Neutral Density Filters - UV Reflective

UQG Optics UV/VIS Neutral Density Filters have a Ni chrome metallic coating which enhances the absorption to the desired spectral transmission. Part of the rejected light is absorbed and the remainder is reflected, so these filters can also be used as beamsplitters. This coating is coated on UV Fused Silica with a transmission range from 250 to 1000nm range, using 550nm for the density range which in the UV will give you up to 40% higher density. These filters have high surface and parallelism attributes which make them ideal for a range of applications including laser applications.

We supply Optical Neutral Density Filters in stock diameters and squares and can custom make with AR coatings, calibration certificates and boxed.

Please contact our sales team.
