Nanosilica Filled Epoxy with High Abrasion Resistance
Master Bond EP30NS is a two component epoxy system that cures at room temperature or more rapidly at elevated temperatures. It is optically clear especially in thin sections and can be used as an adhesive, sealant, coating and encapsulation compound. EP30NS offers dimensional stability, linear shrinkage of less than 0.01%, excellent physical strength characteristics and cures rigid. Most significantly, this epoxy system has been independently tested per ASTM D4060-14 for abrasion resistance for 1,000 cycles and exhibited a loss of weight of only 18.3 mg. This value exceeds typical epoxy compositions and demonstrates the compound's ability to withstand exposure to scuffing, gouging, scraping, scratching and wear.

Fast Production Test of UV-LEDs
Numerous applications, for example in the medical area or in material testing, are based on precisely specified UV radiation. For UV-B and UV-C emitters, the measurement of their spectrum between 325 nm down to 200 nm is generally only possible with extended measurement times due to their low radiant flux. As such, a condition for fast testing within production is high reliability in conjunction with high optical throughput of all participating system components. Within its well-established CAS-series of premium spectroradiometers over many years, Instrument Systems has developed a novel series-type CAS 140D-157. This new system measures precisely and reliably not only within the visible spectrum, but also in the UV. Coupled with a PTFE-coated integrating sphere, the system permits for fast 24/7 production tests of UV emitters to be run.

Pollinators: Switch Street Lights off at Midnight to Help Moths and Nocturnal Wildlife
Conservation is often a conflict between the demands of development and a desire to do what is best for the environment. It’s rare that we get the chance to report a decision which was taken for the good of people that has also panned out well for nature’s ecosystems. However, that is just what our new research paper found.

Luminus Gen 4 COBs: 70W CMH Spots Finally Meet Their Match
Luminus Devices latest, fourth generation chip-on-board LED technology (Gen 4) will open new opportunities in retail lighting and a wide range of indoor and outdoor lighting applications. Luminus Gen 4 COB technology combines significant improvements in efficacy, flux density, high maximum drive current, and high temperature capability to enable breakthrough changes in form factor for luminaire makers, For example, it is finally possible for a COB to deliver the output and punch of a 70 Watt ceramic metal halide lamp in an identical form factor. Luminus has eliminated the barriers that until now had required LED luminaires with comparable center beam candlepower to be larger than the incumbent CMH technology.

PerfectWhite: Luminus’ Latest Spectrally Tuned COB
Spectrally tuned sources are the essential components of human-centric lighting and Luminus PerfectWhite is it’s newest source, joining the Sensus and AccuWhite products, that has been purpose-designed and improves upon the light from conventional sources. PerfectWhite™, which closely replicates the visual characteristics of halogen lamps (3000 K) was preferred by lighting designers in testing at both Light + Building and Lightfair. Though the spectrums are a virtual match – Luminus filled the cyan gap – PerfectWhite’s color point is slightly below the black body locus and as a result, there’s no green/yellow tint that is common to halogen. A better halogen has long been a wish of the lighting design community and PerfectWhite delivers without infra-red, without green/yellow tint, and without ultraviolet radiation.

High Volume Laser Diode and VCSEL Testing
Hitherto established measurement technologies for laser diodes – such as dispersive scanning spectrometry and Fourier-transform infrared spectroscopy (FTIR) – can react sensitively to a production environment. High-resolution array spectroradiometers are effective alternatives that offer multiple advantages, also in continuous production.
Laser diodes, and in particular vertical-cavity surface-emitting lasers (VCSELs), have experienced rapid market growth due to new applications and new technological approaches. Examples of this are infrared VCSELs integrated into consumer electronics and direct diode lasers based on VCSEL arrays, replacing conventional laser systems.
