Effective aperture：Φ16~40mm
Coefficient of expansion：（50±2）×10-7/℃
nD：1.4960
Transmittance in effective area：≥90%
White light transmission of black layer：≤2%
