Peripherals Sights on the periphery


A round up of the latest releases of peripheral devices for vision systems, including lenses and cabling


Alrad Imaging is now providing lenses from VS Technology (VST), a Japanese company established in 1997. VST specialises in design, development and manufacture of products for machine vision markets. Tis includes a wide range of high performance optical components for use in demanding applications such as quality testing, alignment, measurement and OCR. As well as popular types of lenses,


such those for CCTV and factory automation, VST offers more complex designs optimised for special applications involving macro, low distortion, vibration resistance, very high resolution and different telecentric requirements. Lenses for work in UV and NIR regions are also available. www.alrad.co.uk


Alysium-Tech has released a USB 3.0 cable assembly that can achieve 10m application length. Te cabling is available from Framos. USB 3.0 offers impressive


transmission speeds of 5GB/s, thereby exceeding common machine vision interfaces such as 1394B, Gigabit Ethernet and USB 2.0, with accessibility exceeding that of Camera Link approaches. Te only major restriction is cable length, which is limited to around 2m for consumer grade materials. Drawing on capabilities in


parallel twinax constructions, which are typically applied in high- performance cabling applications


like multiplexing switching systems in telecoms, Alysium-Tech created a cable design which significantly exceeds the commonly available levels. Plugs are processed with machine vision requirements in mind, exceeding EMC requirements such as FCC Class B, and offering screw locking to ensure durable connections with 80°C temperature rating. www.framos.eu


Edmund Optics (EO) has introduced Techspec SWIR fixed focal length imaging lenses. Tese commercially available lenses are designed, coated and tested for the 0.9-1.7μm shortwave infrared wavelength range. EO manufactures its SWIR lenses from optical elements that are specifically designed for SWIR wavelengths. Te lenses are available in a 50mm


focal length in addition to a 25mm focal length option. Te 50mm is offered with C-Mount, F-Mount and M42 x 1.0mm options in order to work on a wide selection of SWIR


Te new cable is fitted with


Stemmer Imaging’s in- house cable production facility has introduced a new, lower cost CAT5e-rated drag chain- compatible cable. Designed to overcome the limited availability of CAT6 cables suitable for robotics and drag chain applications, the cable portfolio offers improved electrical transfer properties with high data integrity and is ideally suited to image transfer applications.


moulded connectors to provide robust connection to drag chain- compatible cable using RJ45 plugs. Horizontal or vertical fasteners are available to suit all types of camera connection. As with all drag chain-


compatible cables from Stemmer Imaging, the outer material of the new cable consists of high quality polyurethane (PUR) in order to withstand the high torsional and flexural strain experienced in these applications. Naturally the cable material conforms to the latest standards and is therefore free of silicone, adhesive-repelling substances, halogens and CFCs. www.stemmer-imaging.co.uk


lenses serve as an ideal solution for SWIR imaging applications, including inspection, sorting and quality control. www.edmundoptics.com


Intercon 1 has introduced the MIL-DTL-38999 circular connector option for Intercon 1 Camera Link cable assemblies. Te device has a rugged bulkhead


cameras. Tey feature a broadband anti-reflection (BBAR) coating from 800nm to 1.8μm to optimise transmission. Te lenses have low f/#s for high throughput and excellent performance. SWIR FFL lenses are commercial

connection for severe environment applications, providing high quality and dependability in the most demanding of applications. It allows for isolation of the camera from the computer and provides protection from harmful elements such as vibration, moisture, salt spray, sand or extreme temperatures. www.intercon-1.com


Resolve Optics has released its Model 228 lens, providing high performance in both the UV and visible wavebands. Te lens enables forensic scientists and crime scene investigators to identify and focus on a target in the visible and then quickly slide the UV filter across to take images in the UV without having to refocus. By using a novel telescopic


focusing mount, the Model 228 lens gives a large movement in an extremely compact form. Te lens can image objects from infinity to 1:1.25 magnification without using add-on adapters. Te lens offers high-resolution


macro images for fingerprinting and human skin damage applications. O www.resolveoptics.com
