Edmund Optics Techspec Hard Coated 25 nm Bandpass Interference Filters

Delivering high transmission with deep blocking, Edmund Optics’ Techspec Hard Coated 25 nm Bandpass Interference Filters are suitable for a wide variety of life science applications, as well as for use in machine vision applications.

The precision filters are designed to serve as a good mid-range alternative to broadband or narrowband filters. Suitable for single photon microscopy, the filters prevent photobleaching in delicate live samples or fluorophores in a broad range of life science microscopy applications.

The filters are a good choice when used to eliminate unwanted background noise, while simultaneously enhancing the signal-to-noise ratio in imaging or machine vision applications. Hard-coated for durability, the filters meet Environmental Standard MIL-STD-810F and Durability Standard MIL-C-48497.

A variety of filters are available, with centre wavelengths (CWL) from 400 to 950 nm, with 12.5, 25 or 50 mm diameters available. 10 and 50 nm filters are available.
