MISS spectrometer

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.
