Suitable for measuring color, the Torus concave grating miniature
spectrometers from BFI Optilas International SAS are visible-range (360 to 825 nm)
units that deliver stability and low stray light with optical bench throughput.
They provide increased sensitivity and throughput for low-level applications. The
concave grating improves their thermal stability. Wavelength drift is nearly eliminated,
and peak shape stays the same over a wide temperature range. The devices enable
precision metrology, fluorescence and absorbance applications with demanding stray
light and thermal stability requirements. Other applications include measurement
of trace gas amounts in the atmosphere, absorbance of optically dense solutions,
fluorescence from solid surfaces and backscattering/fluorescence in solutions and
powders, and LEDs, lasers and other light sources. The devices are also useful in
medical dosimetry in tissue and biological media.
