Reflective Neutral Density Filter Unmounted (Visible) 25mm Diameter 70％
FND-25C02-70
The reflective ND filter is used for high power and broadband wavelength light density reducing. The untransmitted light would not be absorbed, there is no possibility of glass damaging by the heat.
◦The metal reflection coating provides an extremely smooth transmission characteristic from the UV to IR wavelengths.
◦The substrate thickness is 2mm +/−0.1mm with no difference with the transmittance.
