The Gemini 180 is a fully automated, double additive grating scanning monochromator. The incorporation of toroidal optics provides for optimum throughput and spectral resolution. The Gemini 180 functions as a high power, high purity light source for Fluorescence, detector characterization, and microscope illumination when coupled with one of our Xe Light Sources. It is ideal for applications that require low stray light such as:
There is a wide selection of gratings to choose from depending on optical requirements. Gratings are 50 mm x 50 mm for the Gemini 180. 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 Gemini 180 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.
