BP500-10nm Bandpass Filter | 500nm CWL, 10nm FWHM, OD5+ Blocking

The BP500-10nm is a high-precision narrow bandpass filter engineered and manufactured by OPTOStokes, designed for optical systems that require precise spectral selection at 500nm. With a center wavelength of 500nm and a 10nm full width at half maximum (FWHM), this filter achieves peak transmission greater than 90 percent at the target wavelength, maximizing signal throughput while maintaining strict spectral control. It provides deep optical blocking across the 350nm to 1100nm range with optical density greater than 5, effectively suppressing out-of-band background noise and improving system signal-to-noise ratio. As a core product in our extensive Bandpass Filters portfolio, it is fabricated with advanced thin-film coating technology for stable, long-lasting performance in both laboratory and field environments.

Technical Specifications

Applications

This 500nm bandpass filter is optimized for a range of environmental and life science optical applications. It is a critical component in Fluorescence Detection systems for chlorophyll analysis and algae monitoring, where precise 500nm spectral isolation enables accurate quantification of photosynthetic pigments in water samples. It is also widely used in water turbidity measurement systems, where targeted wavelength filtering enhances the accuracy of suspended particle detection. Additionally, the filter is well suited for integration into Analytical Instruments, biomedical imaging setups, and industrial inspection systems that require reliable narrowband spectral control and high out-of-band rejection.
