Machine Vision

Providing new value for increasingly sophisticated industrial lenses such as high resolution, expanded wavelengths, IoT, and remote control

Market trends and issues

In the machine vision industry, with the evolution of image sensors, there are rapidly growing needs for increased resolutions, wavelength ranges and high-level functions. As AI judgment becomes mainstream, with growing social needs for unmanned factories and IoT, Computar will always respond with products that incorporate new value such as remote-controlled lenses, digitally-controlled lenses, and other increases in performance such as the development of inspection lenses that use infrared and ultraviolet as well as visible light in order to expand the applicable wavelengths


Computar's machine vision lenses lineup, featuring a range of functions such as high resolution and electrification, extends to every part of the manufacturing line, covering printed circuit board inspection, package encapsulation inspection, automatic operation of processing equipment, quality control, material sorting, and so on.

At Computar, our unique expertise in developing lenses for both security and machine vision are used to pioneer new needs along with our existing two-way practical knowledge and multifaceted imagination, as well as fusing cutting-edge technology, in fields where new technical evolution is expected, such as industrial robots and mobility systems.

  • Support for a range of subjects through Lens Connect® technology, which transplants the latest security control technology into machine vision lenses.
  • The development of drone lenses that fuse the performance of high-resolution lenses, our skill in making large sensor formats, and our expertise in physical miniaturization, as well as the application of machine vision technology in ITS.
  • The development of large-aperture lenses for fluorometric imaging in faint light that use existing security low-light lenses as new technology for medical devices.

At Computar, we are developing lenses that never go out of focus from visible light to near infrared (NIR), ultra-large aperture lenses that swept the industry, and other lenses specialized for medical or specialist use that go beyond the borders of the monitoring or machine vision markets. Drawing on our expertise in the design and manufacture of these specialist optics, we pioneer new needs and provide products with value.


Future Prospects

We believe that it is more important than anything to provide machine vision lenses not only measured by their high performance as single, independent devices, but also to provide "machine eyes" more suitable as a part of solutions for inspections based on the perspective of machine recognition. To meet the ever-growing needs for optical lenses in the various fields of society and industry, we go beyond the boundaries of machine vision or security, aiming to create the sort of products that only Computar can.


Electronic parts inspections From micro-machined parts to FA process inspections,
our high-precision, compact products cover all areas

There is a wide variety of electronic parts that get inspected, from semiconductors to miniature chips, electronic parts, connectors, and harnesses. Additionally, a wide range of inspections are required in production processes, from visual inspections of the target, dirt inspections, dimension inspections, alignment, and OCR to process monitoring for the equipment. In particular, as semiconductors and parts for electrical devices such as smartphones get smaller and smaller, there is a growing demand for compact lens design, close-up capability, high definition, high pixel counts, high sensitivity, and low distortion. At Computar, we have accumulated a solid track record, such as the use of 20 megapixel lenses for visual inspections of micro-machined parts for smartphones, telecentric lenses for visual inspections of automobile connectors, along with macro zoom lenses on robot arm cameras for die bonding process monitoring. We will continue responding to the diversifying market with Computar's unique products such as our large aperture, compact lens series and the ViSWIR lens series that supports a wide range of wavelengths, from visible light to short wavelength infrared.


Automobiles Automation and low cost:
a product field expanded through the pioneering of new needs

Visual inspection equipment is increasingly used in the production and assembly processes of automobile parts such as connecting rods and transmissions. In machine vision in particular, more and more competitors are arising with the expansion of new needs, and it is increasingly common to see them join up with automobile manufacturers or Tier 1 parts manufacturers. Additionally, with the shift from visual to automatic inspection due to inspectors retiring and labor shortages, the expansion of the range of parts that can be inspected, and the lower equipment costs, needs for high-precision inspection equipment will continue to grow significantly. With the use of robot arms as automation equipment becomes increasingly common, lenses now have to withstand vibrations as well. At Computar, the use of monofocal lenses used to be mainstream, but now we carry a wide range of lenses to cater to all sorts of inspection targets. We develop lenses to suit applications as we constantly unearth new needs. In future, we aim to work with the wide-ranging automobile industry through things like 3D scanners and automated driving.


Foods, Pharmaceuticals and Cosmetics Using high-resolution, high-performance lenses for the diverse needs of image recognition cameras

A wide range of inspections are carried out in the three rapidly-developing product fields of medical products, foodstuffs, and cosmetics, including visual inspections of packaging/bottling, reading and inspection (OCR) of the letters/numbers printed on them, and reading barcodes. All this requires highly precise image recognition, and in some cases, 3D inspections or specialized image recognition are also used. This means that lenses need to perform to high levels, with high resolutions, low distortion, reduced chromatic aberration, short working distances, and miniaturization. Computar's 20-megapixel lens series and our 4/3rds inch series provide solutions that meet most of these demands. It is also likely that objects that were previously hard to inspect will now be included as targets as AI-based image processing advances, and so we expect the scope of image recognition to broaden still further. We developed the ViSWIR series for hyperspectral and multispectral cameras used for these sorts of image processing. Computar will offer a unique lineup that allows for the needs of our customers in the future.
