Imaging Spectrometers

A spectrally resolved image of a slit positioned along the length of a mercury spectral lamp. As can be seen, intensity and spectral variations exist along the lamp. |
Imaging Spectrometers enable the acquisition of a spectrally resolved image of a two dimensional scene. P&P Optica imaging spectrometers are designed to allow simultaneous collection of data along the length of a thin slit. As the slit scans across a scene, multiple images are taken to stitch together a hyperspectral image. The advantage of such system is that all spectral data for a given point is collected at one time, and it provides very highly spectrally resolved images (down to 0.3nm resolution). Furthermore, with the exceptional optical design, P&P Optica's imaging spectrometers also provide excellent spatial resolution determined by the pixel size of the detector used.
P&P Optica imaging spectrometers can be easily adapted to fit most standard microscopes. This can be done by either attaching the spectrometer to a camera port using our C-mount adaptor, or by attaching fiber optic input to an SMA port available on many microscopes. When combined with a scanning stage, hyperspectral images can be obtained.
