About wave plates

A wave plate is an optical element that can convert the oscillation direction of light to any desired direction. For example, a wave plate that provides a phase difference of 1/2 with respect to the incident light ray is called a 1/2 wave plate. By using a 1/2 wave plate, the oscillation direction of linearly polarized light incident at 45° to the optical axis can be rotated by 90°. Additionally, a wave plate that provides a phase difference of 1/4 with respect to the incident light ray is called a 1/4 wave plate. It can function as a circular polarizing plate when used in combination with a polarizing plate. There are also various other types of wave plate elements for different applications, such as 1/8 wave plates that can convert linear polarization into elliptical polarization. They are used in a range of settings, including control rooms for systems and devices that employ lasers as light sources, as well as optical imaging equipment and optical communication devices.

AGC’ wave plates

AGC's wave plates are the world's first distinctive optical elements that integrate glass substrate, organic thin film, and optical design technologies to greatly enhance the performance and design flexibility of optical devices. This is distinctive technology that piles up the organic thin film functional material on the glass substrate in layers, thus accumulating various functions in which conventionally individual parts have assumed into one element compactly. Additionally, it can be used in a variety of applications by combining the technologies which synthesize laser light with a different wavelength and bends only the selected light. AGC has distinctive custom design technology and high-precision microfabrication technology to achieve optical control to meet customers' requirements.
