Proteins are the workhorse molecules of life. Among their many jobs, they carry oxygen, build tissue, copy DNA for the next generation, and coordinate events within and between cells. Now scientists at the University of North Carolina at Chapel Hill have developed a method to control proteins inside live cells with the flick of a switch, giving researchers an unprecedented tool for pinpointing the causes of disease using the simplest of tools: light.
Researchers at Aalto University in Finland have demonstrated for the first time a new lasing technique operating at visible light frequencies, in both bright and dark modes, by utilizing metallic nanoparticles arranged in a periodic array. Their findings make possible the creation of small and ultrafast on-chip light sources.
Iridian Spectral Technologies has developed filters and coatings for many satellites and low-earth orbit instrumentation for both terrestrial and stellar observation. This includes large format filters for astronomical observations (single band and multi-band pass filters), light absorbers/black coatings, dichroic mirrors and beam-splitters, and multi-element arrays.
Iridian Spectral Technologies has designed and manufactured a wide range of dielectric optical filters for imaging and machine vision applications. Featuring steep edges, high transmission values, and high durability, these color filters can be used to improve contrasts, and isolate spectral regions and colors in images.
The Nexview™ 3D optical profiler microscope stands out amongst competitive products by its ability to measure the topography of virtually any surface, irrespective of roughness, large steps and segments, thin films, steep slopes, with feature heights ranging from < 1 nm up to 20000 µm. It does all this in 3D, without contact, and provides the best qualities of other profiling technologies (stylus, confocal, focus scanning) without their limitations.
Hyperspectral imaging (HSI) is used for many applications including satellite imaging and air reconnaissance. HSI is usually executed with bulky hyperspectral-imaging cameras that are sensitive to misalignment, very expensive, and use prisms or gratings as dispersive elements. An alternative method of HSI is the combination of linear variable bandpass filters (LVBPFs) with silicon detectors. This allows for very compact, robust, and affordable HSI detectors that offer several advantages over conventional approaches.
High-speed camera users demand cameras that work accurately under the harshest environmental conditions, making reliability and operational capability crucial considerations in scientific cameras. This video shows a combustion analysis application, using a pco.dimax high-speed camera, at the Robert Bosch GmbH in Stuttgart. PCO’s camera acquired exceptionally detailed images due to its sensor’s superior light sensitivity, despite poor lighting conditions.

Pyroelectric detectors are used in many types of IR detection applications where the key to the performance is the signal-to-noise ratio of the sensing element or detector. Since pyroelectric detectors are high output thermal devices, the noise output is typically the limiting item to their performance. This application note discusses the various sources of noise in these devices and how it can affect the performance in each application.
LASER COMPONENTS looks to provide background information on the multiplication process in Silicon used in the materials for fabrication of PIN and Avalanche Photodiodes (APDs) for visible and near IR applications. This application note presents approaches to designing APDs, as well as other helpful information on the use of APDs.
PCO-TECH looks to debunk the myth that “large pixel image sensors are always more sensitive than small pixel sensors.” This article describes, in detail, the relationship between an image sensor’s pixel size and its sensitivity, and how each defines the quality of an image.
PCO has launched its new high-speed series of pco.dimax cs cameras, adding three new models to its portfolio.
