The MidOpt Bi520-25.4 green interference bandpass filter is used in applications that employ 520nm green laser diodes or 520nm/525nm LED light sources. The latter are typically used in machine vision inspection, while the former are commonly used in bioanalytical applications. Various popularly used fluorophores (e.g., GFP, GelStar, SYBER Green, etc.) have emission maximas at or very near 520nm, and Bi520 filters can be used to effectively block excitation sources and interfering longer and shorter wavelength light while letting this light pass through to the camera’s sensor. All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
