High quality thin film production technology
In order to respond to requests of special optics technology, the designed thin film must be layered correctly on the base material.
For that, we utilize materials according to the respective purposes, select filming substances and prepare several production methods.
We can handle not only the usual executable wavelength area, but also a large area from ultraviolet rays to infrared rays.
Optical technology is one of the most attention technologies today, embodying the ideals of the future.
We believe that Tokai's technology can assist your development business.
A complete production line
Based on the continuous improvement of quality, technology and productivity , we have introduced the newest equipment and technology, with our production line.
We provide total support, from prototyping and product development to mass production, according to customer requests and circumstances
Electron beam (EB), which heats and evaporates multiple evaporation sources individually with an electron beam, ion-assisted (IAD), which enables film formation with high density and high adhesion without wavelength shift, and low-temperature film formation with no wavelength shift. We carry out cutting-edge thin film processing by making full use of equipment such as sputtering that can obtain high-quality optical thin films.
In addition to the coating room, we have constructed a clean room under the environment of the production process to prepare the environment.
With the aim of improving quality, technology and productivity, we have introduced the latest equipment and technology to form a production line.
We provide total support, from prototyping and product development to mass production, according to customer requests and circumstances
A quality control system
Thorough our quality control is what we put a lot of effort into in order to stably supply products that meet the needs of our customers and earn their trust.
In order to ensure the quality and functions after film formation, we have accumulated know-how from inspection to various measurements, and we conduct quality control according to the standards set based on ISO9001.
We have received orders from customers in a wide range of genres and have delivered high value-added and competitive products in any era.
and we have been highly praised by many industries for our quality standards and our multiple and various processed products, as well as many delivery results stand as actual proofs.
Tokai's strength is its ability to provide "high quality" products.
