Semrock Filter Set: LF442-B

BrightLine® single-band laser filter set, optimized for 442 nm laser sources

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.

Our improved version is certified to deliver dichroic flatness <= 1λ P-V RWE @ 632.8 nm for loose and cube mounted [NTE, OFF, OMF or ZHE] filter sets LF442-C
