Semrock Filter Set: YFP-2427B

BrightLine® single-band filter set, optimized for Yellow Fluorescent Protein and other like fluorophores

This filter set is optimized to be simultaneously the brightest and the highest signal-to-noise ratio (contrast) available for measuring YFP and its variants – no more compromising or exchanging filter sets for different YFP experiments.

Individual filters and filter sets (no cube):
These filters sets contain individual filters. For filter sets already mounted in a holder/cube, scroll down to see complete mounted sets with cubes.

Optical Specifications
SpecificationValue
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 Filter Specifications
SpecificationValue
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 hours.
