CV-A1-20

1. General

The CV-A1-20 is a monochrome progressive scan 1/2” CCD camera with 1.4 Megapixel resolution. CV-A1-20 is identical to CV-A1, but the pixel frequency is 20 MHz instead of 28.636 MHz. It is designed for automated inspection, featuring a small housing and a wide range of unique functions. The asynchronous trigger can be set to work in several modes, to allow such functions as pulse width controlled shutter, programmable shutter speed and long time integration. To obtain higher frame rates, the camera has partial scanning and both horizontal and vertical binning.

All modes and functions can be set via an RS-232C interface, greatly reducing the need for mechanical switches or jumpers.

CV-A1-20 Camera Control Tool for Windows 98/NT/2000 contents a camera control program and tools for making your own program.

Camera ID, model name and user ID is present in the camera from revision B. S/N E121231.
