Product focus Optical options


A product roundup of the latest lenses for machine vision, including C-mount, telecentric, and infrared models


Basler is now offering its own C-mount lenses, designed in cooperation with Fujinon. Te high- resolution lenses work on Basler Ace and Dart cameras, or any camera with a sensor smaller than ½-inch, and are available in six focal lengths. Te lenses are suitable for sensors with very small pixels, such as the 5 megapixel sensor from Aptina with a pixel size of 2.2µm. Tis represents a key step in delivering top image quality for popular machine vision applications. Te outstanding price/ performance ratio is another factor, with models starting at €99. www.baslerweb.com


Multipix Imaging has launched new lenses from Opto Engineering, including the TC4K telecentric lens series designed for measurement applications using 4k line scan cameras. Te ‘flat’ compact shape makes the lens easy to integrate within tight size constraints. TC4K series feature standard F or M42 mounts to fit common line scan camera interfaces. Te lens-camera interface provides


both fine detector phase adjustment and a precise focusing mechanism. Detector-phase adjustment means the linear FOV can be positioned precisely at 90° to the object movement direction. Also now available is the TCLWD


series, a range of telecentric lenses specifically designed for electronic and semiconductor automated optical inspection (AOI) and tool pre-setting machines. All lenses feature a long working distance of 135mm while ensuring excellent optical resolution, high telecentricity and low distortion. www.multipix.com


Edmund Optics now offers its Techspec high resolution telecentric lenses for one-inch sensors. Tese lenses are designed for semiconductor and electronics inspection, and measurement and gauging applications. Tey provide a compact, cost-effective solution for replacing standard fixed focal length lenses. Te lenses feature high


light throughput f/6 designs, while exhibiting less than 0.1° telecentricity and less than 0.1 per cent distortion. A double sided telecentric design gives sharp images with few errors


Navitar has released its line of MagniStar high resolution bi- telecentric lenses, which are ideal for industrial and electronic parts inspection where greater depth of field is necessary. Te lenses offer high telecentricity, excellent MTF performance, no parallax error, and less than 0.1 per cent image distortion. Te MagniStar line includes six C-mount lenses with built-in adjustable iris for 2/3-inch or smaller sensors, as well as a large format f-mount lens for 43.3mm. Magnifications range from 0.05X to 2X. Also available from Special Optics,


for accurate measurements. Te product supports up to 16mm maximum diagonal sensors and are designed to accommodate up to 16-megapixel resolution sensors. Te lenses are ideal for use in


high-vibration environments, featuring an optional recessed screw to permanently secure the iris in place. www.edmundoptics.com


a Navitar company, are custom microscope objective lenses with working distances from 0.3mm to 30mm. Te lenses are tailored to function


at wavelengths from visible light to the near infrared, can be modified for aqueous, oil, and vacuum research environments, and can be designed with stainless or Ultem housing. www.navitar.com


Te Model 307 from Resolve Optics is a high performance, 40mm focal length,


infrared lens designed specifically for thermal imaging applications in the 8-14µm waveband. Manufactured from germanium,


Model 307 lenses are supplied with antireflective coatings that ensure high performance (f2) throughout the IR waveband. Operating from zero to 40°C without refocusing, the fixed focus lens is compact, robust, and available at an affordable price. www.resolveoptics.com


Schneider- Kreuznach has launched its HT industry filters at Vision 2014. Tis


series of filters has been designed for use in industrial vision applications. Tanks to a new coating process (magnetron sputtering), higher and consistently even transmission can be achieved with steep slopes and better blocking outside the transmission range. Te anti-reflective coating provides reduced reflectivity in the visual and near infrared spectrum and is also harder and therefore more robust. Schneider-Kreuznach is also now offering customisations for specific applications. Tis applies to the coating that can be designed for specific transmission and reflection wavelengths, and highly precise geometric pre-cuts are also possible. Free forms can also be produced using a micro- water jet cutter. www.schneiderkreuznach.com
