1995A–IMAGE–04/02
Electro-optical
Performances
Without Infrared Cut-
off Filter
The TH7815ACC special semiconductor process enables to exploit the silicon’s high
near infrared sensitivity while maintaining good imaging performances in terms of
response uniformity and resolution. Typical changes in performance with and without
OR filtering are summarized below:
Pixel Saturation
Adjustment
TH7815ACC antiblooming structure can be used to adjust the maximum saturation volt-
age, by adjusting the
