442-26_543-108 OD6 ULTRA Dual-Bandpass Filter



442-26_543-108 OD6 ULTRA Dual-Bandpass Filter


ULTRA Series dual-bandpass filter with 442 nm and 543 nm center wavelengths (CWL) and full-width at half-maximums (FWHM) of 26 nm and 108 nm, respectively. This dualband optical filter has exceptionally steep edges, greater than 93% average in-band transmission, and wide-range OD6 out-of-band blocking from 350 nm to 700 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.
