Astronomical optics at the largest telescope in Eurasia
Rostec has completed the installation of a mirror at the Large Altazimuth Telescope (BTA) in the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) in Karachay-Cherkessia. The telescope with updated astronomical optics, which increase the range of observations 1.5 times, will begin working this fall. The key element of BTA installed by Rostec experts is a mirror with a diameter of 6m.
Hybrid gym makes savings with energy efficient LED lighting
The LED lighting brand, Goodlight, has announced that CrossFit Perpetua, a dedicated hybrid gym is set to make up to 70% energy savings following the replacement of its old fluorescent lighting, with long life, energy efficient G5 LED Battens from the Goodlight range. Return on investment is expected within 18 months.
LED grow light chosen for indoor lettuce greenhouse project
Developer of LED technologies and horticultural grow lighting, Plessey, has announced that B4Hydrogrow, a new venture from Dutch lettuce grower B-Four Agro, will install Plessey’s new Hyperion 1750 micromole/s LED top-lights in its first greenhouse measuring 29,000m².
On-chip optical filter processes wide range of wavelengths
MIT researchers have designed an optical filter on a chip that can process optical signals from across an extremely wide spectrum of light at once, something never before available to integrated optics systems that process data using light. The technology may offer greater precision and flexibility for designing optical communication and sensor systems, studying photons and other particles through ultrafast techniques, and in other applications.
wysiwyg Release 41 adds exciting features, improves workflow
CAST Software has announced the release 41 of wysiwyg lighting design and previsualisation software. The new version brings a broad range of new features and functionality that they hope will reinforce wysiwyg’s position as the tool of choice for lighting professionals.
Fibre tips with ball lenses for end-face processing
LASER COMPONENTS have provided custom ball lens profiles on the end faces of silica fibres. The plasma-based CMS process with ring-of-fire technology supports fibre diameters of 200, 365, 400, 550 and 600μm, including other diameters within the limits of the equipment. For fibres used in medical applications, end-face processing can be carried out in a clean room in accordance with ISO 13485. The entire process is also comp...
Never fumble for a hotel light switch again
The smart hotel of the future got a step closer today with the launch of Interact Hospitality from Signify. The hotel room management system enables guests to alter lighting, temperature and make room service requests at the touch of a button. This smart system also lets hotel staff know if a room is occupied and helps them to respond quicker to guest requests, providing useful information to improve the guest experience, optimise operations and ...
Custom sapphire lenses designed to endure harsh chemicals
Custom sapphire lenses that are impervious to blood, harsh chemicals, and chlorine and fluorine gas for use in a wide range of medical sensors and instruments are available from Meller Optics.
Optical fibres can 'feel' the materials around them
EPFL researchers have developed an optical fibre capable of detecting what sort of material or liquid they have come into contact with. Their research has been published in Nature Communications. In recent years optical fibres have served as sensors to detect changes in temperature, like a thermometer, and pressure, like an artificial nerve. This technique is particularly useful in structures such as bridges and gas pipelines.
Sensor module for embedded video applications
It has been announced that Sunex Optics has released its first sensor module, the MOD255I, based on its 4K Miniature DSL255 SuperFishEye Lens for easy digital video device development with embedded vision.
