1. Example of usage and application

• Optical thin film for display-related
• Film for index matching for touch panel
• Anti-reflecting film
• Alkaline-resistant film
• ND filter film for digital camera

Function of optical thin film

1)Anti-reflecting film

Under the conditions of, film refractive index= n1, film thickness= d and film optical distance n1・d = λ/4 (1/4 of the wavelength of the light), the reflectance index becomes minimum by interference action of the light. In addition, it is possible to deposit anti-reflective film by laminating a high refraction film and a low refraction film under the most suitable optics design.

2)Transparent conductive film for thin film type of solar cell (Thin film Si type. CIGS type)

3)Dielectric film for Low-E for building (multi-layer film composed of metal and oxide)

• 【Solar cell(CIGS type)】
  

  AZO thin film for high transmittance of sunlight and carring a current.

• 【Low-E multi-layer glass】
  

  Multi-layer film composed of metal and oxide is coated on the glass to intercept infrared rays and ultraviolet rays of the sunlight. The function of ST thin film is to protect aforementioned thin film on the glass from damages of acid-rain and scratch.
