Reflection Probes with Small Tips
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.
Depending on the application requirements Avantes offers a variety of jacketing options including Kevlar reinforced PVC sleeving with PTFE inner tubing (Standard), heavy industrial chrome plated brass mono-coil, stainless steel (BX), silicone coated stainless steel mono-coil (MS), flexible chrome-plated brass outer jacket with hooked profile (ME) and other special jacketings upon request. For applications requiring high-temperature resistance, special high-temperature epoxy (HT) is available and should be specified at the time of order.
