Benchmark™ Baseplate Compatible Accessory Polariser Rotator
Mount P/N GS12510
In place of the GS12000 Series polariser, a specific Benchmark™
baseplate compatible accessory polariser rotator mount can be fitted to
the aperture ports (
10 ) of the Silver Gate™ optical unit.
The polarizer mount GS12510 is a
rotatable mount that accepts the
Specac range of GS57010 Series,
38mm circular aperture, ring
mounted polarizers. When a
GS50710 Series polarizer has
been installed into the GS12510
mount, it can be rotated for a
particular angular degree of
polarized light by adjustment of an
outer rotating ring on the polarizer
mount itself.
Figure 8. GS12510 Polarizer Mount
The polarizer mount GS12510 can be used when polarized light
experimentation is to be carried out using any Benchmark™ baseplate
compatible accessory, particularly if there is limited space within a
spectrometer sample compartment. The standard aperture ports of the
Benchmark™ baseplate compatible optical units (as item
10 for the
Silver Gate™ optical unit), will accept a GS12000 Series polarizer. To
rotate this type of polarizer, it must be removed from the aperture port
and turned to align with the indicating grooves in the aperture port ring
for either parallel or perpendicular polarization and then re-inserted.
There is a risk of marking the polarizer substrate from fingerprints etc,
whenever placing the polarizer into, or removing it, from the aperture
mounting ports. Therefore, if continual changing of the polarizer
angular orientation is required, use of an appropriate GS57010 Series
polarizer within the GS12510 mount may help to minimize any risk of
marking/damage if using a GS12000 Series polarizer that has to be
removed from the aperture port and rotated by hand.
