785/10 nm MaxDiode™ laser clean-up filter

Semrock Logo

Keep the desirable laser light while eliminating the noise. MaxDiode laser clean-up filters are ideal for both volume laser-based instrumentation as well as laboratory use of diode lasers for fluorescence excitation and other spectroscopic applications.

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.
