| The main function is to make the narrowband filter specific wavelength of light by reflection, let the other wavelengths of light (or decay) optical elements. Half wave width is usually controlled at 20nm or less, can be ultraviolet, visible light and near-infrared wavelengths, the far infrared band. We adopt the multilayer filters by ion assisted deposition with nano materials high vacuum evaporation coating, good co***ctness, high imaging definition. Application: 440nm laser 440nm blue diode infrared camera medical instrument fluorescence microscopic analysis instrument tunable laser ink recognition product size: 1) 11mm * 14.0mm * 1.1mm 2) + 0.1 * 1.1 + 25.4 diameter 0.1mm 3 7.0mm * 7.0mm * 1.10mm) 4) can be customized according to customer requirements: K9 material transmittance >90% cut-off depth: od6 incident angle: the surface quality of 0 DEG or 45 degrees: 40/20 aperture >90% wavelength with temperature change: Damage threshold: 300mw/cm2cw, <0.25nm/ C 1j/cm2pulsed product model: gi-bp440-40 material: optical glass (environmentally friendly RoHS) with center wavelength of 440nm + 2nm central wavelength transmittance >85% peak transmittance of >85% bandwidth: 40nm + 2nm: 200nm~400nm, 500nm~1100nm cutoff cutoff rate: t<0.1% appearance: 60/40 product features: monolithic without the use of glue.
