They are used to monitor people and things in various places.

In this case, the lens is mainly used for monitoring inside the station.
The customer wanted to reduce the burden of distortion processing, and was interested in our RDL (Ultra-Low- Distortion Lens Unit), which has low distortion and wide angle, because it optically removes distortion as much as possible and reduces the burden of distortion processing by image processing.

>> RDL: Real Distortion-Less lens unit (Wide Angle, Ultra-Low distortion, and High quality)

TOYOTEC has a proven track record of supporting a wide range of projects from the development stage to mass production.
Since TOYOTEC is capable of handling the entire process from optical and mechanical design to component manufacturing and final product evaluation, we are able to produce original design and development products such as this RDL lens.
RDL lens is sold as a standard product and has its own specifications, but customized products based on the RDL lens are also available to meet customers’ needs.
If you are looking for distortion-free wide-angle lenses, please feel free to contact us.

]]> This is an example of a design proposal of a lens unit used for driver monitoring. The lens unit will be used as a component of a driver monitoring product that is used to prevent drivers from falling asleep at the wheel, which has become a common problem in recent years.

As a result of a defect in the original project, TOYOTEC, which has done business with them in the past, was consulted when looking for another supplier.

Since this project was for in-vehicle use, there was a request to consider cost and temperature drift, so we proposed optical design with multiple patterns such as glass lens only or a combination of resin lens and glass lens. We also adjusted the angle of view and conducted detailed simulations using MTF evaluation, CRA, vignetting ratio, and spot diagrams.

We can of course provide lens unit components, but we can also offer cost reduction and performance improvement proposals if you consult with us from the optical design stage in order to meet your requirements. If you are considering lens unit parts or cost reduction, please consider starting out by contacting TOYOTEC.
