New Generation EXview HAD CCD Ultrahigh-Sensitivity Near Infrared Structure

Higher sensitivity is a never-ending theme, especially in image sen-

Near infrared sensitivity: +4.5 dB higher  
than earlier Sony products at the 950  
nm wavelength  
sors for surveillance cameras.  
Until now, to respond to these needs, Sony has provided a lineup of  
EXview HAD CCD image sensors that displayed the industry's top  
level of sensor sensitivity.

: EXview HAD CCD is a trademark of Sony Corporation.  
Sony has refined this EXview HAD CCD technology even further and  
has succeeded in developing technologies that improve sensitivity,  
especially sensitivity in the near infrared, significantly.  
Now, Sony has developed the ICX658/659 image sensors that adopt  
these leading edge Sony technologies as CCD image sensors for sur-  
veillance cameras, especially day/night cameras.  
propriate for imaging with LED and other  
near infrared light sources. See table 2 for  
a comparison of imaging characteristics.  
ICX658/659 spectral sensitivity character-  
istics and figure 2 shows the spectral char-  
acteristics of the increases in sensitivity  
provided by the ICX658/659 with the  
ICX258/259.  
The ICX658AKA/659AKA and  
ICX658ALA/659ALA (ICX658/659) are  
diagonal 6 mm (Type 1/3) 380K/440K-  
effective pixel color and B/W CCD  
image sensors developed for use in sur-  
veillance cameras.  
The ICX658/659 image sensors were  
developed with the particular goal of  
increasing the near infrared sensitivity. It  
is in day/night cameras that the ICX658/  
659 can exhibit the true value of their high  
near infrared sensitivity.  
High Near Infrared Sensitivity  
In the ICX658/659, Sony improved on the  
conventional photodiode and developed  
a structure with an even higher photoelec-  
tric conversion efficiency. This structure  
succeeds in capturing even more of the  
near infrared region light that escapes to  
the substrate side in normal CCD image  
sensors.  
The result is that the existing EXview  
HAD CCD technology, which had the  
industry's top level of high sensitivity for  
surveillance CCDs has been evolved even  
further, and these devices feature in-  
creased sensitivity not only to visible light,  
but in the near infrared region as well.  
Compared to Sony’s conventional ICX258/  
259 products, the ICX658/659 achieve  
increased sensitivities of +10% in the vis-  
ible range, and +4.5 dB in the near infra-  
red (wavelength: 950 nm). (See photo-  
graph 1.)  
Excellent Compatibility with  
Conventional Sony Products  
The ICX658/659 were designed to mini-  
mize as much as possible any difficulties  
in their use as replacements for the  
ICX258/259. In particular, the image size,  
pixel counts, recommended drive timings,  
pin configuration, and package are all  
identical. (See table 1.)  
We strongly recommend that customers  
currently using the ICX258/259 look into  
the performance of the new generation  
EXview HAD CCD ICX658/659 image  
sensors.  
Furthermore, these image sensors are ap-

The performance of the CCD im-  
age sensors used in monitoring  
applications is directly linked to  
the performance of these crime-  
prevention cameras. Thus I found  
this a rewarding development ef-  
fort, since it may lead to a social  
contribution in improved crime  
prevention. I was just one of the  
many people involved in this  
project. I strongly urge that you  
take advantage of the superb per-  
formance of the ICX658/659, which  
incorporate the enthusiasm and  
spirit of many of us here at Sony.  
We hope the ICX658/659, which can  
make effective use of the near infrared  
light invisible to the human eye, will make  
new applications possible in the image  
sensing field.
