Why TOYOTEC and RDL?
We received an inquiry about RDL through an introduction of VR/AR system development company that was aware of the customer’s challenges and TOYOTEC’s technology. In addition, TOYOTEC is capable not only of designing special lenses such as RDLs, but also of customizing design specifications to meet the customer’s needs.

Prospects for the Future Based on the Effects and Changes Resulting from the Introduction of the System
Although we are still in the introduction study stage, the actual test simulation has reduced the burden of calibration for distortion correction. We have received feedback that this technology will become even more necessary with the introduction of high-resolution cameras in the future.

The customer had been using a camera that caused distortion, and the CPU load was being used to correct the distortion.
As a result, they were unable to achieve the obstacle detection they originally wanted to implement.
We proposed our RDL lens, a “wide-angle, distortion-free lens,” which eliminates the need for distortion processing because the lens itself performs the distortion correction.
This eliminates the need for distortion processing and helps reduce the load on the CPU.

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 customer had been using general market-sold cameras before they approached us, but they were facing the problem of “narrow field of view” and needed to use multiple cameras for each crane. In addition, they were concerned about peripheral distortion when combining the images taken by each camera.
They were interested in our RDL, which can take wide-angle images with less distortion, because it can reduce the number of cameras and reduce the burden on the system during image processing.

This customer was looking for an optical manufacturer that could manufacture the product they were considering, and came to know about us at an exhibition.
At that time, they were also interested in the fact that we have a lot of experience in manufacturing prisms.

We repeatedly conducted 2D simulations using an ideal lens to evaluate focal length, image formation, resolution, and MTF performance.
We also proposed the optimal optical arrangement for the actual product by using the “Shine Proof Principle,” which states that when the object surface and the main surface of the imaging lens intersect in a straight line, the object surface that is in focus also intersects in the same straight line.
The customer was very pleased when we proposed the optimal optical arrangement for the actual product.

In this way, TOYOTEC proposes the optimum optical design according to the customer’s specifications and application. We offer optical design proposals that include not only optical lenses, but also mechanical units such as sensors and modules.
Please feel free to contact us if you have any questions about optical product research and development.

This customer was looking for a lens that can take wide-angle photos in a limited space such as between lanes in a green house. They were also looking for a solution to the problem that stick-shaped plants such as cucumbers
They were also looking for a solution to the problem that stick-shaped plants like cucumbers are easily affected by distortion during image recognition.
We proposed our RDL lens, a “wide-angle, ultra-low-distortion lens,” to the customer as a lens that could solve both problems.

The customer used to use wide-angle cameras on their forklifts, but they had to correct distortions as needed. However, the more the distortion correction, the further it became from real-time, so they were looking for a product that could acquire undistorted images in real-time.

Cameras for moving objects such as forklifts need to detect obstacles and people in warehouses, and acquiring information from as wide a field of view as possible will improve their performance. However, the wider the angle, more distortion correction needed to make a higher accuracy of analysis. This inevitably results in a slower frame rate (fps), which means that information processing takes longer and lacks real-time capability.

On the other hand, the ultra-low distortion lens unit developed by TOYOTEC is capable of sensing up to a horizontal angle of view of 120 degrees, and our unique optical design technology reduces distortion to less than 2%. This eliminates the need for distortion correction by image processing and enables high fps shooting. Elimination of distortion correction also eliminates the loss of pixels due to image processing, resulting in the acquisition of high-quality images in real-time.

This ultra-low distortion lens unit have been used not only by these customers, but also in a wide range of fields such as agriculture, production, and surveillance cameras, and has been highly appraised by our customers.

The customer who was planning to develop this product had never customized optical components themselves, and have ordered this sensor by OEM. This time, however, their manufacturer was unable to meet the requirements of the catalog products, so they turned to us to find an optical manufacturer that could consult with them on the entire project, starting from zero design.

This coin image recognition sensor required a short focal length of 1.8 mm, and the imaging range and object distance is to set so that the entire coin will be captured. Therefore, we succeeded in developing this lens unit by creatively designing a combination of glass lenses and metal parts.
