As a professional glass coating manufacturer, we specialize in providing optical coating services on a wide range of glass substrates. With both raw material supply and precision processing capabilities, we deliver custom optical coating solutions for semiconductors, photonics, life sciences, and advanced display applications. Our expertise in optical thin film coating ensures that every component meets the strictest optical and mechanical standards.
Types of Optical Coatings We Provide
1. Anti-Reflective (AR) Coating
Reduces surface reflection and increases transmission.
Used widely in:
– glass wafers
– camera and sensor windows
– medical imaging optics
– scientific instruments
We tune AR coatings for VIS / NIR / specific laser wavelengths.
2. UV / IR Cut & Bandpass Filter Coatings
Designed for applications that require selective wavelength control:
– spectroscopy
– machine vision
– environmental detection
– LED/laser systems
Film stacks are engineered based on your spectral targets.
3. Dichroic and Beamsplitter Coatings
For optical routing, color separation, and laser systems.
We support low-polarization, high-uniformity beamsplitter films for photonics applications.
4. ITO / FTO Conductive Coatings
Transparent conductive coatings for:
– MEMS sensors
– touch devices
– smart glass
– microelectronics
We supply high-clarity, low-resistance ITO on quartz, borosilicate, and thin glass.
5. High Reflective (HR) Coatings
For mirrors, laser optics, and instruments requiring controlled reflectivity across VIS or NIR bands.
