qpod

Customizable temperature-controlled sample compartment for use with fiber optic spectrometers
Product Overview

The qpod is a compact spectrometer sample compartment containing a cuvette holder temperature controlled by an external TC 1/Single Temperature Controller. The qpod is a roughly square box about 120 mm on a side and 90 mm high. In the center is a temperature-controlled tower with optical ports on each of four sides and slit holders to control optical access. For mounting optical components, each of the four sides of the qpod has a mounting ring, thermally stable and precisely aligned with the tower. Add light sources, lenses, filters, polarizers, mirrors, spectrographs and detectors as needed for your experiment. Most applications of the qpod take advantage of fiber optics for transmitting light, but lasers, focused light sources and probes of various kinds may be used. A dry gas purge of the compartment enables easy use at low temperatures down to below -30 °C. The standard qpod readily achieves a high temperature of +110 °C. Purchase the extended temperature option to go higher to +150 degrees. Operate the qpod on a lab bench or build it into your own full spectroscopy system. For computer control, add program T-App or write your own program utilizing simple text commands to control the TC 1/Single Temperature Controller.
