GEMINI Interferometer
Broadband spectroscopy with high throughput
Broadband spectroscopy with high throughput
GEMINI is the ultimate interferometer providing unrivaled accuracy and reproducibility in controlling the temporal delay between the two replicas of the input light. It can be employed in combination with our included drivers and software to measure the spectrum of the input light (either coherent or incoherent source) based on the Fourier-transform approach, as in any FTIR spectrometer.

It goes great with…
The GEMINI can be naturally coupled with the SPIDER Photodetector, to obtain a 320-1700 nm Spectrometer.
Specifications can be subject to change without notice.
