Products Description
BP525-85nm Bandpass Filter | CWL 525nm, FWHM 85nm

The OPTOStokes BP525-85nm is a high-transmission green bandpass filter designed for machine vision and industrial imaging systems. It provides more than 90% transmission across 500–560nm, centered at 525nm, while delivering optical density greater than 2 blocking from 350–1100nm. This spectral profile helps isolate the target visible band while suppressing unwanted broadband light reaching the imaging sensor.

Applications
The BP525-85nm is suitable for machine vision and industrial imaging systems that require controlled visible-band detection. Its 500–560nm transmission range supports green-region spectral selection, while broadband blocking from 350–1100nm helps reduce unwanted spectral background at the sensor. For engineers evaluating related Bandpass Filters, CWL, FWHM, transmission, and blocking should be considered together with the detector response and illumination spectrum.

Customization & Service
OPTOStokes offers both in-stock optical filters and custom filter solutions for OEM and R&D requirements. The BP525-85nm can be supplied in round, square, or custom irregular shapes, with optional mounting rings for integration into optical assemblies. Custom dimensions, spectral requirements, and mechanical configurations can be reviewed according to the application, with controlled lead times and consistent production quality.
Pain Points & CTA
For machine vision development, the main procurement risks are often uncertain spectral performance, limited customization, and inconsistent delivery. OPTOStokes provides standard selection for faster sourcing together with technical support for custom requirements.
