AR coatings can reduce surface reflection and improve transmittance of optical components.
When the angle is tilted from perpendicular incidence, the reflection increases. Therefore, at NDK, we developed the "Low incident angle-dependent AR coating" that can suppress almost all reflections up to an incident angle of 30° by optimizing and devising the film design. This makes it possible to suppress color irregularities, ghosting, etc.

IR-cut coatings can block out light in the infrared region and allow visible light to pass through.
The spectral characteristics change as the angle is tilted from perpendicular incidence. Therefore, at NDK, we developed the "Low incident angle-dependent IR-cut coating" that can suppress almost all reflections up to an incident angle of 30° by optimizing and devising the film design. This makes it possible to suppress color irregularities, ghosting, etc.

Indium tin oxide, which is a mixture of indium oxide and tin oxide, is used as a material to form transparent conductive films.

Can be combined with UVIR-cut coatings and AR coatings

Performance example: Sheet resistance 1.15E+05 ΩRS (actual measurement example)

The final layer of the vapor deposition is coated with a fluorine film.
This treatment improves the surface slipperiness and makes it difficult for foreign matter and dirt to adhere to the surface, and also helps prevent the surface from being scratched.

We can provide optical thin films with low stress based on our unique manufacturing methods and design technologies.
The following is an example of the AR coating, but by combining it with the low reflective design, it is possible to deposit AR coatings with low incidence angle dependence, low reflection, and low stress on large sheets and substrates with dimension and thickness of 45 × 35 × 0.2 mm.
