Introduction
Overview
The Stage-RTL-T is a novel sampling system for analysis of substrate materials such as silicon, metals,
glass and plastics. This stage system couples to our spectrometers and light sources, and can be
configured in a variety of setups for transmission and reflection measurements.
The STAGE-RTL-T is remarkably versatile: perform reflection measurements with the probe positioned
above or below the sample (measuring from below maintains a constant distance between probe and
sample); make reflection measurements with the light trap in place; or measure transmission of samples
using two fibers.
The Stage-RTL-T consists of a variable rail attached to a base plate, with three devices that attach to the
rail with a thumbscrew. From bottom to top, these devices are a fiber holder with UV-VIS collimating
lens; a sample holder for reflection or transmission; and a light trap to mitigate the effects of back
reflection and ambient light. (Remove the light trap to access a second collimating lens.)
