Patent ID: 8292459

Claim:
An illumination device for use in night vision goggles comprising: a. A light intensifier in a night vision goggle; b. At least one carpet of laser diodes including i. Green diodes that emit light in a spectral band situated in the green, ii. Blue diodes that emit light in a spectral band situated in the blue, and iii. Red diodes that emit light in a spectral band situated in the red; c. An optical plate positioned above the carpet of laser diodes, said optical plate including: i. Zones situated above selected ones of the red diodes which function as an interferential filter having an optical transmission cutoff wavelength in the range from about 620 nm to 640 nm; and ii. Having a height of the optical plate and the distance of the optical plate above the carpet of laser diodes being selected such that only a portion of the light from the selected red diodes is acted upon by the interferential filter, the remainder of the light is being transmitted without being filtered.
