Middleton Spectral Vision provides several white reference materials that can be used to calibrate hyperspectral images. The material is 95-99% reflective in the wavelength range 450-2500 nm, which covers the NIR to SWIR ranges and most of the visible range. It is a rugged, easily-cleaned alternative to other white reference materials.
Available in 23 mm and 42 mm diameter optical areas, square optical areas and a large 13” x 13” square. Recertification also available for standards from other manufacturers.
