Abstract

A chevron-type dielectric bandpass filter set is described which combines laser line rejection by a factor >108 with a high throughput of Raman scattered light (70%). The rejection bandwidth is 60 cm−1 full width at half-maximum. Stokes and anti-Stokes Raman spectra can be recorded simultaneously from approximately 20 cm−1 from the laser line. The filter set, moreover, takes care of efficient coupling of microscope and spectrometer, replacing an otherwise necessary beamsplitter.
