BP525 Light Green Bandpass Filter
Light Green Bandpass Filter for machine-vision imaging — passes 500-555nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
BP525 filter material is designed for use with green LED lighting, 532nm laser illumination and green UV fluorescence applications. A BP525 filter has a broader range, higher peak transmission and superior blocking of UV and NIR wavelengths compared to commonly found all-dichroic green bandpass filters – improving contrast by blocking significantly more of the unwanted light. Because of its filter glass substrate, it is also less sensitive to changes in angle of incidence.
