1. General
The LQ-200CL is a 4CCD line scan camera using four 2048 pixel line sensors mounted on a prism, for
the R, G,B and NIR channels. It operates with a 40 MHz pixel clock, resulting in a maximum line rate
of 19,048 lines per second.
The camera outputs digital data in 4 x 8 bits or 4 x 10 bits format via Camera Link. The camera is
configured by software through the serial communication port of the Camera Link interface, or via
RS-232C through a 12-pin Hirose connector.
The camera accepts M52 mount or F-mount lens.
The LQ-200CL is a suitable camera for various applications such as inspection of fruits,
vegetables ,circuits boards or electronic/mechanical parts, as the NIR image can catch scratches or
blemishes on object surfaces which the RGB color image cannot find.

About M52 mount: LQ-200CL employs a new M52 mount as the standard. This mount is
recommended in the lens guide line for machine vision applications which is set by Japan
Industrial Imaging Association in corporation with AIA and EMVA. The title of the guideline is
“JIIA LER 004-2010 Recommended Mechanical Interfaces Applied for Each Image Size
Classification” and issued on March 10th, 2010.
