Metallized Mirrors

Round Metallized Mirrors

• High reflectance over entire visible and near-IR spectrum
• Aluminum is over-coated with MgF₂ for high durability
• The ideal mirror for most non-critical applications
• Available with /4, /10 and /20 surface flatness
• /20 substrates are synthetic quartz or Zerodur^® for high thermal stability
• Standard diameters from 5.0mm to 152.4mm

Aluminum has a high reflectance over the entire visible and near infrared spectrum (see curve). It is simple to deposit as a thin film, making it the ideal choice for most non-critical applications. The aluminum is over-coated with a single layer of MgF2 to make it considerably more durable than bare aluminum. There are three degrees of flatness: /4, /10 and /20. The /4 and /10 mirrors are deposited on BK7 substrates but the /20 mirrors use synthetic quartz resulting in significantly better thermal stability. A broad selection of sizes is offered as standard. Other sizes can be supplied on request. Please call with your inquiry. Mirrors up to 1 inch in diameter have a ground rear surface but all other mirrors are polished on the rear face.
