Semrock has increased the flexibility of its EdgeBasic family of long pass-edge filters with the addition of 10 laser wavelengths to the 19 currently on offer 

The EdgeBasic filters provide a combination of steep edge locations (from 325nm to 1319nm) with extended blocking at and below the laser line, which is combined with consistent and extended high transmission pass bands.

EdgeBasic filters are ideal for fluorescence imaging and metrology applications. Used in application-specific Raman spectroscopy, they are suitable when exceptional laser-line blocking is required and the Raman shift measurement is not too small.
