45° Incidence High-Reflection Round Optical First Surface Enhanced Aluminum Mirror

Description

45° Incidence High-Reflection Round Optical First Surface Mirror with Enhanced Aluminum

Premium-grade optical mirrors designed for precision beam steering, alignment, and reflection in laser systems and optical setups. These first surface mirrors feature enhanced aluminum coatings deposited directly on the front surface (no secondary reflection), ensuring maximum reflectivity (>90% across UV-VIS-NIR spectra) at a 45° angle of incidence. The robust aluminum coating is protected by a dielectric SiO2 layer, enhancing durability, humidity resistance, and longevity in demanding environments.

Key Features:

• Optimized for 45° Angle: Engineered for high-efficiency reflection at 45° incidence, minimizing beam deviation and energy loss.
• Enhanced Aluminum Coating: Delivers broad-spectrum reflectivity (250–2000nm) with superior performance in UV, visible, and near-infrared regions.
• First Surface Design: Eliminates ghosting and secondary reflections by placing the reflective layer on the front surface of the substrate (e.g., BK7, fused silica).
• Durable Construction: Resists abrasion, oxidation, and environmental degradation for reliable operation in industrial or laboratory settings.
• Precision Polishing: λ/4 surface flatness ensures minimal wavefront distortion for high-precision optical systems.

Applications:

• Laser beam steering, folding, and alignment in industrial, medical, or research lasers
• Spectroscopy, interferometry, and optical instrumentation
• Defense, aerospace, and telecommunications systems
• High-power laser setups requiring stable, low-loss mirrors

Available in custom diameters, thicknesses, and substrate materials (upon request). Ideal for applications demanding high reflectivity, angular accuracy, and environmental resilience.
