Semrock Filter Set: FITC-5050A

BrightLine® single-band filter set, optimized for FITC and other like fluorophores

This set is optimized for the most popular green fluorophores like FITC (fluorescein isothiocyanate), 5-FAM, and Alexa Fluor 488. It provides the highest brightness and is ideal for similar fluorophores that have narrower, more closely spaced excitation and emission peaks, like BODIPY.

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
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
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.

Physical Filter Specifications
Exciter/Emitter OrientationArrow on ring indicates preferred direction of propagation of light.
Dichroic Orientation"Reflective coating side" should face toward light source and sample.

5-Star Optimized – Filter set is specifically optimized for that fluorophore.
3-Star Compatible – Should result in nearly ideal performance in most situations.
1-Star Acceptable – Actual performance is dependent on specific experimental conditions.
