TriVista CRS Configuration Option TriVista 557 CRS Princeton Instruments Array Detectors Spec-10 LN-Cooled CCD Camera OMA V InGaAs Linear Array Acton Spectrograph Micro-Raman Interface Triple-/Single-Stage Bypass Switch PIXIS TE-Cooled CCD Camera Micro/Macro Transfer Optics Witness Camera Macro Sample Chamber Olympus Microscope Laser Delivery System TriVista is the only triple spectrometer on the market that can switch between additive and subtractive modes with a single mouse click. Astigmatism-corrected spectrographs with toroidal mirrors provide outstanding imaging across the entire focal plane. -1 Triple subtractive mode resolves Raman spectra to within 5 cm of the laser line. Triple additive mode provides the resolution of a 1500 to 2250 mm instrument. Use as many as three entrances and four detectors on a single TriVista to accommodate multiple experiments and multiple users. Slit confocal design is easy to align and provides high throughput and outstanding out-of-focus light rejection for near-diffraction-limited Raman and luminescence imaging.

Schematic of Spectrograph and Microscope Options for CRS

Separate grating drives and software-adjustable offsets ensure that every configuration is aligned and calibrated. Computer control of mirrors, gratings, and slits in a single window. Interchangeable triple-grating turrets provide experimental flexibility from the deep UV to the short-wave IR. A complete set of plane-ruled and holographic gratings ranging from < 50 to 3600 grooves/mm is available, providing spectral resolution of up to 0.1 cm -1. MonoVista CRS offers confocal Raman and luminescence imaging and mapping in the same platform as TriVista CRS. This is ideal for users that do not require TriVista s flexibility, resolution, and high stray-light rejection. Acton #1900 UV-enhanced aluminum, protected silver, gold, or dielectric optical coatings are available for high light throughput.
