1 Introduction to the Variable Wavelength Detector
Optical System Overview

Lamp

The light source for the UV wavelength range is a deuterium lamp. As a result of
plasma discharge in a low pressure deuterium gas, the lamp emits light over the
190 – 600 nm wavelength range.
The lamp has an integrated RFID tag that contains the lamp specific information
(e.g. part number, burn time, ...). An RFID tag reader reads out this information
and transfers it to the user interface.

Source Lens Assembly

The source lens receives the light from the deuterium lamp and focuses it onto
the entrance slit.

Entrance Slit Assembly

The entrance slit assembly has an exchangeable slit. The standard one has a
1-mm slit. For replacement and calibration purposes to optimize the alignment, a
slit with a hole is needed.
