Neutral Density Filters - Reflective

UQG ND Filters reflective are non-absorption filters which can control the light over a extensive spectral range. We have a wide range of different density’s available which can also be purchased to increase the required density by stacking them. These filter are ideal for laser applications due to its metallic coating.

Reflective coated metallic ND filters are coated in two glass types. The visible IR range is nd coated on optical glass to cover 350nm to 2500nm. The UV range is coated on fused silica for use down to 170nm. Please be aware the densities are coated for 550nm, but in the UV this will give up to 40% higher density.

UQG Optics offers a wide range of density’s with a custom additional options like calibration certificates, boxed, transmission/absorbance curves and many more.

Please contact our sales team.
