The Optics div. of Spectral Products provides high precision laser-quality regular plane (≤5 arc min), extremely parallel plane (≤10 arc sec), and wedged (30±5 arc min) windows fabricated from UV fused silica or BK7. These windows are polished on both sides with high flatness and high surface quality to handle high power laser applications as well as various industrial applications.
They can be used as laser windows with a proper anti-reflection coating and can become various coated products, such as, plate beam splitters, dichroic filters, and partial reflectors.

NOTE:
-
Usually 0.5-2.0" diameter substrates are in stock. Please check up the delivery for the larger substrates with us. It usually takes ~3-5 weeks if we don't have any in stock.
- Some other sizes and/or thicknesses may be available. Please contact us for other custom size windows.
- Spectral Optics provides anti-reflection coating services on these windows. Please refer to our coating services, V-coating and Broadband anti-reflection coating for the details. Please contact Spectral Optics for the price.
- A custom substrate will need the fixture machining charge (~$200-400). The coating lot charge (~$400-800 per each lot) will be applied for a special wavelength.
