This series of high resolution lenses are developed to be installed in machine vision systems with cameras with sensors up to 12 megapixel for 1.1 inch format and 9 megapixel for 1 inch.
Key Features
   
   
Floating focusing mechanism
 • The use of a floating mechanism in their focussing systems allows them to capture low-distortion, high resolution images at all distances, from infinity right down to their minimum object distance, demonstrating maximum performance at any magnification.
 
Bright and clear to the periphery

 

• Despite the small diameter of 42 mm, the vignetting has been reduced to the minimum. Combined with the 12 megapixel resolution, bright, high contrast images are achieved all the way to the edges.

 
 
Extremely low distortion
 • The optical distortion of this series is generally ~2%, (wide angle lens FL-BC1220-9M) or less, partially even < 0.1 %. The resulting extremely low-distortion images are excellent for use in the image measurement field.
 
Compact design

 

• To suit 44 mm housings used for most 12 megapixel cameras, these lenses have a 42 mm compact design ideal for installation with high performance equipment.

 
 
Other features:
