Researchers have developed a way to perform optical coherence tomography (OCT) in hard-to-reach areas of the body such as joints
Notal Vision, an ophthalmic diagnostic services company, has started a clinical trial in the United States to advance the commercialisation of its home-based, patient-operated, spectral-domain optical coherence tomography (SD-OCT) system
Wasatch Photonics has expanded its Cobra OCT spectrometer product line to include new models for 550nm vis-OCT and long-range 800nm OCT imaging
Thorlabs has expanded its Ganymede OCT line to include two complete imaging systems offering an exceptional A-scan rate of 248kHz
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…
A team of Polish researchers has developed an optical coherence technology system capable of providing detailed images of the entire eye using electrically tunable lenses and a newly commercialised swept light source
A European research team has developed a handheld diagnostic scanner that can detect skin cancer in 30 seconds. It uses an infrared laser beam to identify blood vessels grown by malignant melanomas
David Creasey details Wasatch Photonics’ history with Jessica Rowbury and discusses the challenges and opportunities going forwards

As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
