BAD KREUZNACH, Germany, Sept. 11, 2007 -- Schneider-Kreuznach said its new MacroVaron 85-mm, f/4.5 lens for machine-vision systems features the company's new continuous aberration suppression (CAS) technology.

The MacroVaron lens enables system integrators and equipment manufacturers to significantly improve the reliability and flexibility of quality assurance processes in production inspection systems, Schneider-Kreuznach said. The company's unique CAS technology within the lens enables the use of ultrahigh resolution down to 2.5 µm over an extremely large magnification range from 0.5X to 2X, with uniform performance over the entire range.

MacroVaron.jpgA 62-mm image circle, low distortion and excellent chromatic correction make the MacroVaron lens ideal for high-resolution line-scan applications up to 12 k (and down to 5 µm-pixel sizes), such as those used in flat-panel display (FPD) and printed circuit board (PCB) inspection systems, the company said.

The relative illumination of the lens is virtually constant over the entire image height, enabling the use of the full size of the sensor. This uniformity of light eliminates the need for electronic compensation, minimizing the camera signal's noise. The 85-mm focal length of the lens reduces the required working distance, which decreases the space needed for the camera-lens assembly.

“The powerful diffraction-limiting capabilities of the MacroVaron lens represents a major breakthrough for system integrators and equipment manufacturers seeking to improve the performance and efficiency of their machine-vision systems,” said Dirk Muschert, director of marketing. “Much like the recent groundbreaking introduction of our 12-k Makro-Symmar line-scan lenses, the MacroVaron lens with CAS technology represents Schneider-Kreuznach’s commitment to expanding the boundaries of modern technology trends in the industry.”

Like all of its industrial macrolenses, the MacroVaron features Schneider-Kreuznach’s unique iris-locking mechanism and rugged design, to ensure extremely reliable and precise measurements in even the harshest high-vibration manufacturing environments, the company said.

GLOSSARY
aberration
A departure from ideal paraxial imaging behavior. The distortion of an optical field wavefront as it is propagated through the elements of an optical system. The field distortion is due to the interaction of the wavefront with ideal components and therefore a result of optical component behavior.
chromatic
Having the property of color.
illumination
The general term for the application of light to a subject. It should not be used in place of the specific quantity illuminance.
image
In optics, an image is the reconstruction of light rays from a source or object when light from that source or object is passed through a system of optics and onto an image forming plane. Light rays passing through an optical system tend to either converge (real image) or diverge (virtual image) to a plane (also called the image plane) in which a visual reproduction of the object is formed. This reconstructed pictorial representation of the object is called an image.
lens
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
light
Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
resolution
1. In optics, the ability of a lens system to reproduce the points, lines and surfaces in an object as separate entities in the image. 2. The minimum adjustment increment effectively achievable by a positioning mechanism. 3. In image processing, the accuracy with which brightness, spatial parameters and frame rate are divided into discrete levels.
