About EMVA1288

The EMVA1288 is a standard for the specification and measurement of machine vision sensors and cameras, which has a significant benefit for a CCD, CMOS or sCMOS camera user.

Why are there special interfaces for the transmission of image data?

As camera technology has evolved, so have the interfaces used to extract image data from a camera and transmit it for storage and processing.

Raman spectroscopy enhanced by a back-illuminated sCMOS camera

This article discusses the challenges inherent in working with older detector technologies, dispels some misconceptions associated with Raman spectroscopy detectors, and introduces readers to PCO’s back-illuminated camera solutions.

What are all the discussions about global vs. rolling shutter?

Both versions have their individual benefits and disadvantages. But is one generally "better" than the other? How to decide which one to use? This article answers these questions by tracing the development of the two shutter modes.

New Intensified sCMOS Camera Technology Improves High-Speed Analysis

“Blink and you’ll miss it” — the phrase is synonymous with events that may occur too quickly for the human eye to discern. High-speed video has enabled us to record and analyze these events with increasing accuracy and clarity. However, some phenomena encountered in scientific and engineering analysis occur too fast for traditional video or photography to capture, and thus require an approach superior to traditional high-speed video. Intensified sCMOS provides the technical solution when other imaging technology does not meet your application’s high-speed requirements, whether you need ultra-short exposure times or higher resolution, and an extinction ratio beyond what non-intensified CCD or CMOS cameras can achieve.

Are large image sensors a perfect fit for large field of view microscope applications?

In the last years nearly all microscope manufacturers used image circles with 18 mm diameter to image their field of view to cameras connected to their microscopes. Only recently some microscope manufacturers increased their field of view to offer more information to their customers. However, this also resulted in larger image circles to be covered by cameras with their image sensors. Therefore, a run for cameras with appropriate image sensors started, and soon large image sensors were advertised, such that the questions arose: are larger image sensors a perfect fit for large field of view microscope applications. Before the question can be answered, we should have a look to the relationship between resolution, magnification, spectral range and pixel size of image sensors.

About resolution

The resolution of an image sensor describes the total number of pixel which 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 product of the horizontal number of pixel times the vertical number of pixel which give the total number of pixel, for example...
