# Diffractive Optical Elements (DOE)

### Diffractive Optical Elements (DOE) ​

By using a DOE lens, it is possible to control the direction and angle of spread of the incident light, as well as the distance and shape of the focal point.

We design, simulate, prototype and mass-produce DOE lenses for a wide range of applications.

### Special Structured Light for 3D sensor

We offer a full range of services from design to mass production of DOEs for 3D sensors according to your requirements.

### Example of Light Control with DOEs

Light condenser, beam angle, directional control example

#### Model 1: Design of DOE for Collimation ​

With our originally developed Large Area Nanoimprint Technology, the cost for processing can be drastically reduced, so it is spreading to various applications now.
“For large area glass: single-shot fabrication on G5 (1,100mmX1,300mm)” and “For wafer fabrication: high throughput at most φ8 inches” can be done.

It is possible to use DOE to convert an expanding angle light source to collimated light.

#### Model 2: Example of the DOE design for light condensers

It is possible to fabricate light condensers using DOEs.
Also, compared to conventional lenses, they can be made significantly thinner.

#### Model 3: Design example of DOE for chromatic aberration correction ​

It is possible to compensate for chromatic aberration using two-layer structures of DOEs
