This is an experimental assembly, of a size for a small exit lens typical of the F-5 HUD, where the Combiner glasses employ a diffractive layer sandwiched between two glass plates. The dichromated gelatin technique is used to optically grade the coatings for a uniform transition. These coatings are also much more frequency selective in their response to the CRT p53 phosphor such that a higher symbol luminance and higher outside world transmission are both achieved albeit with a slight pink tinge to the outside world as the P53 frequency spike is removed from the outside world spectrum. The display can achieve greater than 80% photopically weighted transmission through the combiner, while maintaining up to 80% reflection of the display. This Combiner may have been made in the Company Falcon building or by Pilkingtons (now Qioptic).
