Custom sapphire windows

XKH can customize sapphire panels based on customers’ requirements for size and shape, as well as product thickness. Regarding some key points for customizing sapphire windows, we need to remind you of the following:

In terms of surface treatment, you don’t need to worry. The new course will have a very successful experience. For the polishing of sapphire wafers, single-sided polishing or double-sided polishing without polishing can meet your different requirements.
So in terms of customization, when you choose optics and polishing, we can achieve relatively high transmittance, and precision laser applications can also be achieved, with a surface roughness below 10, which is a very good phenomenon.

The most conventional type of polishing can achieve a roughness of less than 50, which is a relatively low-cost polishing process. Some wafers have very uneven surfaces with no gloss, and for applications where surface finish is not as important, unpolished surfaces can be chosen.

  What’s the delivery time of custom sapphire windows ?
A: For the standard products
For inventory: the delivery is 5 workdays after you place the order.
For customized products: the delivery is 2 or 21 days after you place the order.
 For the special-shaped products, the delivery is 28days after you place the order.

Usually, we apply sapphire windows to sensor infrared optical laser systems because sapphire has strong scratch resistance, making it suitable for high-power laser optical devices.
