High quality lenses for machine vision.

Senko ADL : 26 July, 2007  (Application Story)
SenkoADL day/night vision lenses coupled to NEXVS DVRs being used in quality control function at European automotive supplier.
Vari-focal lenses from SENKOADL are being used by one of Europe's largest automotive component manufacturers in south-western Germany on a machine vision application.

The lenses, which have a focal length of 7.5~50mm, are from SenkoADL's "pro" series. They are being used here with 1/3in double progressive scan cameras from videotronic infosystems.

The client, who employs 2,000 staff and supplies parts for the world's best-know car brands, is recording images from the lenses to 16-way NEXVS Digital Video recorders which have also been supplied by videotronic infosystems, a Vicon company based in Neumuenster, Germany.

Of course such functionality is not relevant to the machine vision application described here, but installers working on other projects dealing with both white and infrared light will appreciate that these are day-night lenses which accommodate the IR focus shift.

Across widely differing conditions, the units deliver outstanding image quality using SenkoADL's high-resolution Japanese lens technology and extraordinary low dispersion (ED) glass. Tolerance on the precision equipment manufactured by this client is such that the slightest abnormality in a component must be addressed on the assembly line.

Installers in the UK and Europe should note that SenkoADL has a European headquarters in Berkshire, England. Extensive warehouse facilities and skilled engineers ensure that installers benefit from rapid turnaround and exceptional customer care.

The SenkoADL lens used on this automotive project has an iris range of F1.3-F360 and the iris drive is DC auto. The lens can be used with 1/3in and 1/4in cameras, both colour and black & white. Horizontal field of view is 36.6deg x 5.64deg with a 1/3in camera and 27.4deg x 4.26deg with a 1/4in camera. Dimensions (mm) are 38 x 50.1 x 55.2 and the lens weighs 68gs. This is a CS mount unit.
