526-23 OD7 ULTRA Bandpass Filter



526-23 OD7 ULTRA Bandpass Filter


ULTRA Series bandpass filter with a 526 nm (± 1.5 nm) center wavelength (CWL), a 23 nm full-width at half-maximum (FWHM), and wide-range OD7 out-of-band blocking from 350 nm to 925 nm. This bandpass filter has exceptionally steep edges and greater than 95% average transmission from 517 nm to 535 nm. It is coated on a 2 mm thick fused silica substrate and mounted in a standard 25 mm (+0/-0.1 mm) diameter, 3.5 mm (± 0.1 mm) thick anodized aluminum ring. Alluxa ULTRA Series fluorescence filters are designed to optimize fluorescence instrument performance, resulting in bright, high contrast images of target molecules. ULTRA Series filters provide better overall performance than our standard fluorescence filters by using a combination of tight wavelength control, ultra-steep edges, deeper blocking, and the industry's highest transmission levels. All Alluxa optical filters are highly durable and hard-coated using our innovative SIRRUS™ plasma deposition process. Contact us for custom sizing.
