Avant™ single-band filter set: Cy5.5™, Alexa Fluor 680 and similar fluorophores

Semrock Logo

This filter set is designed for use with Cy5.5™ and Alexa Fluor 680 and works well with other deep-red and near-infrared fluorophores. The Avant™ filter set family delivers significant increases in fluorescence performance for small Stokes Shift fluorophores compared to standard filter sets. Steep spectral edges and high complementary OD blocking maximize signal while maintaining low bleedthrough and high signal to noise ratio. The new Precise Edge Placement capability ensures every filter set delivers consistent performance.

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
Blocking Avant filters have blocking far exceeding OD 5 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 Compatibility Avant filters are available to fit Leica, Nikon, Olympus, Zeiss, and Aperio microscopes.
Optical Damage Rating Testing 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.
