filters feature superior spectral stability and physical durability
characteristics. No degradation of performance
is apparent with ageunlike commonly
used organic dye or gelatin filter systems. Filter coatings are hard,
all-dielectric coatings, extremely durable
when exposed to humidity, heat, thermal shock, abrasion and handling.
They are manufactured to meet the
standards of MIL-C-675A and MIL-M-13058C. Dimensions: 2" dia. ×
0.04" thick.Passband is from 390 nm to 520 nm.
