What is 480nm Bandpass Filters?
A 480nm bandpass filter is an optical device that selectively transmits light centered at 480 nanometers while blocking light at other wavelengths.
What is typical application for 480nm bandpass filters?
480nm bandpass filters are widely applied in fluorescence microscopy and biological optical detection to isolate target blue-cyan fluorescent signals and suppress stray light, and they are also commonly used in water quality monitoring, environmental spectral analysis, color measurement equipment, medical optical systems, industrial machine vision and light source calibration for accurate spectral screening and stable optical signal acquisition.
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, with a tolerance of generally +/-5nm or +/7nm which depend on the user inquiry. Secondly, Peak and Average Transmittance, e,g. 90%,95%…etc. higher transmittance might need Anti-reflective(AR) coating.
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.
Other typical Bandpass filters in stock from Liyuan Optoelectronics include BP810 BP820 BP830 BP840 BP850 BP860 BP870 BP880 BP890 BP 900…etc.
