The Ultrafast Systems imaging monochromator is optimized to work with our time-resolved spectrometers. This monochromator features high spectral resolution, as well as an astigmatism-corrected design, optimal for multipixel array detectors. With its dual exit ports, this instrument can be used as a spectrograph as well as a monochromator.
The monochromator’s focusing matches the design of the main optical bench to maximize the overall spectrometer’s performance.
The monochromator features a 4-grating turret with kinematic mounts for optimal wavelength coverage, optical throughput, and spectral resolution.
The UV-enhanced Al coatings on the monochromator mirrors ensure high efficiency of fluorescence and the upconverted signal collection as well as excellent performance in Mid-IR transient absorption experiments.
