Reticle etched within optical lens

A reticle which does not emit a retro-reflective signature detectable using standard field detection means at the standard distance of 10 miles, which reticle is formed of a precise series of about 10 micron wide lines etched within a physically light weight, single optical blank or glass lens, usin...

Zusammenfassung:A reticle which does not emit a retro-reflective signature detectable using standard field detection means at the standard distance of 10 miles, which reticle is formed of a precise series of about 10 micron wide lines etched within a physically light weight, single optical blank or glass lens, using a femtosecond near IR wavelength pulsed laser.
