LBTEK-Reflective Neutral Density Filter, wavelength range: 200 nm-1200 nm

Product Description

Substrate material: UVFS
Wavelength range: 200-1200 nm
OD: 0.1-4.0
Low power application
Reflective neutral density filter

The LBTEK NDFR-UV series reflective neutral density filters are specifically designed for light attenuation in the ultraviolet to near-infrared spectral range. These products use a UV fused silica (UVFS) substrate with a single-side coated nickel-chromium-iron alloy film, providing a flat spectral response across a broad range of 200 nm-1200 nm. The optical density (OD) of each filter is specified at a design wavelength of 300 nm for convenient use in the ultraviolet band. Within the entire usable wavelength range, the OD value may vary to a certain extent. The filters have a diameter of 25.4 mm and a thickness of 2.0 mm, and are available in two configurations: unmounted bare substrates and pre-installed SM1 lens mounts. Additionally, the product covers 15 attenuation levels from OD 0.1 to OD 4.0, meeting the needs of different experimental scenarios ranging from slight attenuation to deep blocking. LBTEK also offers custom solutions for attenuators with other special sizes and optical density values. Please contact technical support if needed.
