ISA TRIAX320 Spectrometer

The TRIAX series uses special corrective optics that maintain an excellent image quality and resolution along the length of the slit as well as along the dispersion axis in the exit focal plane. Thus, a point source on the entrance slit is re-imaged as a point for every occurrence of its wavelength in the focal plane. This makes TRIAX instruments the ideal spectrographs for a wide application range of high resolution multichannel spectroscopy.

All TRIAX spectrographs have been optically optimized by using toroidal mirrors and an asymmetric optical path for superb exit imaging quality with the lowest re-entrant and stray light. TRIAXs are also equipped with larger focusing mirrors for a maximized non-vignetted and maximum optical throughput. Each spectrometer in the TRIAX series can be provided with up to three gratings mounted in a single turret. This allows for tremendous flexibility in the choice of the gratings for optimum resolution and desired spectral rang

The turret in the TRIAX series is the result of our latest technology. Our unique patented on axis triple grating turret, allows the TRIAX to maintain on-axis grating rotation during scanning, keeping a constant f number and image quality whatever the working grating and its position. A high-speed drive and precise motorized slits fully automate the adjustments on the TRIAX. Several options are available such as automated port selection on the both entrance and exit, filter wheel drive capability, microstep motor, 2 or 7 mm, maximum slit aperture, dual array capability, tiltable flange accommodating to most array detectors, and single channel detectors as PMT, solid state detectors.
