What is 480nm longpass filter?
A 480nm Longpass Filter is an optical component that allows light with wavelengths longer than 480nm to pass through while cutting off light with shorter wavelengths.
What is typical application for 480nm longpass filter?
What is key parameter when choose for right Longpass filters?
When selecting a 480nm Longpass Filter, there are several key parameters we need to consider. First, cut-on wavelength, this is the most critical parameter of the filter. Second, transmission rate. The transmission is typically >90%. Achieving higher levels requires optimized coating designs. Third, blocking depth. The higher the OD, the stronger the blocking capability. Forth, edge steepness. Fifth, transmission band range. Sixth, substrate material. Such as N-BK7, B270, Fused Silica, Sapphire. Seventh, dimensions ang incident angle.
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.
