Key Features

High-Precision Spherical Surface: Excellent surface quality, typically reaching 20/10 or better. Minimal spherical deviation, with sphericity error less than 0.001 mm, ensuring efficient light focusing. Diverse Material Options: Available in high-refractive-index materials, such as BK7, fused silica, sapphire, and LaSFN9, to meet different wavelength requirements. Quartz ball lenses offer high-temperature resistance and UV stability, while sapphire lenses are ideal for applications requiring greater mechanical strength. Wide Wavelength Range: Suitable for optical applications from ultraviolet (UV) to infrared (IR), covering wavelengths from 190 nm to 2000 nm. High Transmission Rate: Anti-reflection (AR) coatings reduce reflection losses and enhance transmission efficiency. Custom AR coatings can be applied for specific wavelength ranges (e.g., 400-700 nm or 1310/1550 nm).
