Other Specifications - Quantum qpod 2e Instruction Manual

Probe Temperature Range. The qpod 2e accepts
standard 400 and 500 Series thermistor probes.
These probes may be obtained from laboratory
supply companies such as Cole Parmer
(coleparmer.com). Standard 400 Series
temperature probes will measure the temperature
within ±0.2 °C over the range of 0.0 to 70.0 °C. The
probe will operate over the full range of -40 °C to
+105 °C, but an individual probe will need to be
calibrated by the user outside of the 0.0 to 70.0 °C
range. The 500 Series probes are less standardized
and may require calibration by the user. 500 Series
probes may be convenient, because they are
available in very small diameters.

Other Specifications

Cuvette size. The qpod accepts standard cuvettes
with an outside dimension of 12.5 x 12.5 mm. The
center of the optical beam in the cuvette is 8.5 mm
from the bottom surface of the cuvette. Thus, for
Figure 5. The optical slits provided with the qpod 2e
some kinds of cuvettes it is necessary to specify
this standard z height.
Lenses. Collimating optics use a single 6 mm
diameter, 12 mm focal length lens. Imaging optics
use a pair of 12.5 mm diameter, 30 mm focal
length lenses with their convex surfaces nearly
touching. All lenses are fused silica and have a
broadband AR coating to reduce reflections
throughout the UV and visible spectrum.
Collimating lenses create a beam of parallel rays
with a diameter of about 4 - 6 mm. Imaging optics
focus and image of the end of a fiber into the
middle of the cuvette with a magnification of about
1, or focus light from a region of the cuvette to the
end of a collection fiber.
Optional Optical Filters. 1-inch (or 25 mm)
diameter filters may be propped up between the
lens assembly ant the cuvette holder. ½-inch
diameter lenses may be mounted on the lens
assemblies using the optional QFH filter holder.
