The function of coated optical glass

2026 05/26

The core function of coated optical glass is to regulate its optical properties through surface coating, optimize its light performance, and meet the professional needs of different scenarios. ‌
Improve transparency and reduce reflection glare
By coating an anti reflective film, the reflectivity of the glass surface can be significantly reduced, increasing the glass transmittance from about 96% without coating to over 99.5%. This can effectively reduce glare and stray light, making imaging clearer and brighter. It is widely used in optical equipment such as camera lenses, telescopes, microscopes, etc.
Regulating thermal radiation to achieve energy-saving and thermal insulation
Heat reflective coated glass can reflect infrared rays, block solar thermal radiation from entering indoor/car interiors, lower temperatures by 5-10 ℃ in summer, and reduce air conditioning energy consumption; Low-E coated glass can block indoor heat from radiating outward, reduce heat loss in winter, and meet the energy-saving needs of different regions in the north and south.
Protection and safety enhancement
Block over 90% of ultraviolet rays, prevent furniture and fabrics from fading, and protect human skin from UV damage;
The coating layer can enhance the surface hardness of the glass, resist scratches, acid and alkali erosion, and extend the service life of the glass; After coating the front gear of the car, rainwater quickly slides off in rainy weather, reducing fog condensation and improving driving safety.
Realize special optical functions
Different functional coatings can achieve diverse optical effects: high reflective coatings can be used for mirrors and solar panels to improve reflection efficiency; Conductive coating can be used in scenarios such as glass heating defrosting and LCD display screens; Special coloring/spectral coating can meet professional optical needs such as filtering, spectral analysis, and color adjustment.
