SQUARE OPTICAL MIRRORS

Our square optical mirrors are made from BOROFLOAT® 33, which offers a low thermal expansion, high thermal resistance, and excellent chemical durability. Advanced Optics in-stock square optical mirrors are polished to λ/4 and coated with a robust AlSiO (protected Al) coating. In addition, we offer coatings to meet specific spectral requirements, including bare Al, enhanced Al, silver, and bare and protected gold.

Many of our square optical mirrors are available in stock for immediate shipment. See a list of our optical mirrors below:
