A 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 spectrometers give an average spectrum, where imaging spectrometer allows you to know the spectrum at different position inside the laser beam. Our MISS spectrometer gives you a two dimensions image, one dimension being the position in one diameter of the beam, the other is the spectrum at this position.
MISS stands for Mini Imaging Spatial Spectrometer. This innovative spectrometer gives access to the spatially resolved spectrum of your sources. Thanks to its unique compactness, the 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. Use it in free space mode to take benefit of the spatial resolution, or with a fiber input, like a regular spectrometer.

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.
Custom versions available on request.
|Enhanced detection||Replacement of the default camera embedded in the MISS by a higher performance one to increase the specifications of the system (better spectral and imaging resolution, single pulse extraction up to 150 kHz)|
|Fiber input connector||Plug&play fiber connector. Can be mounted on the MISS to easily switch the input from free-space to fiber and therefore us it as a standard spectrometer. No alignment required.|
|High dynamic range||Software mode to increase the dynamic of the MISS signal acquisition from 12 to 16 bits. Not compatible with pure single-shot measurement as 2 images are necessary to build one spatially resolved spectrum|
|Trigger||Synchronization of the MISS detection to an external signal for accurate laser single pulse extraction up to 75 kHz (150 kHz with the Enhanced detection option)|
