superior image quality

The pco.edge sCMOS camera features outstanding low read out noise.

Even at maximum speed of 40 frames/s at full resolution of 2048 x 2048 pixel the noise is 0.8 e- (med). Moreover the pco.edge provides an excellent homogeneous pixel response to light (PRNU, photo response non-uniformity) and an excellent homogeneous dark signal pixel behaviour (DSNU,dark signal non-uniformity) which is achieved by a sophisticated electronic circuit technology and firmware algorithms.

high resolution

The pco.edge sCMOS camera features outstanding low read out noise.

A 4.2 Mpixel resolution in combination with a moderate chip size (18.8 mm diagonal, 6.5 µm pixel pitch) benefts microscopy applications with low magnifcation factor and large feld of view, thereby reducing processing times and increasing throughput. The figure compares the potential of the new feld of view of the pco.edge to the 1.3 Mpixel image resolution which is widely used in microscopy applications for scientifc cameras

rolling shutter readout modes

pco.edge sCMOS cameras feature a variety of precise synchronization modes which are optimized for advanced microscopy imaging and scanning.

The flexible frame and line triggers with very low latency and, in combination with the free selectable readout modes, can easily be combined to cover every modern microscopy situation

For example, one mode is used in a lightsheet or SPIM application, the lower right rolling shutter operational mode “single top down” operation is convenient to properly synchronize the camera exposure with the scanner. On the other hand, if speed is required and a ?ash like exposure is applied the upper left mode “dual outside in” is used for localization microscopy techniques like GSD, PALM or STORM.

free of drift

The pco.edge sCMOS cameras feature temperature stabilized Peltier cooling. This allows for continuous drift free operation in image sequences capture. This is achieved by the proper selection and sophisticated combination of electronics and FPGA algorithms.

As the measurement result shows while running at full speed of 100 frames/s over 4 hours measuring time the camera doesn’t show any signifcant drift. This degree of stability enables long-term measuring series, which should be quantitatively evaluated and processed. For example, in PCR (Polymerase Chain Reaction) applications, when so-called melting curves must be measured, the fuorescence in multi-well plates with different samples is recorded over a longer time at different sample temperatures. Here all the images are used for processing, which is only possible if the offset is stable and the camera is free of drift.

flexibility and free of latency

User selectable choice of rolling shutter modes for exposure provides fexibility for a wide range of applications.

The advantages of rolling shutter are high frame rates and low read out noise. Due to realtime transmission of the image data to the PC, there is no latency between recording and access or storage of the data.

37500:1 dynamic range

Due to the excellent low noise and the high fullwell capacity of the sCMOS image sensor an intra scene dynamic range of better than 37500:1 is achieved.

A unique architecture of dual column level amplifers and dual 11 bit ADCs is designed to maximize dynamic range and to minimize read out noise simultaneously. Both ADC values are analyzed and merged into one high dynamic 16 bit value.
