Vernier Spectrum Tube Single Power Supply User Manual

Spectrum Tube—Single Power Supply

(Order Code ST-SPS)

Introduction

The Vernier Spectrum Tube Single Power Supply offers a considerable improvement in safety, convenience, and tube
life over conventional systems. It consists of a power supply, a tube storage unit, and a series of spectrum tubes filled
with various gases for spectral inspection and measurement.

The system is available in two versions, differing in the style of the power supply and storage unit. In the Single Tube
version, the power supply accommodates one tube and provision is made in the base for storage of up to six tubes. In
the Carousel version, up to eight tubes are loaded into the power supply’s tube carousel and the tube to be energized is
selected by rotating the carousel until the required tube reaches the energizing station.

The spectrum tubes in the Spectrum Tube System offer extended life by having no internal electrodes and are
protected against accidental breakage by a hard polymer shell. The Single Tube Power Supply’s electrical parts are
enclosed and a magnetic interlock system prevents application of the energizing voltage to the tube contacts unless a
tube is correctly inserted. The height of the tube above the bench can be adjusted to accommodate the differing heights
of the inlet slits of the various models of spectrometer in current use.

Fiber Holder

The Fiber Holder for the Spectrum Tube Single Power Supply securely holds an
optical fiber in the proper position to carry light from the discharge tube to the
spectrometer. Compatible with both Ocean Optics fibers and Vernier SpectroVis
series fibers. The position of the fiber can be adjusted to optimize the light
intensity. The Spectrum Tube Single Power Supply ships with one Fiber Holder.
Additional holders can be purchased.
