The LVF 0.9-1.7-3.5-15-0.5-2% from Vortex Optical Coatings is a Linear Variable Optical Filter that allows transmission at a wavelength of 0.9 µm - 1.7 µm. It has a transmission of 50 - 75% across the band and an optical density above 2.5 (average) outside the transmission band. This optical filter has a bandwidth (FWHM) of 2% times the center wavelength and blocking range from UV to NIR. It has a gradient of change of 60 nm/mm and an angle of incidence of 0º. This optical filter has a scratch & dig surface quality of less than 60 - 40 and the substrate measures 15 mm x 3.5 mm x 0.5 mm. It is ideal for compact mini spectrometers, gas analysis, and plastics identification applications.
