Fiber Optik Prob
Hellma Fibre Optic Probe-ATR Probe
ATR Probes
ATR means “Attenuated Total Reflection”. Light passing from a material with high refractive index (ATR crystal) to a material with lower refractive index (solution) is normally totally reflected. However, in practise, the light partially enters the solution and can be absorbed. The reflected light is therefore attenuated, causing a measurable reduction in the output signal dependent upon the absorbance of the solution.
