Analyze in detail: What are the application scenarios for processing optical glass lenses?

This question is very accurate! The core application scene of processing optical glass lens covers many high-precision fields such as optical imaging, photoelectric display, precision measurement, etc. Its essence is to realize various optical functions by relying on its high light transmittance, high refractive index and stable optical performance.

Detailed analysis of core application scenarios

1. The field of imaging optics

Camera/photographic equipment: the lens group of SLR, micro-camera (including spherical mirror and aspherical mirror), aerial camera lens of unmanned aerial vehicle, and moving camera lens, which can correct chromatic aberration and distortion through the combination of multiple optical glass lenses and improve imaging clarity.

Security monitoring equipment: the infrared lens and zoom lens of the camera are monitored, and optical glass lenses are needed to ensure the imaging effect and remote monitoring accuracy in low illumination environment.

Medical imaging equipment: the optical lens of gastroscope and enteroscope, and the optical conductive parts of CT and nuclear magnetic resonance equipment require the lens to have biocompatibility and high light transmittance to ensure the accuracy of medical images.

2. The field of photoelectric display

Smart phone/tablet computer: the lens of mobile phone camera (front/rear multi-camera) and the optical lens of fingerprint identification module under the screen need ultra-small size and high wear-resistant optical glass, which is suitable for thin and light design.

Display panel matching: liquid crystal display (LCD), light guide plate of organic light emitting diode display (OLED), polarizer base glass, projection lens and beam splitter lens of projector to ensure uniform light transmission and color reproduction.

Virtual Reality (VR)/ Augmented Reality (AR) equipment: the immersion lens of VR head display and the optical waveguide lens of AR glasses need high refractive index glass to realize the optical effect of small volume and wide field of view.

3. The field of precision measurement and instruments

Industrial measuring instruments: optical lenses of laser rangefinders and coordinate measuring machines, beam splitting lenses and transmission lenses of spectrometers and interferometers. The lenses are required to have high flatness and low dispersion to ensure measurement accuracy.

Astronomical observation equipment: The primary mirror and secondary mirror of astronomical telescope are mostly made of large-size optical glass (such as fused Shi Ying glass), which needs to be polished precisely to capture the light from deep space celestial bodies.

Semiconductor equipment: mask aligner's optical projection system and microscope head of wafer inspection equipment rely on ultra-precision optical glass lenses to achieve nano-scale lithography accuracy and wafer defect detection.

4. Other special scenes

Automotive optical system: vehicle-mounted camera lens (ADAS advanced driver assistance system) and headlight lens, which need high-temperature and impact-resistant optical glass to adapt to complex working conditions of automobiles.

Optical communication equipment: optical isolators and optical glass lenses used in optical fiber communication to ensure low-loss transmission of optical signals.

Military defense field: the optical seeker and night vision lens of infrared guided missiles need special optical glass (such as infrared transparent glass) to meet the optical detection requirements in extreme environments.

Common demand of scene

All application scenarios have strict requirements on the processing accuracy (surface roughness, dimensional tolerance) and optical performance (transmittance, refractive index stability) of optical glass lenses, and special treatments (such as antireflection film, antireflection film and wear-resistant coating) need to be adapted according to the scene characteristics.
