Coatings:
AR Coating (Anti-Reflective Coating): 400 - 1000 nm. Effectively reduces stray light for superior imaging. Primarily used for projection lenses, camera lenses, and photographic lenses.
Laser Coating: 420 - 680 nm, Dual-band for 532 nm & 1064 nm. Withstands high-power laser irradiation without damage. The former (420-680nm) is mainly used for high-end laser projection; the latter (532/1064nm) is primarily used for medical equipment.
Super Hard Water-Repellent Coating: 400 - 900 nm. Features high abrasion resistance and strong hydrophobicity. Effectively reduces stray light for clear imaging. Mainly used for high-end surveillance lenses, automotive lenses, etc.
UV/IR Coatings: 400 - 700 nm. Cut-on/off wavelength T=50%, ±5 nm. Enhances transmission in desired wavebands while blocking unwanted ones. Primarily used for various waveband applications in equipment and instruments.
Note: Various specifications can be customized according to customer requirements.
