How the RSS-VA Works
The RSS-VA features a unique internal design that enables it to obtain sample measurements at
varying Angles Of Incidence (AOI). The RSS-VA works as follows:
Light enters the RSS-VA via the SMA 905 input connector (1).
1. Light is reflected up onto the sample port (2) at the degree determined by the AOI setting on
the RSS-VA, where it interacts with the sample.
2. Sampled light is reflected back down through the RSS-VA.
3. Light exits the RSS-VA via the SMA 905 exit connector (3).
Assembling the Hardware
You must first configure your sampling hardware and the RSS-VA prior to measuring your sample.
► Procedure
Follow the steps below to set up the RSS-VA:
1. Connect a fiber from the light source to the SMA 905 input connector of the RSS-VA.
2. Connect a fiber from the SMA 905 output connector of the RSS-VA to the spectrometer.
3. Place a STAN-SSH standard on the sample port.
4. Start your spectrometer operating software. Once data acquisition begins, a typical bell-
shaped curve should be displayed in the graph area.
5. Adjust the position of the slide carrier on the RSS-VA until the pointer on the RSS-VA is at
the desired AOI.
6. Adjust the integration time in the software until the signal peaks at approximately 3500
counts.
You have now properly configured the RSS-VA hardware.
