BrightLine® long-pass filter set, optimized for most Qdot Nanocrystals and other like fluorophores

A special long-pass emission filter in this filter set allows simultaneous viewing by eye or with a color camera of samples that are multi-labeled with quantum dot nanocrystals. It takes advantage of the unique fact that all quantum dots share a common UV/blue excitation spectrum while simultaneously exhibiting narrow and specific visible emission spectra. The highly transmitting, deep-blue exciter efficiently excites all quantum dots with no UV light to damage samples or generate undesirable background, while the high and uniform transmission of the long-pass emission filter provides exceptional and balanced brightness. And with the "no burn-out" performance shared by all BrightLine filters, the permanent performance of this set will outlast even your quantum dots!

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.
