Price of an optical glass window
Pricing of an optical window is based on four main factors :
- Raw material, borosilicate window like a B270 window will be much cheaper that an IR window like germanium window.
- Quantities, usually polishing is done on big equipements that can handle simultaneously several parts in one batch, the more we arrange together the lower the cost.
- Polishing quality, the more the surface aspect request is high the highest the cost, the cost increase relation is closer to exponential than linear.
- Coating cost can also impact a lot the price of an optical window, especially if the optical coating is custom made for few parts only.
