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.
"Photooptic" Ltd. produces about 15 standard color coatings on glass substrates of 0.5-1 mm thickness.
Below are the most popular dichroic filters.
Light blue B52
* 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.
