Silicon IR Window FAQ

1. Can you produce custom non‑standard silicon window shapes?

Yes. We support CNC fully customized round, square, rectangular, stepped and special irregular silicon optical windows.

2. What coating is best for MWIR thermal systems?

MWIR anti‑reflection coating greatly improves transmittance. DLC coating enhances surface hardness and scratch resistance for harsh industrial environments.

3. Do you support small batch prototype orders?

Yes. We provide professional prototype verification service for new product R&D projects, supporting 5–50 pcs small‑batch trial production.
