514 nm EdgeBasic™ best-value long-pass edge filter

Semrock Logo

EdgeBasic filters offer an ideal combination of performance and value for applications including Raman spectroscopy and fluorescence imaging and measurements. They offer exceptional laser-line blocking and high transmission for Raman applications that do not require measuring the smallest possible Raman shifts and when cost is an issue.

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.
