Our Silicon Half Ball Lens offers excellent transmission from the NIR to mid-infrared range, making it ideal for IR imaging, sensing, and laser applications. With high refractive index and precise surface quality, these lenses provide superior focusing performance in compact optical systems. Custom sizes, coatings, and tolerances are available. Material: silicon Diameter: 15mm A silicon half ball lens is a compact infrared optical element designed for focusing, collimating, or coupling light in the near-infrared and mid-infrared spectrum. This type of silicon hemispherical lens offers a high refractive index and excellent thermal stability, making it suitable for small optical modules and IR sensing systems. 2. How Does a Silicon Hemispherical Lens Work?A silicon half-ball optical lens bends incoming IR light through its spherical geometry. Because silicon has high transmission in the NIR–MIR range, the lens can efficiently guide light into detectors, fibers, and imaging sensors with minimal loss. 7. People Also Ask (FAQ) Q1: Is a silicon half-ball lens suitable for infrared systems?Yes. Silicon offers excellent transmission in the 1.2–7µm range, making it ideal for most IR imaging and sensing applications. Q2: What is the difference between a half ball lens and a full ball lens?A half-ball lens has one flat surface and one spherical surface, making it easier to mount and integrate into compact devices. Q3: Can the silicon hemispherical lens be customized?Absolutely. Diameter, coating, surface accuracy, and tolerances can be fully customized according to your project needs. Q4: Why use silicon instead of glass for IR optics?Silicon performs better in infrared wavelengths, has a higher refractive index, and offers greater durability and thermal resistance. Q5: What coatings are available for silicon half ball lenses?Common options include NIR AR coating, MIR AR coating, and customized multilayer coatings.
