For some medical and semiconductor applications, a (very) small tip is desirable to do reflectance measurements. Avantes offers two standard diameters of small tip reflection probes, 1.5 and 2.5 mm and each tip is normally 100 mm long.
The probe is configured with an illumination leg with six 200 μm fiber cables which connects to a fiber coupled light source and a single 200 μm read fiber cable to measure the reflection via connection to a spectrometer.
A special angled fiber holder (AFH-15) is available for the 1.5 mm diameter reflection probe. This device enables reflection measurements under angles of 15, 30, 45, 60, 75 and 90 degrees.
