Semrock Optical Filter: BLP02-1319R  BLP02  1319R
1319 nm EdgeBasic™ best-value long-pass edge filter
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.
