Reflective Neutral Density Filter Mounted (UV) 25mm Diameter 70％
MFNDU-25-70
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.
◦We are using synthetic fused silica substrates for high transmission at UV range for the UV ND filter. We can obtain almost the similar transmittance at the Near UV and the visible range.
◦The substrate thickness is 2mm +/−0.1mm with no difference with the transmittance.
