Optical filter manufactured by Vortex Optical Coatings. It is a bandpass filter that allows for continuous variable adjustment in the infrared range with a single piece.
The infrared linear variable filter is a bandpass filter that can continuously vary with a single filter in the IR band. By combining it with an appropriate detector and replacing each component, significant savings in space, cost, weight, and time can be expected. Specifications and Features The standard products include three types with the following transmission wavelength ranges: 0.9μm to 1.7μm, 1.2μm to 2.5μm, and 2.5μm to 5.0μm. The size for all three types is 15mm x 3mm, t=0.5mm (tolerance +/-0.1mm). 1. Durable hard coating: MIL C 48497 2. Peak transmittance: 60% (typically) 3. Half-width: 2% of the peak wavelength 4. Surface quality: 60-40 scratch dig 5. Blocking: OD3
