Part Number

IR-ND-1

S$562.50

The metal reflection coating provides an extremely smooth transmission characteristic from the 2μm to 14μm wavelengths.
The substrate thickness is 1mm +/−0.2mm with no difference with the transmittance.

Guide	Different size, wavelength and deviation not mentioned on-line or in our catalog are available as custom product upon on request.
Attention	Metallic coating is an absorptive material and can not be used with high power pulsed laser. 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 unstability to the laser oscillator. To avoid this phenomenon please incline the filter at a small angle.
