What is typical application for 950nm bandpass filters?
Typical application for 950nm bandpass filters is very broad, include moisture detection & analysis, gas sensing & environmental monitoring, night vision & surveillance imaging, biomedical & physiological monitoring, optical communications, industrial machine vision & sorting, automotive LiDAR & sensing, solar cell & semiconductor inspection, astronomical & atmospheric studies…etc.
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…etc.
