1. Transparent anti-reflection coatings
We produce anti-reflective transparent coatings for the visible spectrum AR-VIS 420-700, for the near infrared AR-NIR-620-1200 and with a wide low reflectance band in the range from 400 to 1000 nm AR-VIS-NIR-400-1000 as well.
In fig. 1 shown the reflection spectrum of the AR-VIS-420-700 anti-reflection coating, in fig. 2 - AR-NIR-620-1200 anti-reflection coating for the near IR region.

Ultra-wideband AR-VIS-NIR-400-1000 AR coating is used for aerospace photography in day and night conditions. The coating provides less than 0.6% reflection in the 400-1000 nm range. The reflection spectrum of the AR-VIS-NIR-400-1000 coating is shown in Fig. 3.
