For some medical and semiconductor applications, a small/very small tip is advisable for conducting reflectance measurements. Avantes offers two standard diameters of small-tip reflection probes: 1.5 and 2.5mm, with each tip generally being 100mm in length.

The probe is configured with an illumination leg with six 200 μm fibre cables which connects to a fibre-coupled light source and a single 200 μm read fibre cable to measure the reflection via connection to a spectrometer.

A special angled fibre holder (AFH-15) is available for the 1.5mm diameter reflection probe. This device enables reflection measurements under angles of 15, 30, 45, 60, 75, and 90 degrees.
