Quality Assurance - Technicians in our Quality Assurance department are testing optical components using a scanning spectrophotometer. The instrument measures transmission values from near infrared through visible, and well into the far UV band. Both finished goods and raw material are tested. Precision Glass is a MIL-I-45208 facility.

Tool Maker's Microscope - A small part is measured in a tool makers microscope.

Annealing Ovens - PGPco has seven annealing ovens. Shown above is a programmable high temperature computer controlled oven with printer/plotter and digital read out capable of annealing of a wide variety of materials.

Blanchard Grinding - Our precision grinding department consists of Blanchard grinders, surface grinders, and Brown & Sharpe OD/ID grinders.

Quartz Fusing - A technician joins two quartz parts. PGP's proprietary fire-fusion process offers unique design opportunities since joined parts are virtually one piece with very minimal dimensional distortion.

CNC Jig Grinder - Capable of either rotary diamond grinding or ulatrasonic grinding. Accuracy of ±.0001 inches can be held with this machine. The table resolution is 20 microinches.

Optical Comparator - A technician checks sizes on an optical comparator.

Precision Management - A technician (left) makes rapid but accurate measurements on a CMM. Such equipment allows for much more reliable quality assurance at lower costs. Statistical process control can be implemented simultaneously through software. The technician in the foreground is optically measuring the radii of small spherical cavities, 36 per part, precision polished into a glass mold used for casting plastic components.

The Tool Room - Our 'tool room' not only provides our glass/quartz production departments with custom fixtures and special templates but has also filled orders of non-glass materials.
