BP320/10nm Bandpass Filter | 320±2nm, 10±2nm, 200-1100nm OD>4

OPTOStokes BP320/10nm is a precision UV bandpass filter designed to isolate the 320nm spectral region with controlled transmission and broad out-of-band blocking. With a center wavelength of 320 ±2nm, bandwidth of 10 ±2nm, and optical density greater than 4 from 200-1100nm, it is suited to UV-Vis analytical instruments and wavelength-selective detection systems.

Technical Specifications

Applications

The BP320/10nm can be integrated into UV Filters and UV-Vis detection systems where selective transmission around 320nm is required. Typical applications include water quality analysis, COD and TOC-related UV absorption methods, online monitoring of dissolved organic matter, and atmospheric UV spectral analysis. In water monitoring, 320nm measurements can be used as part of a broader spectral model for assessing organic matter and other water-quality parameters.

For systems requiring precise wavelength selection, the filter can also serve as a compact Bandpass Filter in analytical and spectroscopy filter assemblies.

Customization & Service

OPTOStokes supports custom filter dimensions and mechanical configurations for instrument integration. Available formats can include round, square, and irregular shapes, with mounting-ring options when required. Stock configurations support faster evaluation, while custom coating and fabrication can be matched to application-specific spectral requirements. Reliable production scheduling and spectral quality control help reduce sourcing and qualification risks.

Pain Points & CTA

For UV analytical systems, the main sourcing challenges are often wavelength tolerance, blocking performance, mechanical fit, and predictable delivery.
