Our ability to engineer solutions to challenging applications has won Pacific Quartz, Inc. the loyalty of many customers in the solar and semiconductor industries. The gold coated quartz window shown here was designed for use in silicon crystal growing equipment. Machined from viewport quality flame-fused quartz, we have manufactured them in various sizes from 5" to 18" long. Polished and ground on two sides, these products feature a gold, infrared reflective coating. Formulated in collaboration with our coating partner, the mil-spec coating provides the durability needed to achieve a long service life in a high temperature environment.

Our impressive store of knowledge enabled us to add value to this project beyond what the customer initially expected. We have now been working with them on various projects for the past 25 years. If you are interested in learning more about this product, please contact us today.
