Added a 650nm short pass filter to the artisan coating.

The short pass filter selectively transmits light below a certain wavelength while blocking light of longer wavelengths. This allows for effective handling of light in specific wavelength bands.
(Do you have any of the following concerns?)
■ Is it possible to customize due to high wavelength dependence?
■ If light is incident at an angle, performance decreases; can it be controlled?
■ When blocking specific wavelengths, there may be a decrease in transmittance.
■ Can it cause chromatic aberration?
■ Is it difficult to control multiple wavelengths simultaneously?
Please consider the optical thin films from Adachi Shin Sangyo Co., Ltd., which can be customized to meet your needs.

Design and customization are possible for the requested wavelength range.
We can design and coat (film) according to the wavelength area requested by the customer. Control in both the transmission region and the blocking region, as well as the angle of incidence, are also important factors.
We will design according to the characteristics of the substrate and the customer's requirements, so please provide the type of substrate and wavelength range when making inquiries.
However, the substrates that can be coated are limited, so prior confirmation is necessary.
