CAM/CCD-2KLV.TDI and CAM/CCD-4KLV.TDI High Performance TDI Line Scan Camera

1.1 Camera Highlights

Description

The Osprey TDI camera series is an ultra-sensitive camera design for use in line scan applications that demand high performance under low light conditions. This series of cameras is based upon Fairchild’s CCD525 array, which is used in the very successful U.S. Postal Service Wide Field of View (WFOV) Camera. The 2K camera versions have 2048 pixels in the cross-scan direction, with selectable TDI stages up to 96 rows. The 4K varieties have 4096 pixels in the cross-scan direction, also with selectable TDI stages up to 96 rows. The 2K Osprey supports scan rates up to 46K lines per second while the 4K yields up to 23K lines per second. Both the 2K and 4K styles have LVDS outputs. The LVDS output supports 4-port, 8-bit synchronous data. This camera also includes sophisticated features such as anti-blooming, programmable gain and offset. It is packaged in a very compact and rugged housing that contains a standard M58 x 0.75 base lens thread. Optional (Nikon-F) lens adapter is available.
