Precision Glass & Optics in avionics applications

Share this on social media:

Precision Glass & Optics (PG&O) has developed a range of custom optical filters for PRP Optoelectronics (Towcester, UK), an independent manufacturer of LED-based displays. PG&O has provided precision narrow-cone-angle optical filters for PRP’s custom avionics displays.

The specialised thin film filters designed by PG&O have been integrated into PRP Optoelectronics’ avionics displays to modify the viewing angle and eliminate unwanted stray light that would otherwise distract the pilot and cockpit crew. The new optical coatings’ operational wavelengths and angle requirements are customised for sensitivity to night time lighting. The precision thin film filters make it easier for the pilot to read the altimeter, the air speed indicator display, etc., in all lighting conditions, even at night. This advanced technology resolves what has formerly been a very serious challenge in military and commercial cockpit display/lighting ergonomics.
