Shining a light on intensified imaging

Keely Portway investigates how the latest developments in specialised intensifier cameras have allowed opportunities for a number of exciting specialist applications in low-light scenarios

Image intensifiers help to increase the intensity of the available light in a system, which allows better image reproduction in low-light scenarios. This specialist technology is used in a range of applications, including biotechnology, industry, research and astronomy.

Optimizing your OCT Spectrometer Design: The mysteries of roll-off explained

This article is brought to you by: 

Does building your own OCT spectrometer really get you the clearest image? Creating a high-performance spectrometer for SD-OCT imaging requires a deep understanding of the finer points of both OCT theory and spectrometer design. In this tech note, we'll explain the most important parameters and contributors, then model the best available off-the-shelf lenses vs custom-designed optics to see just how the two compare. The difference in performance will surprise you…
