expects the portable form factor to help broaden the scope of applications for GFX camera systems, equipped with a large format sensor. Kowa lenses have been used
for applications in a wide range of industries such as automotive, logistics, pharmaceutical and food. They perform tasks such as defect detection, surface inspection or shape and dimensional inspection. TracePro from Lambda
Research is used to analyse non-imaging aspects of imaging systems, such as stray light, polarisation effects, thermal loading, bulk scatter, and fluorescence. In addition, its solar emulator and optimisation features ensure solar collectors perform at peak efficiency. Optotune’s focus-tunable
liquid lenses are designed to provide a versatile, compact and cost-effective solution to the challenge of keeping products in focus under the camera or quickly scanning various objects at different distances. Thanks to the absence of translational mechanics, these lenses can focus within a few milliseconds, ensuring robustness and reliability with a lifetime of billions of cycles for use in applications such as quality control, packet sorting, box filling, palletising, barcode reading, robot vision and 3D image stacking. Resolve Optics offers compact
fixed and zoom lenses for vision applications including parts recognition, precise component

placement, automated alignment and placement, and automated inspection of manufactured components. The company recently reported how its custom designed high-contrast shortwave infrared lenses have been used for agricultural sorting applications by optimising both the resolution and imaging contrast achievable with the product. A recent addition from Schneider-Kreuznach to its range of Zirconia lenses is the Zirconia 3.3/90. Designed for line sensors, it has a common magnification 0.1x. The main fields of application are flat panel display and PCB inspection. It has a uniform imaging performance over the whole field of view and, like other products in the Zirconia series, it comes with a V48 mount. Sill Optics provides a range
of telecentric lenses for machine vision applications. The company offers products that include lenses with coaxial light coupling to entocentric macro and wide- angle lenses, and telecentric illumination. Recent additions include the S5VPJ0303 and S5VPJ0305 telephoto lenses, including a tunable liquid lens. They offer high-speed adjustment of focal length to compensate for working distance deviation. Thorlabs offers a wide variety
of C-mount camera lenses for machine vision, including standard fixed lenses, zoom lenses, high-magnification zoom lenses for macro applications, modular zoom lens components, and telecentric lenses. These lenses are compatible with all of the company’s CCD and CMOS cameras. Thermal imaging lenses are available to focus infrared light without introducing spherical aberration, and the company can provide objective, scan, and tube lenses for use in constructing optical systems for machine vision applications.
LAMBDA FEATURED PRODUCT
TracePro combines Monte Carlo ray tracing, analysis, CAD import/export, and optimisation methods with a complete and robust macro language to solve a wide variety of problems in illumination design and optical analysis. TracePro offers luminaire and illumination designers the most accurate and comprehensive design environment available. Luminaire design requires strict adherence to system
performance criteria, including spatial and angular light distributions, uniformity, luminance, and spectral characteristics, along with aesthetic factors, such as lit and unlit appearance. With TracePro, you have the power to accurately simulate the lit appearance of your product, and reduce costly trial-and-error prototyping. Instead, you can virtually prototype with photorealistic rendering. Whether you are designing an instrument panel, light pipes
for switches or indicators, or automotive lighting, TracePro can accurately model the appearance of your design with photorealistic accuracy.

Among its most recent
developments in lenses, Tamron expanded its range of fixed focal length lenses for the machine vision market with the MA23 and MA111-VIR series. The MA23 series targets industrial inspection requirements with its small size and image quality optimised for shorter distances. The MA111-VIR series is optimised for larger
sensor sizes and resolutions, with 1.1-inch sensor format and up to 24-megapixel resolution, addressing a large field of industrial and non-industrial high- resolution applications. This is not an exhaustive list.
