GEMINI Interferometer
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.
Main Features
- Rugged, robust, and insensitive to vibrations, thanks to our patented common-path geometry.
- Factory assembled and aligned for easy and turn-key integration in any existing setup, requiring no particular optical alignment procedure.
- Compact (176 x 44 x 54.5 mm) and lightweight (approx.400 gm)
- Broad spectral coverage from 400nm to 2300nm, with optional ultra-broadband coverage from 250 to 3500 nm.
- It provides continuous spectra, with a virtually unlimited number of spectral bands.
- High throughput: featuring a 1-cm clear aperture without any grating nor input/output aperture slits.
- Scan range and spectral resolution selectable by the user, who can start with quick measurements to have an initial look at the spectra, and then prolong the data acquisition to increase both the signal-to-noise ratio and the spectral resolution, down to <1 nm in the visible, see below.
- Drivers included, with intuitive examples and a complete user manual.
- Worldwide quick support.

It goes great with…
The GEMINI can be naturally coupled with the SPIDER Photodetector, to obtain a 320-1700 nm Spectrometer.
GEMINI-2D
Advanced GEMINI model, specially designed to:
keep constant the dispersion and keep fixed the absolute arrival time of one of the two replicas.
