The Benefits of our Miniature Spectrometer

Miniature Spectrometer

The MSP1000 miniature spectrometer (MiniSpec) is a compact, fibre-coupled spectrometer suitable for common laboratory tasks. By using the latest manufacturing techniques, we can provide the system for under £1000.

Whilst some low-cost spectrometers suffer from excess light which interferes with the ability to make measurements, our Miniature spectrometer features a Charge Charge Coupled Device (CCD) as standard, and as a result, does not exhibit significant etaloning.

We provide a free software toolkit for acquiring spectra and performing simple analyses such as peak detection, averaging, and smoothing. Users can export spectra as CSV files for processing with other numerical analysis packages.

Miniature Spectrometer

Designed to be a workhorse instrument for making quick and convenient measurements in the lab, the MiniSpec is easy to use.

By using additive manufacturing processes (3D printing) to build this spectrometer, we can provide the system at significant cost-saving over other similar instruments without compromising performance. This makes the MiniSpec affordable and accessible for users such as hobbyists, amateur scientists and astronomers, and educators at all levels from high schools to undergraduate labs.

Our MiniSpec has been used in local schools and colleges, by astronomy clubs, and by agricultural users interested in understanding their growth lights for fruit and vegetable characterisation and classification.

Applications include:
  • Light characterisation
  • Reflectance measurements for quality assurance or identification
  • Fluid absorption measurements
  • Monitoring paint pigments
  • Remote spectral monitoring
