Frequently Asked Questions
How is Penn providing sapphire coatings? What is the most common type of coating used?
Sapphire coatings are done using ion-assisted deposition and plasma deposition techniques. Because of sapphire optics’ multispectral properties, this opens up more design possibilities. The most common type of sapphire coating is our anti-reflection coatings.
What sapphire optics does Penn commonly work with?
Penn mostly coats windows, but also some lenses. Windows are typically between 5mm – 10in, however, we can coat windows up to a 32 inch diameter.
What’s important to know when a customer is looking for a sapphire coating?
Firstly, we need details about the application. This includes if the optic is multispectral or extends across multiple applications.
