15mm Sapphire Lens with Anti-Reflection (AR) Coating – 3mm Thickness
Description
The SL15-3PE Sapphire Lens is a high-performance optical component designed for demanding applications that require superior durability, chemical resistance, and broad spectral transmission.
Made from optical-grade single-crystal sapphire, this 15.0mm diameter, 3.0mm thick lens offers excellent optical clarity across UV, visible, and infrared wavelengths (0.15–5.5µm).
The anti-reflection (AR) coating enhances transmission, achieving >90% efficiency in the 610–1200nm range, reducing reflection losses for high-precision optical systems. With extreme hardness (Mohs 9), exceptional thermal stability, and resistance to abrasion, high pressures, and harsh chemicals, this lens is ideal for use in laser optics, infrared imaging, aerospace, and industrial applications.
