First Surface Aluminum Mirrors (Front Surface Mirrors)
First surface aluminum mirrors (also known as front surface mirrors or optical Al mirrors) feature a metallic reflection layer vacuum-deposited directly on the outer surface of an optical glass substrate, eliminating secondary surface ghosting and chromatic aberration inherent in standard back-coated mirrors (such as residential or bathroom glass mirrors).
Functions:
Delivers high broadband reflectivity across the ultraviolet, visible, and near-infrared spectral regions (200 nm – 2000 nm). Coated with durable dielectric protective layers (such as SiO2 or MgF2) via vacuum deposition to prevent aluminum oxidation, enhance mechanical scratch resistance, and maintain optical stability in high-humidity or industrial environments.
Applications:
Flight simulators
Optical projection units
Scientific imaging systems
Document copiers and scanners
High-resolution barcode scanners
Precision laser processing equipment
Automated Optical Inspection (AOI) machine vision systems

Information and Notes
1. Custom optical thin-film coating services on customer-supplied glass, fused silica, or optical substrates are available to support OEM/ODM system requirements.
2. Multilayer dielectric thin films (such as SiO2 or MgF2) are vacuum-deposited over the precision aluminum reflection layer to act as an environmental protective coat, preventing metal oxidation, improving mechanical scratch resistance, and ensuring long-term durability.
3. Coating processes utilize high-vacuum Physical Vapor Deposition with Electron Beam Gun Evaporation (PVD-EBGE) technology, ensuring exceptional film density, high adhesion strength, and precise spectral uniformity.
4. Reflectivity measurements represent values at normal or specified design angles of incidence. First surface reflection eliminates secondary surface ghosting for high-resolution optical alignment and imaging.
5. Dimension abbreviations: "Dia." or "Ø" denotes circular outer diameter.
