TECH FOCUS: OPTICS Edmund Optics: Featured Product
The lenses cover sensor sizes from ½-inch to 1.1-inch. The 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. Edmund Optics offers a wide range of imaging lenses for a variety of needs, including telecentric lenses, liquid lenses, those with fixed focal length, zoom lenses, and shortwave infrared imaging (SWIR) 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 range covering from 35mm to 70mm. The company 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. 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 SWIR 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
Edmund Optics’ TECHSPEC 120i Infinity Corrected Objectives for machine vision systems are designed to reduce the size, overall system length, and weight of an imaging system while maintaining excellent optical performance. Miniaturisation is currently one of the top trends in optics, especially in the medical devices sector as laboratories shift from bulky setups to more compact and portable units. The TECHSPEC 120i Plan APO Infinity Corrected Objectives are the most compact industrial infinite conjugate microscope objectives on the market and are designed to connect directly to machine vision cameras. Using 120mm tube lenses instead of 200mm or 180mm, these objectives offer the same high-resolution, diffraction-limited performance as other previously available options. They feature C-mount threading to provide easy integration into a wide range of machine vision systems and are designed for use with 1.1” sensor formats. The TECHSPEC 120i Infinity Corrected Objectives are ideal for medical instrumentation, and space-constrained, high- magnification machine vision systems.

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. 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.I
