650 – 1300 nm Semrock® General Purpose Mirror

Semrock Logo

Semrock’s General Purpose Mirrors offer high reflectivity with an ‘Imaging flat’ reflection.


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.
