3.What is typical application for 560nm bandpass filters?
A 560nm bandpass filter is an optical device that selectively transmits light within a narrow wavelength range centered at 560nm while blocking all other wavelengths. Typical applications for 560nm bandpass filters are very broad, include fluorescence microscopy, flow cytometry, biochemical analyzers, plant photosynthesis research, industrial color sorting/vision inspection, and portable fluorescence sensors.
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.
