Refrigerator and cooler cabinet LED lighting products
Ledtech UK, the UK arm of one the world’s largest capacity LED manufacturers, has announced a full range of LED lighting products for the retail refrigerator/chiller display cabinet market. Comprising units rated to IP54 and IP65, centre, end, shelf and canopy illumination units are available in a selection of lengths and diameters.
Laser optics help keep fruit and vegetables fresh
Diffractive Optical Elements (DOEs) allow laser beams to be split, bundled, or formed into almost any shape and are used in multiple applications. The food industry, for instance, uses them for laser perforation, when it comes to applying micro holes into packaging for fruit or vegetables. These allow the food to 'breathe' and thus extend its storage life. The holes have diameters of between 50-300μm depending on the type o...
Sensor manufacturer certified to global quality standard
Manufacturer of fibre optic kinetic sensors for industrial and medical applications, Micronor has announced that it has been certified under ISO 9001:2015 as of 5th March, 2018. The company earned certification from registrar TUV Nord USA.
Interference filters can absorb visible-NIR
Interference filters are widely used in a transmissive configuration, whereby light passes through the filter to cause some effect, be that band-pass, short-pass or long-pass etc. By nature, interference filters do not generally absorb in the visible-NIR, but instead light is either transmitted or reflected. That makes transmissive interference filters suitable for applications within this spectral range.
Pyroelectric detector uses a differential mode of operation
Pyroelectric detectors are susceptible to line interference and other sources of electromagnetic interference from non-detector related noise. Several manufacturers of OEM sensor devices use EMI filters to prevent these noise sources interfering with the operation of the device but for many gas detection applications a higher level of noise immunity is required.
wysiwyg helps build The Ark
What do a popular classical music show in London, an international swimming competition in Budapest, an outdoor rock concert in Belgium and a new church in a tiny village in England have in common? Simply: all have benefited from the use of CAST Software’s wysiwyg lighting design toolkit. With three churches already serving its population of 2,300, it’s perhaps surprising that one of them is building a new one in the fenland vill...
Pyroelectric detectors recombines beams and directs sample
Fourier transform infrared spectrophotometry has become a well-established alternative to dispersive spectrophotometry, using prisms or gratings. An FTIR interferometer splits one beam of light from a broadband source into two using a beam splitter, transmitting the first beam to a fixed mirror and the second to a mirror that is translated back and forth very precisely so that the paths of the two beams are different.
Imaging technique pulls plasmon data together
Rice University scientists have developed a novel technique to view a field of plasmonic nanoparticles simultaneously to learn how their differences change their reactivity. Their new method is called snapshot hyperspectral imaging (SHI), which up to now has been used primarily in astronomy. SHI allows researchers to view minute differences between otherwise identical nanoparticles and see how they react in response to light and environmental cha...
LED light bulb has been sent into space
Following news that a Swedish design brand has sent an LED light bulb into space as part of a crowdfunding campaign, lighting specialist BLT are highlighting the continuing evolution of the most progressive light source of the 21st century. The arc bulb has been designed by Flyte to be the ‘the ultimate minimal, dimmable LED bulb’ and has already exceeded its funding target of £17,000, with more than 900 backers signed up to rec...
Optical fibre gains ground for Gigabit Ethernet connectivity
KDPOF has announced a complete POF solution to be seamlessly integrated into the wire harness of the vehicle. At the International Congress Automotive Wire Harness on March 13 and 14, 2018 in Ludwigsburg, Germany, KDPOF will display innovative gigabit POF solutions in partnership with leading wire harness suppliers such as TE and others.
