Overview: A modular prism based imaging spectrometer and spectrograph captures low signal- to-noise, spatially resolved spectra, at all wavelengths from 365-nm – 920-nm simultaneously.
When used with a CCD or CMOS camera spectrum detector it becomes an imaging spectrometer. Enables point-to point spectral imaging (see Figure 1).
Design: The PARISS imaging spectrograph and spectrometer uses a prism with curved sides to deliver state of the art light throughput efficiency. This enables highest sensitivity and very fast acquisition times, even with low signal to noise spectra. (See figure 2)
Zoom magnification is available from 1x to 40x, and more.

Macro-PARISS “kit:” Most PARISS modules are available separately. Our goal is to enable any researcher to mix-and-match and buy only what is needed. When budgets are squeezed this is a great way to save money.
Upgrade any time as funds become available.
Mounting: PARISS imaging spectrograph can be column mounted on a bench, a tripod, or interface with a microscope video port.
Light collection optics can include a c-mount macro lens, with or without zoom capabilities, a microscope objective or telescope optics.
Spectral object characterization in %Reflection, absorption, or luminescence
Spectral cameras: can be user supplied or select from a range of options available through LightForm.
Software: Written in Python, various options are available including:
- Basic spectral analysis %Refection, absorption, emission
- Spectral classification
- Create spectral libraries
- Perform spectral recognition (Figure 5)
