3. Color filters

Color dichroic light filters have become a modern solution to the problem which was common to equipment used in theaters, advertisements, architecture.

Durable dielectric coatings obtained by vacuum deposition  are non-fading and ensure richer colors compare to traditional coloring media (bulk colored glass, gelatin).

Dichroic filters can withstand high thermal loads and operate at temperature up to 350° C.

* Note: the color shown may differ slightly from the original for various reasons.

Interference systems on heat-resistant glass substrates usually operate at angles of incidence from 0 to 45 degrees. The color of coating significantly depends of AOI.

 

For a number of devices this is a harmful effect, in other cases it creates a mesmerizing play of colors.

Photooptic Ltd. manufactures light filters of non-standard sizes and shades according to the  customer requirements.
