range covering from 35mm to 70mm. Te company expects the portable form factor to help broaden the scope of applications for GFX camera systems, equipped with a large format sensor. 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. Tanks 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
from ½-inch to 1.1-inch. Te aperture and focus can be fixed mechanically if required, which ensures brightness and image quality remain constant, even if the lens is exposed to vibration. Available from Edmund

imaging lenses. A selection of imaging lens accessories is also available, including filters, and mounts or adapters for additional functionality. Fujifilm offers a wide range
of prime, zoom and telephoto lenses. Its most recent launch is the Fujinon GF35-70mm interchangeable lens for large- format cameras. Designed as a compact and lightweight zoom lens, it weighs around 390g, with a focal length
compact fixed and zoom lenses for vision applications including parts recognition, precise component placement, automated alignment and placement, and automated inspection of manufactured components. Te 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. Schneider-Kreuznach’s
latest addition to the range of Zirconia lenses is the Zirconia 3.3/90. Designed for line sensors, it has a common magnification 0.1x. Te 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. Te company offers products that include lenses with coaxial light coupling to entocentric macro and wide-angle lenses, and telecentric illumination. Its most recent additions are the S5VPJ0303 and S5VPJ0305 telephoto lenses, including a tunable liquid lens. Tey offer high-speed adjustment of focal length to compensate for working distance deviation. Torlabs 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. Tese lenses are compatible with all of the company’s CCD and CMOS cameras. Termal 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. 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. Te MA23 series targets industrial inspection requirements with its small size and image quality optimised for shorter distances. Te 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.
