Infrared Silicon Plano-Convex Lenses Product Overview

Infrared silicon plano-convex lenses are crafted from single-crystal silicon material, featuring one flat surface and one convex surface, specifically designed for focusing and collimating light. Coligh is a Chinese manufacturer of infrared plano-convex silicon lenses, capable of producing optical lenses with diameters up to 1000mm. In addition to cold-working infrared plano-convex lenses, we also offer coating services. These include, but are not limited to, infrared anti-reflective coatings and DLC coatings. We can customize surface profiles, focal lengths, and optical coatings based on customer drawings and application requirements.

Infrared Silicon Plano-Convex Lenses Characteristic

Silicon is one of the preferred materials in infrared optics.  It has features below:

• It exhibits a high refractive index in the infrared spectrum, allowing lenses to be manufactured with larger radii of curvature, resulting in thinner and lighter designs. Silicon demonstrates high transmittance across the 1.2-7 micron spectral range.
• With a Mohs hardness of 7, silicon possesses exceptional wear and scratch resistance due to this physical property.
• Silicon exhibits exceptional thermal stability, capable of sustained operation at temperatures up to 200°C.
• Furthermore, single-crystal silicon possesses high thermal conductivity and excellent heat dissipation properties, making it well-suited for high-power infrared laser systems.

Our Advantage Of Customizing Infrared Silicon Plano-Convex Lens

• We strictly select high-quality optical monocrystalline silicon as substrate material to ensure high consistency in material properties across batches.
• We process silicon lenses using single-point diamond turning machines and robotic grinding machines, enabling precise control over lens curvature radius, center thickness, and focal length.
• Our coatings undergo rigorous coating testing, and every lens shipped is inspected with an interferometer to ensure compliance with specifications.

Infrared Silicon Plano-Convex Lenses Applications

• Infrared Thermal Imaging
  Infrared thermal imaging systems require optical components with high transmittance to transmit infrared light. Silicon substrates exhibit excellent transmittance in the mid-infrared wavelength range. Silicon plano-convex lenses can be positioned in front of infrared detectors at the imaging location to converge and image infrared radiation, enhancing image brightness and resolution.
• Nd:YAG Laser
  Nd:YAG laser systems require beam focusing and collimation. Silicon plano-convex lenses can function as focusing elements, concentrating laser beams or collimating divergent beams onto detectors to enhance the energy concentration of the laser system.
• Infrared Communication
  Infrared communication requires beam collimation or focusing to ensure long-distance transmission and signal stability. Silicon plano-convex lenses can focus infrared beams into narrow beams or collect focused beams onto detectors, guaranteeing high-speed, stable infrared data transmission.
