Applications
The BP515's narrowband transmission at 515nm makes it particularly well-suited for multi-plex luciferase assays, where precise wavelength discrimination is critical for distinguishing multiple reporter signals. Additional applications include fluorescence microscopy, flow cytometry, LED wavelength selection, and environmental monitoring instruments. The filter's deep blocking from 350nm to 1100nm ensures effective rejection of out-of-band stray light, preserving signal integrity in demanding optical systems.
