Product Overview

Economy longpass filters made from fine-annealed H-K9L optical glass. Select the edge wavelength, passband and diameter; the blocking band is listed for each model. The edge wavelength is defined at half the average passband transmittance, T = Tavg / 2. Transmission and blocking specifications apply to the listed bands at 0° incidence. Behavior outside the listed bands is not specified.
