A new simple chip powered by quantum dots allows standard microscopes to visualise difficult-to-image biological organisms.

MIT researchers have developed a multi-layered chip that could dramatically reduce the cost of dark-field microscopes

Focuslight technologies, a global provider of high power diode lasers and micro optics, announced the LIMO Wide Angle Diffuser at SPIE Photonics West 2020. Designed for automotive LiDAR and 3D sensing applications, the LIMO Wide Angle Diffuser is a glass refractive optical element (ROE) with the ability to disperse laser light in one direction up to a full illumination angle, ranging from a few mrad up to 150 degrees. When combined with a second functional surface, the light can also be shaped at any desired angle in the other direction.

Focuslight technologies, a global provider of high power diode lasers and micro optics, announced the Focuslight FocusFlux® AL01 Series LiDAR laser module at SPIE Photonics West 2020. The FocusFlux AL01 series is a high peak power, 1064nm laser module that employs a novel, compact, solid state design. It features a 1.5mJ 3ns laser pulse based on Q-switch technology. Built-in advanced glass diffusers enable it to generate a configurable field of view (FOV) of 125x25, 60x45, or customized per request.

The European Space Agency’s Laser Interferometer Space Antenna requires very-low-noise seed lasers

Professor Emir Salih Magden updates on plans to commercialise an on-chip broadband optical filter announced last year

Optical filters are encountered in nearly every aspect of the optics, photonics and imaging industries, featuring in applications such as spectroscopy, microscopy, lidar, astronomy and optical communications, in addition to a multitude of others.

The technique uses a nanostructure that ‘traps’ molecules from the air and amplifies the Raman signal

The high electrical current required to achieve the lasing process has made it difficult to create the devices up until now
