Umicore Materials Short Wavepass Filter Short Wavepass Filter

Short wavepass filters are designed to achieve efficient separation of adjacent spectral bands. The cut-off edge of the filter may be located between 0.85 and 13 microns. Specifications Tpeak Typically >85% Spectral - additional Transmission >70% at wavelengths shorter than the cut-off edge. Extent of transmission region is typically in the ratio of 2:1 Attenuation <0.1% outside passband Edge Slopes 3%-5% typically Environmental Properties Adhesion MIL-C-48497A, 08/09/1980, para 4.5.3.1 Adhesion Remark Tape Test Humidity MIL-C-48497A, 08/09/1980, para 4.5.3.2 Humidity Remark 24Hrs, 49°C, 95-100% relative humidity Abrasion MIL-C-48497A, 08/09/1980, para 4.5.3.3 Abrasion Remark Moderate, 50 strokes with a cheesecloth
