Fused silica laser protective windows are designed to provide a high level of protection for both equipment and individuals in laser-based applications.
These windows are constructed from fused silica, a high-purity amorphous silicon dioxide material, known for its excellent optical properties, high thermal resistance, and low coefficient of thermal expansion. Fused silica offers exceptional transmittance across a wide range of wavelengths, making it ideal for various laser systems.
The windows act as a barrier, safeguarding operators and equipment from potentially harmful laser emissions by absorbing, reflecting, or diffusing the laser energy.

I failed to process the payment via credit card, what should I do?
If you are having difficulty processing payment via credit card, there are a few steps you can take:
- Contact your credit card company: Verify with your credit card company whether the amount exceeds your spending limit and ensure that all payment activity is being authorized by you. It's also possible that your credit card company is experiencing technical difficulties or maintenance, which is preventing the payment from going through.
- Contact the merchant: In this case, you should contact the merchant (in this case, info@cloudray.com) immediately to inform them of the problem. The merchant can check if there are any issues on their end, and help you troubleshoot the problem.
- Use an alternative payment method: If the problem persists, you may want to consider using an alternative payment method, such as PayPal or bank transfer.
Remember to always exercise caution when making online purchases and to protect your personal and financial information.
