BrightLine full-multiband filter set: FITC & Texas Red and similar fluorophores

Semrock Logo

This new ‘full-multiband’ filter set allows for simultaneous direct viewing or imaging with a color camera. Popular 2-fluorophore combinations include FITC/Texas Red and GFP/mCherry.

Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spectral plot data, please see here for more information.

Optical Specifications
BlockingBrightLine filters have blocking far exceeding OD 6 as needed to ensure a black background, even when using modern low-noise CCD cameras. The blocking is optimized for microscopy applications using our exclusive SpecMaker™ fluorescence filter design.

General Specifications
Microscope CompatibilityBrightLine filters are available to fit Leica, Nikon, Olympus, Zeiss, and Aperio microscopes.
Optical Damage RatingTesting has proven to show no signs of degradation when exposed to at least 6.0 W of power from an unfiltered xenon arc lamp over a 25 mm diameter (corresponding to 1.2 W/cm²) for over 500 hrs.
