Product Family Description

Ideal for NIR Wavelengths 700-1100nm
Optical Densities Ranging from 0.3 to 3.0

Our TECHSPEC® Reflective NIR ND filters feature a spectrally flat region between 700 and 1100nm, outstanding parallelism, and exceptional surface characteristics. The combination of high tolerance and broadband performance makes our filters ideal for attenuating a wide range of IR sources. The UV Fused Silica substrate features a low coefficient of thermal expansion and excellent surface quality, making these filters suitable for attenuating low power lasers including lasers at the 1064nm Nd:YAG wavelength. Other applications include NIR spectroscopy, machine vision, and analytical chemistry. The filters may be stacked to obtain a variety of optical densities. Orient mirrored side towards source at 0° angle of incidence. Optical Densities of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 available in a Pre-Loaded Filter Wheel.
