Features

STF-4070M, STF-4070C and STF-4070SC

The STF-4070 camera comes in monochrome (STF-4070M) and two color models. The color models are available with either the standard Bayer Color FIlter Pattern (STF-4070C) or the higher sensitivity TRUESENSE Sparse Color Filter Pattern (STF-4070SC). The KAI-04070 Image Sensor is a 4-megapixel CCD in a 4/3" (21.4 mm diagonal) optical format. Based on the TRUESENSE 7.4 micron Interline Transfer CCD Platform, the sensor features broad dynamic range, excellent imaging performance, and a flexible readout architecture. The TRUESENSE Sparse Color Filter Pattern provides a 2x improvement in light sensitivity compared to a standard color Bayer part.

KAI-04070 CCD Key Features:

• Available in Monochrome, Bayer Color Pattern or TRUESENSE Sparse Color Filter Pattern
• Progressive scan readout
• Flexible readout architecture
• High frame rate
• High sensitivity
• Low noise architecture
• Excellent smear performance
• Package pin reserved for device identification

Description of the TRUESENSE Sparse Color Filter Pattern.

The TRUESENSE Color Filter Pattern represents a new paradigm for obtaining full-color images from a single image sensor. By adding panchromatic (or "clear") pixels to the standard red, green, and blue pixels traditionally used for color capture, image sensors can realize a significant increase in light sensitivity – between two and four times compared to standard designs – while retaining overall image quality and color fidelity. Image sensors using this design allow end users to capture better pictures and video under low-light conditions.

In addition to the new color technology, the STF-4070 has been optimized for fast full frame download and maximum cooling in an STF sized package. A high resolution 4 megapixel 16-bit frame will download in about 1/4 second using the dual channel readout mode. Even at this rapid download rate, the read noise remains exceptionally low, about 9e-.

The STF-4070 was developed primarily for the OEM market, particularly for microscopy applications where short exposures and high frame rates made possible by an electronic shutter are more desireable than having a mechanical shutter for automatic dark frames. Because of this, the STF-4070 cooling design is very robust and the camera is capable of a cooling delta greater than -50 degrees C.
