Low OH IR grade fused silica allows for exceptional transmission up to 3 microns. Combined with a low coefficient of thermal expansion, superior homogeneity and low birefringence, low OH IR grade fused silica is an outstanding alternative to significantly more expensive IR materials. Applications of interest include process control and inspection using machine vision, high resolution SWIR imaging, remote sensing and metrology.
