Plano-Convex Lens, Si, AR Coating T10: 2000-5000 nm OLC241332-T10
This JCOPTIX plano-convex lens is made from single-crystal silicon (Si), a common core substrate for mid- and long-wave infrared systems. It supports highly transmitting infrared imaging and laser delivery, with excellent heat conduction to suppress irradiation-induced thermal distortion and thermal lensing during prolonged, stable high-power continuous mid-infrared operation. Its moderate infrared refractive index provides stable, uniform optical performance across the core 2.0-5.0 μm range. Excellent mechanical strength and deformation resistance, lower density than conventional infrared materials, and strong thermal stability support lightweight designs and demanding infrared paths under temperature changes. JCOPTIX offers diameters of 12.7-25.4 mm with antireflection coatings for 2000-5000 nm. Average reflection below 1.25% per surface improves transmission.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
