Carbon dioxide is both invisible and dangerous, but with a new generation of infrared lights, the cloak may be lifting. CO2 buildups often happen at a crawl, and in many confined places (some that may seem more obvious than others), the issue is of constant concern. Detection devices and alert systems are deployed in places…
For some time now, the capability of light cells to distribute power and connection to IoT-based (Internet of Things) devices has been clear. Predictions and theories no longer seem like idle chatter as fully-functional LED units are now showing proof of concept and are capable of connecting IoT devices. LED units such as these made…
Deriving from our high expectations, the OL 458-4 White LED-based calibration standard is an elite measurement unit. This fixed luminance sphere was created to provide hyper-accurate optical readings for a wide array of instruments. Those instruments include, but are not limited to: Micro and Telephotometers Image intensifiers Imaging photometers and colorimeters intended for photometric, radiometric,…
When optical scientists talk of turning light upside down, they aren’t merely thinking of hanging a light bulb in a garage. A more accurate description of this technique would be: the intentional subversion of the hyperbolic metasurface from which light pushes outward. Of course, that’s not really clear either. Optical science and calibration standards are…
It’s easy to espouse the virtues of LEDs, as there are many, and they often show themselves in unconventional situations. From diodes that assist in mosquito control to those that reduce carbon emissions, the more esoteric uses of LEDs have become very common. To make all of this possible, photometric standards are of the utmost…
Light displays are a constant in modern life, so much so that they can often become an afterthought. But the quality and reliability of any display, as smooth and straightforward as it may seem to the user, did not get that way by simple chance: it arrived through constant testing and a battery of calibration…
The human brain is a complex organ that has challenged scientists for centuries. They often struggle to find suitable treatments for an array of maladies. But over the years, there has been progress: unique items such as fiber-optic probes have become options for those with diseases such as Alzheimer’s, or serious injuries. However, to date,…
