What is typical application for 710nm bandpass filters?
What is key parameter when choose for Infrared (IR) cut-off filter?
When selecting a Infrared (IR) cut-off filter, the cut-off wavelength is designed at 50% transmittance. It’s 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. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Fitlers, IR cut-off Filters, Longpass & Short Filters,Notch Filters, ND filters, Star filters and Optical sapphire block.
other IR cut-off filters in stock from Liyuan Optoelectronics: IR600 IR630 IR650 IR680 IR700 IR730 IR750…etc.
What is typical application for A shortpass filters?
1. Short pass filters are widely used in fluorescence microscope and optical photography imaging. They effectively eliminate unnecessary light sources or excitation light sources, and separate the signals of different fluorescent probes.
2. Short pass filters also play a significant role in machine vision, allowing some visible light to pass through while blocking infrared light, enabling CCD and CMOS sensors to display more realistic images.
