BFi OPTiLAS’ Announces Concave Grating Mini-Spectrometers

The Torus Miniature Spectrometer is a Visible range (360-825 nm) unit that delivers low stray light and is ideal for measuring color. Its increased sensitivity and throughput also make is perfect for low light level applications. The concave grating helps to improve thermal stability of the Torus. Wavelength drift is nearly eliminated and peak shape stays the same over a wide temperature range.

As a result, Torus makes possible precision metrology, fluorescence and absorbance applications with demanding stray light and thermal stability requirements. Torus is the perfect solution for a wide range of applications where low stray light, high throughput and thermal stability are necessary:
  • Trace gas amounts in the atmosphere
  • Absorbance of optically dense solutions
  • Precision measurement of LEDs, lasers and other light sources
  • Medical dosimetry in tissue and biological media
  • Fluorescence from solid surfaces and backscattering/fluorescence in solutions and powders
