3.What is typical application for 600nm bandpass filters?
A 600nm bandpass filter is an optical device that selectively transmits light centered around the 600nm wavelength while blocking light outside this range. Typical application for 600nm bandpass filter is very broad, including biomedical & clinical instrumentation, spectroscopy & chemical analysis, laser systems, industrial & quality control, imaging & machine vision.
4.What is key parameter when choose for right bandpass filter?
When selecting a bandpass filters, the center wavelength (CWL) will be one of key parameter to be designated, it refer to the wavelength at which the filter achieves maximum transmission. Secondly, Peak and Average Transmittance, typically ≥80–95%, higher transmittance might need Anti-reflective(AR) coating. Third, full width at half maximum (FWHM). Forth, Blocking Range & Depth. Fifth, substrate material, e.g., BK7, B270, fused silica, colored glass. Sixth, surface quality, e.g., 60/40, 40/20. Seventh, Size & Shape, etc.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nanomaterials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Filters, IR cut-off Filters, Longpass & Short Filters, Notch Filters, ND filters, Star filters and Optical sapphire block.
