qpod/MPKIT

The qpod/MPKIT combines the qpod sample compartment with a full set of lenses and spherical mirrors that may be configured in multiple ways to measure both absorbance and fluorescence of a temperature-controlled solution. The optical package includes two collimating lenses, two imaging lenses and two spherical mirrors. 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. Place your sample in a cuvette in the central tower. Each of the four sides of the qpod has a mounting ring for optical components, thermally stable and precisely aligned with the tower. Place optics as needed. A collimating lens will create a collimated light beam of about 5 mm in diameter and pass it through the cuvette, or will take a 5 mm collimated beam and focus it onto another fiber. An imaging lens will focus the end of a fiber into the middle of the cuvette, or focus a section of the illuminated volume onto another fiber, using a magnification of about one. Spherical mirrors will focus any light emanating from the center of the cuvette back on itself, thus nearly doubling incident or emitted light. 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 +110 °C. Purchase the extended temperature option to go 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 Temperature Controller.
