5 Mega-Pixel Lens (Manual Iris Lens, compatible with 5 mega-pixel cameras)

FA lenses for use with 5 mega-pixel resolution and image processing
There are five types, beginning with an 8 mm focal length close-up lens

These manual iris lenses support 5 mega-pixels (2/3" format). They are perfect for inspection, pattern matching, and alignment uses in which images with high definition from edge to edge definition are needed for large subjects such as wafers, chip mounters, board mounting, etc.

■High resolution and high contrast
Supports 2/3" format, 5 mega-pixel CCD camera with 3.45μm pixel pitch. Achieves 140 lp/mm high resolution from center to periphery. Produces sharp, high-clarity images with high-contrast and low resolution loss all the way to the edge.

■Φ43 mm compact design
Consistent with the 44 mm-square cases used by many 5 mega-pixel cameras, we have achieved a size reduction to Φ43 mm for the outer diameter. These lenses are an excellent choice for installation on high-performance devices.

■Extremely small level of optical distortion
For both the FL-CC2514-5M and the FL-CC1614-5M, optical distortion on the diagonals is less than 1%. TV distortion is held to less than 0.2%. The resulting extremely low-distortion images are also excellent for use in the image measurement field.

■Bright to the periphery
Despite the Φ43 mm diameter, the optics accommodate 5 mega-pixels with F1.4 brightness. With peripheral-light-intensity falloff held to an absolute minimum, it is possible to obtain bright and high-resolution images. Although they are wide-angle lenses, with the iris open we were able to raise the peripheral light level to 70% (diagonals) and thereby achieve images that are bright and clear all the way to the periphery.
