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 a CameraLink

TM

 output.  The 

CameraLink

TM

 output supports 4-port, 8-bit synchronous data.  These cameras also 

include sophisticated features such as anti-blooming, programmable gain and 
offset.  They are 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.
