BrightLine® single-band laser filter set: 442 nm laser sources

Discontinued. Limited stock remaining.

Semrock Logo

This set is designed to take advantage of the superior resolution, sensitivity, and image fidelity of today’s state-of-the-art laser-based microscopes. The filter spectra are optimized to capture the maximum fluorescence from CFP and other similar fluorophores while offering superb blocking of popular 442 nm (solid-state) lasers. The dichroic offers excellent flatness for minimal focus shift and aberrations of the laser beam spot at the sample.

Looking for this filter set in one of the following cubes: NTE, OFF, OMF or ZHE?

Our improved version is certified to deliver dichroic flatness <= 1λ P-V RWE @ 632.8 nm for loose and cube mounted filter sets LF442-C

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 BrightLine 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 Compatibility BrightLine 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.
