Distortion-free Optics for Line Scan Applications

MORITEX SCHOTT: High-Resolution Lens for Long Image Sensors of Line Scan Cameras

Tokyo (Japan) / Mainz (Germany), march 23, 2010 — MORITEX Corporation has developed a new lens for high-definition line scan cameras. “ML-L00502” offers an exact, high-contrast picture display at a screen diagonal of up to 62mm, today’s maximum applicable CCD sensor length. The illumination drop between the center and the periphery of the field of view is less than 20%. The distortion of the optic is less than 0.1%.

Machine vision systems that are based on line scan cameras are increasingly being used for quality inspection as well as sorting procedures. Their main area of application is in semiconductor manufacturing, for quality assurance during the production of solar modules and Liquid Crystal Displays (LCD) as well as printed circuit boards for computers, for instance.

Advanced machine vision systems are also being put to use in telecommunications and information technology, as well as biosciences and laboratory automation. Thereby a high throughput rate can be achieved when line scan cameras with high-resolution image sensors and excellent optics are used.

The latest generation of CCD sensors in line scan cameras reaches a resolution of 12,000 pixels 5µm in size. In order to capitalize on this, lenses like the “ML-L00502” by MORITEX offers an extremely low distortion. This also makes them attractive for high-resolution Matrix sensors.

From the center of the image to the edges, the “ML-L00502” offers an exact, high contrast picture display even with a screen diagonal of up to 62 mm. The diaphragm is adjustable. At an optical magnification of 0,05x the working distance is 1,590 mm, at 0,2x 420 mm.

The “ML-L00502” allows for a very compact design of the machine vision system. To achieve homogenous illumination of the objects to be inspected, MORITEX and SCHOTT also offer high-performance LED and halogen light sources, including fiber optic light guides upon request.
