The new Ricoh FL-CC1218-5MX and FL-CC1618-5MX lenses are designed for use with 2/3" format, 3.45μm pixel pitch cameras. They have a small diameter of 33 mm, but have optical distortion of less than 0.1%. They deliver sharp, high contrast images and even light distribution together with 147 line pair/mm resolution over the entire image measurement field. This satisfies S-Rank (Best Performance Class) criteria as part of the JIIA (Japan Industrial Imaging Association) high-performance class/evaluation standards for high definition camera lenses.
The lens design features a floating focusing mechanism, where some of the lens elements move during focusing while others remain fixed. This configuration minimizes changes in aberrations due to object distance, giving maximum performance at any magnification. The lenses can therefore capture low-distortion, high-resolution images throughout the working distance range from infinity right down to their minimum object distance.
By combining excellent performance with a mechanical design that includes locking screws to prevent movement of focus and iris, the lenses can be used in a host of challenging industrial applications including:
These lenses can also be used as visual sensors in any machine’s vision system making them perfect for robot vision applications. The low aberrations at any working distance also make the lenses well suited for use in intelligent traffic technology.
