Short Focal Length Triple Grating Imaging Spectrographs
The TRIAX series use 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 such as:
There is a wide selection of gratings to choose from depending on optical requirements. Gratings are 32 x 32 mm for the MicroHR. There are three different types of gratings available; classically ruled, holographic, and blazed holographic. There is also a flat mirror that may be ordered for the dual grating turret option. Please click on the link below to view all our grating options.
In addition to wavelength control the Triax Series has an optional automated turret control and automated control of the optional internal five position filter wheel. There are multiple software platforms to choose from for spectrometer control and acquisition. Please click on the link below to view all our software choices.
The Triax Series is compatible with many optical accessories to create your custom solution. Please click on the link below to view some of our optical accessories.
