ICX418AKL
Diagonal 8mm (Type 1/2) CCD Image Sensor for NTSC Color Video Cameras
Description
20 pin DIP (Cer-DIP)
The ICX418AKL is an interline CCD solid-state
image sensor suitable for NTSC color video cameras
with a diagonal 8mm (Type 1/2) system. Compared
with the current product ICX038DNA, basic
characteristics such as sensitivity, smear, dynamic
range and S/N are improved drastically.

ICX418AKL Definition of standard imaging conditions 1) Standard imaging condition I: 2 Use a pattern box (luminance 706cd/m , color temperature of 3200K halogen source) as a subject. (Pattern for evaluation is not applicable.) Use a testing standard lens with CM500S (t = 1.0mm) as an IR cut filter and image at F5.6. The luminous intensity to the sensor receiving surface at this point is defined as the standard sensitivity testing luminous intensity. 2) Standard imaging condition II: Image a

ICX418AKL Notes on Handling 1) Static charge prevention CCD image sensors are easily damaged by static discharge. Before handling be sure to take the following protective measures. a) Either handle bare handed or use non-chargeable gloves, clothes or material. Also use conductive shoes. b) When handling directly use an earth band. c) Install a conductive mat on the floor or working table to prevent the generation of static electricity. d) Ionized air is recommended for discharge when handling CC
