Everything You Always Wanted To Know About sCMOS Cameras – But Were Afraid To Ask

Everyone has questions that they are too afraid to ask. If this is the case for sCMOS cameras, this eBook by PCO is designed to help answer these questions. Whether it is questions relating to pixel size, camera sensitivity, industry standards, or data transmission, this information is meant to be helpful and fun to read.

What Is All The Hype About Resolution And Mega Pixels Anyway?

Resolution, in the context of an image sensor, describes the total number of pixels utilized to create an image. The question is then why does pixel count matter? This white paper discusses the importance of resolution and its relevance in camera systems with image sensors.

Is It True That Cooled Cameras Are More Sensitive Than Non-Cooled Cameras?

Temperature can have significant impact on noise sources prevalent in cameras, which contributes to the total readout noise of an image sensor. As such, the reduction of temperature through “cooling” of image sensor components or electronic circuits can improve image quality and performance. However, the advantages and disadvantages of cooling reveal that cooled cameras may not necessarily be more sensitive than non-cooled cameras. This paper will examine the underlying effects of cooling in cameras and their sensitivities.

Understanding A Camera’s Resolution

The resolution of an image sensor describes the total number of pixels that can be used to detect an image. From the standpoint of the image sensor, it is sufficient to count the number and describe it usually as the product of the horizontal number of pixels times the vertical number of pixels.

Are Larger Pixels Always More Sensitive?

A common myth is that larger pixel size image sensors are always more sensitive than smaller pixel size image sensors. To explain that this isn’t always the case, this paper will look at the effect that the pixel size has on image quality, especially for the overall sensitivity, which is determined by the quantum efficiency. 

Dynamic Range: What Is It Good For Anyway?

Since many camera manufacturers define dynamic range from a different point of view, a distinction should be made between the “dynamic range of an sCMOS, CMOS, or CCD image sensor,” “dynamic range of an analog-to-digital-conversion,” “usable dynamic range,” and “maximum dynamic range or SNR.”
