MISS 2D spectrometer
Acquire spatially-resolved spectrum of laser beams
MISS (Mini Imaging Spatial Spectrometer) gives access to the spatially-resolved (2D) spectrum of laser beams. Thanks to its unique compactness, MISS allows vertical and horizontal spatial chirp measurements at any position of your beam path. It can easily be integrated at different stages of amplified laser systems. It can be used in free-space mode to take benefit of the spatial resolution, or conveniently with a fiber input, like a regular spectrometer (plug & play SMA fiber connector included).
Ultra-compact and robust

2D spectrum characterization for many common types of lasers
A conventional spectrometer allows you to know the spectrum for your laser, i.e. the intensity of each wavelength (or frequency) present in your laser. Most of regular spectrometers give an average spectrum (1D), where imaging spectrometer allows you to know the spectrum at different positions along the laser beam cross-section (2D).
Our MISS spectrometer gives you a two dimensions image, one dimension being the position in one diameter of the beam, the other being the spectrum at this position.
2D imaging spectrometers therefore perform a spatially resolved spectral characterization of lasers, which is very helpful for investigation of spatio-spectral couplings such as the spatial chirp usually induced in the compressor stages of ultrafast lasers or during the amplification stage of broadband spectrum.
Product reviews
Product reviews
The MISS-Broadband-L was acquired as a test device to extend our high-energy pulse metrology capabilities. Thanks to its performance, ease of use, and the company’s support in integrating the imaging spectrometer with our in-house developed code, it is now the central element of our spatio-spectral characterisation, such as compressor alignment or spatio-temporal measurements.

Our MISS-Broadband-L and MISS-VSWIR imaging spectrometers are extremely useful to diagnose our few-cycle light sources, even after post-compression. The spatio-spectral resolution allows to check the pulse quality both in near and far field, that gives an unmatched performance for measuring the spatio-spectral distortions of ultrashort pulses.

Our MISS imaging spectrometer is very easy to use and much more compact than the other similar systems we have in our group. I also appreciate the very quick support from the team.

1 Resolution achieved on the highest resolved part of the spectral range
2 Due to rolling shutter, the actual minimum exposure time to properly capture the whole beam will be limited by the laser beam size (in case of single-shot measurement) or by the laser repetition rate. For single-shot measurement : the larger the beam, the longer the required minimum exposure time. Otherwise, the slower the repetition rate, the longer the required minimum exposure time.
