CCD linear image sensors for spectrophotometry

The back-thinned type CCD linear image sensors are developed for spectrophotometers and feature high UV sensitivity and an internal electronic shutter.

The front-illuminated type offers high sensitivity in the ultraviolet region (200 nm) nearly equal to back-thinned CCD, despite a front-illuminated CCD.

◎ Back-thinned type

These are back-thinned CCD linear image sensors with an internal electronic shutter for spectrometers.

Resistive gate structure

In ordinary CCDs, one pixel contains multiple electrodes and a signal charge is transferred by applying different clock pulses to those electrodes [Figure 1]. In resistive gate structures, a single high- resistance electrode is formed in the active area, and a signal charge is transferred by means of a potential slope that is created by applying different voltages across the electrode [Figure 2]. Compared to a CCD area image sensor which is used as a linear sensor by line binning, a one-dimensional CCD having a resistive gate structure in the active area offers higher speed transfer, allowing readout with low image lag even if the pixel height is large.

◎ Front-illuminated type

The S11151-2048 is a front-illuminated CCD linear image sensor with high sensitivity and high resistance to UV light.

CCD linear image sensors for industry

These are CCD linear image sensors suitable for industry.

◎ TDI-CCD image sensor

TDI-CCD captures clear, bright images even under low-light-level conditions during high-speed imaging. TDI operation mode drastically boosts sensitivity to high levels by integrating signal charges synchronously with the object movement. TDI-CCD uses a backthinned structure to achieve even higher quantum efficiency over a wide spectral range from the UV to the near IR region (200 to 1100 nm).

TDI (Time Delay Integration) mode

In FFT-CCD, signal charges in each line are vertically transferred during charge readout. TDI mode synchronizes this

vertical transfer timing with the movement timing of the object incident on the CCD, so that signal charges are integrated a number of times equal to the number of vertical stages of the CCD pixels.

Spectral response (without window)		Configuration (S10201-04-01)
The back-thinned (back-illuminated) structure ensures higher sensitivity than front-illuminated types in the UV through the near IR region (200 to 1100 nm).		Using multiple amplifiers (multiple output ports) permits parallel image readout at a fast line rate.
