SILIOS presents the unique TOUCAN Multispectral Snapshot Camera

Our partner SILIOS Technologies, a french high-tech company, recently announced the launch of its new snapshot multispectral camera, the TOUCAN. This multispectral camera is currently the only Multispectral Filter Array (MSFA) based camera available on the market with such a large covered spectral range (~450nm instead of less than 300nm for all other existing MSFA based cameras). The TOUCAN camera can thus address both VIS and NIR ranges (from 430nm up to 890nm).

SILIOS Technologies has been proposing snapshot multispectral cameras since 2016 with the CMS Series, based on a 1.3Mp CMOS sensor and since 2019 with the CMS4 Series, based on a 4.2Mp CMOS sensor. The SILIOS snapshot multispectral cameras are made by the hybridization of a pixelated multispectral filter (i.e. MSFA also called custom Bayer mosaic) onto a commercial CMOS sensor.


Each Series offers three models corresponding to three specific spectral ranges:

  1. the model C which addresses the range 430nm-700nm (VIS)

  2. the model V for the range 550nm-830nm

  3. the model S for the range 650nm-930nm (NIR)

Any of these snapshot multispectral cameras captures synchronously 9 different images centered on 8 spectral bands equally spaced in their respective spectral ranges, plus one panchromatic band (monochrome pixel).


The TOUCAN Camera is based on a 4.2Mp CMOS sensor and addresses the range 430nm - 890nm with 10 bands. This large spectral domain allows a wide range of applications due to a much stronger spectrum differentiation capability.

The TOUCAN camera is the ideal tool for number of applications in several domains such as precision agriculture, medical diagnostic, defense and security, industry, space, and many more.

Each SILIOS multispectral camera is delivered with COLOR SHADES Lab, an open Software Development Kit (SDK), coded in C++ and is supplied for free to get familiar with the camera, set it, acquire images/hypercubes or sequences of images/hypercubes, apply data correction and preliminary data treatment such as spectrum recognition for instance. COLOR SHADES Lab can be also useful as a help for the development of proprietary applications.
