Coated monocrystalline silicon lenses for optical imaging Custom silicon components for optical lenses
A coated silicon lens is an optical element that is coated with a special film on the surface of a silicon lens to improve its optical performance. Silicon material has excellent light transmission in infrared band, but the surface reflectivity is high, through coating can effectively reduce the reflection loss, enhance the light transmittance, and improve the anti-reflection, anti-wear and other properties. Coated silicon lens is widely used in infrared optical system, laser technology, thermal imaging and other fields.
* Silicon material has excellent transmittance in the infrared band of 1.2-7μm, but the surface reflectivity is high (about 30%). By plating anti-reflection film (such as MgF₂, SiO₂, etc.), the reflectivity can be reduced to less than 1%, significantly improving the transmittance.
* Coated silicon lenses perform well in near-infrared (NIR), mid-infrared (MIR) and far-infrared (FIR) bands, suitable for multi-band optical systems.
* The coating design can be optimized for specific wavelengths or bands to reduce stray light interference and improve imaging quality.
* The silicon material itself has high hardness, and the coating further enhances the surface wear resistance and prolongs the service life.
* The thermal expansion coefficient of silicon is low, and the coating can still maintain stable performance in high temperature environment, suitable for high temperature application scenarios.
* Coating can improve the moisture resistance and corrosion resistance of silicon lens, adapt to harsh environment.
1. Coated silicon lenses are used in thermal imaging cameras to focus infrared radiation and generate clear thermal images, which are widely used in security monitoring, industrial testing and medical diagnosis.
2. In laser processing, communications and medical equipment, coated silicon lenses are used to focus and collimate laser beams, and coating can reduce energy loss and improve system efficiency.
3. In infrared spectroscopy and Fourier transform infrared spectroscopy (FTIR), coated silicon lenses are used to transmit and focus infrared light, ensuring high-precision spectral analysis.
4. In infrared detection systems for satellites, missiles and aircraft, coated silicon lenses are used for target detection and tracking, and their high light transmittance and thermal stability are key advantages.
5. In industrial infrared sensors and inspection equipment, coated silicon lenses are used for non-contact temperature measurement, gas analysis and material inspection.
6. In infrared optical experiments and research, coated silicon lenses are used to build optical systems to support high-precision experimental requirements.
1. Q: What is a coated silicon lens?
A: A coated silicon lens is a silicon-based optical component with a special thin film coating applied to its surface. The coating reduces reflection, enhances light transmission (especially in the infrared range), and improves durability, making it ideal for applications like thermal imaging and laser systems.
2. Q: Why are coated silicon lenses used in infrared applications?
A: Coated silicon lenses are used in infrared applications because silicon has excellent transparency in the 1.2-7μm range, and the coating minimizes reflection loss. This makes them highly efficient for thermal imaging, spectroscopy, and industrial sensing, especially in harsh environments.
