light from deeper UV excitation sources and deep red and near-IR (NIR) wavelengths
0% transmission across the visible (VIS) spectrum
Circular polarizers are recommended for eliminating glare from spherical surfaces or in cases where an auto-focus or metering system is used
Chlorophyll Vegetation Index CVI = (NIR * Red) / (Green ^ 2)
the GM6HR31214MCN ensures compatibility with a wide range of imaging sensors
Neutral Density (ND) Filter - Absorptive 0.01% Transmission, 425-675nm - MidOpt ND400 ND light from deeper UV excitationThe MidOpt ND400 Neutral Density (ND) Filter has an optical density of 4. 0, or average 0. 01% transmission across the visible (VIS) spectrum. The ND400 has identical male and female threads on either end so it can be stacked with other ND filters to achieve various optical densities. Because the glass substrate is absorbing 99. 9% of the light that passes into the filter, these filters are not recommended for use with lasers or immediately in front
