Back story! For years I dreamed about creating a camera that would give a 2 dimensional image of the pH of the seawater around a swimming animal. The idea was to be able to measure respiration rates of swimming zooplankton (when CO2 is excreted by the animal, it changes the pH of the seawater, and changes the color of a dissolved indicator dye I could add to the seawater). I wanted to measure how much energy it costs a 3mm long copepod to migrate from 600 meters deep in the ocean each night to the surface, and then swim back in the morning. That’s the equivalent of a person walking 45 miles to lunch and back each day! Back then, it wasn’t possible (so I created a numerical model of the swimming from high speed photography instead). But now, it is possible! Hyper-spectral – multi-spectral imaging is here, it’s effective, and it’s affordable! Imaging with spatial and spectral resolution – multi-spectral imaging with Pixelteq’s SpectroCam™ and PixelCam™ provides the spatial variation in chemical composition in qualitative and quantitative ways, optical properties, and other information that can be used in thousands of applications. Multi-spectral imaging is a faster, simpler version of hyper-spectral imaging. We offer two unique solutions:
- SpectroCam™ Multi-Spectral cameras that deliver a configurable hardware & software platform for application development and deployment using sequential video-rate imaging for up to 8 spectral bands at a time using interchangeable optical filters.
- PixelCam™ Multispectral Cameras that provide true snapshot multi-band imaging using a variety of area & linear sensors for application-specific cameras with small form factors and straightforward device integration.
Spectrocam Multispectral Wheel Cameras
SpectroCam™ multispectral wheel cameras offer a sophisticated, flexible platform for development and deployment of various imaging applications. Available in UV, VIS, and SWIR versions. Designed to reduce development times and simplify the design cycle, SpectroCam™ features a high speed, continuously rotating filter wheel containing 6-8 interchangeable optical filters. Combined with the scientific grade CCD array, this filter design creates a fully portable and configurable, high speed multi-spectral imaging system. With minimal pixel shift and high frame rates, the dynamic Spectrocam™ is a powerful product development tool. SpectroCam™ systems are available in a turnkey format complete with lens, eight interchangeable filters and acquisition software that can be used for innovative 2D spectroscopy research in a variety of fields including water quality measurement, product screening, machine vision, medical imaging, surveillance and authentication. The system can also be customized for integration into specific OEM products. The platform is readily modified to meet your mechanical and environmental needs. SpectroCam™ is available for R&D teams who need a quick, turnkey solution. The device utilizes a wideband CCD capable of UV-enhanced measurements and can be supplied with a standard set of filters or outfitted with up to eight different interchangeable custom filters. The proprietary design allows for quick delivery while providing a system that suits your specific application needs today and for years to come. The SpectroCam™ offers a cost-effective and versatile solution for your current and future multispectral imaging projects.

Spectrocam software provides command and control functions for the continuously rotating wheel, exposure controls for the camera, real time display of results, and saving of image data to files. The software also provides basic image processing algorithm loading and display of false colors to indicate results from those algorithms. Spectrocam is the ideal tool for developing multispectral applications as both filters and software are easily modified.
