Optical Coating

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.

Applications of Optical Coating Services

Our custom optical coating services are applied across multiple industries:

  • Semiconductor packaging & MEMS – Protective and functional coatings for wafers, interposers, and sensors.
  • Photonics & fiber optics – Sputtering optical thin films on substrates for splitters, couplers, and waveguides.
  • Medical devices – Laser windows, endoscopes, and high-transparency optical filters.
  • Scientific instruments & laboratory optics – Spectroscopy, microscopy, and imaging devices.
  • AR/VR displays & sensors – Vacuum deposition glass coatings for high-performance optics in consumer electronics.

These use cases highlight why choosing a custom optical coating manufacturer with both raw material and thin-film expertise is essential.
