This photograph of an experimental quartz chamber, clearly demonstrates Precision Glass Products' unique manufacturing capabilities. This remarkable device, produced in small quantities under contract to NASA, requires a high level of expertise in several quartz (or glass) fabrication technologies:
Precision Grinding of part geometry to ±0.0001
Assembly of individual quartz parts by fusion bonding with no loss of accuracy. Hermetic encapsulation of a metal core within a quartz cylinder. The quartz chamber was produced for microgravity research experiments being conducted by NASA. Dubbed the Isothermal Dendritic Growth Experiment, or IDGE, these chambers are to be used to observe and record dendritic growth in materials under weightless conditions (aboard the space shuttle.) More information concerning IDGE can be obtained at http://www.rpi.edu/locker/56/000756. An E-mail address is also available at IDGE@rpi.edu.
The chamber, constructed from 15 separately generated synthetic quartz components (and one metal piece), has many unusual features. The large main housing is precision ground from a single piece of high grade material and then optically polished on several of its exterior as well as interior surfaces. Four holes are bored through the housing and honed to a high degree of accuracy and finish. These are used to provide access to the interior for the following attachments:
The four attachments are then thermally bonded to the main housing of the chamber. These bonds are accomplished under rigidly controlled conditions of heat and pressure and result in virtually no loss of optical properties or deformation of part geometry. After fine annealing, the final product is essentially a single piece of quartz. Optical windows are then frit bonded to the remaining open sides of the chamber.
