The metallic coatings on one side of the filter provide a nearly constant amount of transmitted energy over a wide visible and near infrared waveband. CDHC's neutral density filters are spectrally neutral from about 400nm to 1200nm. On BK7 or quartz substrates, we produce a variety of standard neutral density films with optical densities(OD) including 0.1,0.3,0.5,1.0,2.0,
