Posted by John McHaleSANTA ANA, Calif., 12 Feb. 2011. Precision Glass & Optics (PG&O) is providing precision narrow-cone-angle optical filters for custom avionics displays from PRP Optoelectronics, an independent manufacturer of light emittign diode (LED)-based display technology in Towcester, England. The specialized thin film filters are integrated into PRP Optoelectronics' avionics displays to modify the viewing angle and eliminate unwanted stray light that would otherwise distract pilots and cockpit crew. The new optical coatings' operational wavelengths and angle requirements are customized for sensitivity to nighttime 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. The technology resolves what has formerly been a very serious challenge in military and commercial cockpit display/lighting ergonomics, PG&O officials say.PG&O offers a variety of glass and thin film coated optical materials, from square, rectangular, and/or circular parts, to complex shapes and all types of precision optical prisms. In addition to optical coatings, the in-house facility has glass fabrication equipment, including grinding, polishing, machining, scribing, engraving, CNC, and assembly. The company supplies glass and coatings for military, biomedical, life sciences, industrial, solar, imaging, aerospace, scanning, digital cinema, astronomy, and laser manufacturing applications.
