Enhanced Aluminum Mirror
Enhanced Aluminum Mirrors are designed for improved broadband reflection across customer-specified UV, visible and near-infrared bands—not for UV-only optimization. Chenyu Optics manufactures these mirrors on BK7 or fused silica substrates, with coating performance defined by the required wavelength band, angle of incidence and acceptance criterion. Surface accuracy up to λ/10 at 633 nm and 20-10 or 40-20 scratch-dig are available for drawing-based production.
Enhanced Aluminum Mirror Overview
Enhanced Aluminum Mirrors are precision optical mirrors using an aluminum reflective coating with protective enhancement layers to improve reflectivity and durability across a broad wavelength range.
Compared with standard aluminum mirrors, enhanced aluminum coatings provide higher reflectance and improved environmental stability, making them suitable for UV, visible and near-infrared optical systems where consistent broadband performance is required.
Chenyu Optics supports custom enhanced aluminum mirror manufacturing according to customer drawings, including custom substrate material, dimensions, surface accuracy and coating design for prototype and repeat production.
Key Advantages of Enhanced Aluminum Mirror
