Reflective Neutral Density Filter Unmounted (Visible) 50mm Diameter 60％

FND-50C02-60

Skip to the beginning of the images gallery

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.

Details

◦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.

Name	Reflective Neutral Density Filter Unmounted (Visible) 50mm Diameter 60％
Weight	0.0100kgs
Standard Coatings Available	No
Guide	Different size, wavelength and deviation not mentioned on-line or in our catalog are available as custom product upon on request.
Remark	-
Attention	Chrome coating is an absorptive material and can not be used with high power pulsed laser. The thermal lens effect may happen on filter with high power laser, for high power laser or high energy laser, please use our variable beamsplitter (model VBS). WEB Reference Catalog Code/W3022 The reflected light off of the filter is dangerous for eyes, please make sure a non-reflective material at the edge end of the light. A vertical light into the filter may have feedback light back into the laser source, it may make an instability to the laser oscillator. To avoid this phenomenon please incline the filter at a small angle. The filter with 92% transmittance rate (model FND-92 and others) is non-coated on both surface. The reflectance is about 4% on each surface, and so, 8% total loss.
