These applications require linescan lenses with very high resolution in order to guarantee cost-efficient defect detection in manufacturing and associated quality assurance processes. When using high resolution cameras, the lens is often the limiting factor in the full utilisation of the theoretically possible system performance. The Xenon-Sapphire lenses have been specifically designed for combined operation with 16k linescan cameras such as the Piranha3 16k by Teledyne DALSA. In their optical magnification range they fully exploit all the possibilities of the very latest sensor generation.
The lenses have excellent optical and mechanical properties. The high resolution of the lenses fully utilises the sensor's 3.5?m pixel size. Their coating in the range of 400 to 1000nm ensures optimum luminous efficiency. Precision mechanics and special mounting technology minimise loss of contrast due to manufacturing tolerances. To further improve contrast, the best azimuth can be set using the industrial-grade V70 interface. The aperture setting can be locked in order to ensure high imaging performance even in the presence of strong vibrations.
Xenon-Emerald for high resolution cameras
Many camera manufacturers are using the F-Mount bayonet as the camera/lens interface of their high resolution area and linescan cameras. Schneider-Kreuznach has addressed this topic with the new Xenon-Emerald lenses. These low distortion lenses are compact, robust and lockable. They are available either with 50mm or 100mm aperture and with an image circle diameter of 43.2mm. Depending on type they are designed for close up or long range and optimised for a uniform image quality over the whole sensor area.
The 400nm to 1000nm broadband coating makes them suitable for applications in the visible and the infrared spectrum. Using adapters, the Xenon-Emerald lenses can also be mounted to C-Mount, M42 or M58 connectors. The required extension tubes with lengths of 10, 25 and 50mm will be available soon. These alternative mounts make the new Schneider-Kreuznach lenses even more flexible for a wide range of imaging applications.
