Universal Raman filter

Model 275DS is a subtractive-dispersion double monochromator featuring two 0.2-m normal-incidence monochromators. Aberration corrected holographic gratings are used and feature a solid f/4.2 collection angle. The 275DS provides OD 6 rejection at 100/cm from 514 nm and operates as a universally tunable filter whose central wavelength can be set from less than 185 nm to 2 µm. Bandwidth passing through the monochromator system can be continuously varied via bilaterally adjustable slit apertures
