"Lanthanum-based catalysts are used to refine petroleum. Cerium-based catalysts are used in automotive catalytic converters"

"Magnets that employ REEs are rapidly growing in application. Neodymium-iron-boron magnets are the strongest magnets known, useful when space and weight are limiting factors. Rare-earth magnets are used in computer hard disks and CD–ROM and DVD disk drives. The spindle of a disk drive attains high stability in its spinning motion when driven by a rare-earth magnet. These magnets are also used in a variety of conventional automotive subsystems, such as power steering, electric windows, power seats, and audio speakers."

Laserintensity calculator

Using 633 nm of a He-Ne laser as the reference wavelength, this instrument enables direct reading of the optical power of visible-range laser light from a visible laser source - pointer, DVD player’s optical pickup, etc. The power of other wavelengths can also be measured by converting the reading according to the spectral sensitivity characteristic table (typical values).

In this paper, we propose a deep learning based approach to convert RGB image sequences taken by regular cameras to (partial) hyperspectral images. This can ...

The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people.

"Rare-earth elements (REEs) are used as components in high technology devices, including smart phones, digital cameras, computer hard disks, fluorescent and light-emitting-diode (LED) lights, flat screen televisions, computer monitors, and electronic displays. Large quantities of some REEs are used in clean energy and defense technologies."

The Sanwa LP10 is a Digital Laser Power Meter that features a 4039 count LCD display with an analog bar graph. This is used in checking and maintenance of the optical power levels of equipment using laser light.

For each distance of the plant from the lamp, light intensity will be proportional to the inverse of d 2 , d 2 meaning distance squared.

"Specific REEs are used individually or in combination to make phosphors—substances that emit luminescence—for many types of ray tubes and flat panel displays, in screens that range in size from smart phone displays to stadium scoreboards. Some REEs are used in fluorescent and LED lighting. Yttrium, europium, and terbium phosphors are the red-green-blue phosphors used in many light bulbs, panels, and televisions. The glass industry is the largest consumer of REE raw materials, using them for glass polishing and as additives that provide color and special optical properties. Lanthanum makes up as much as 50 percent of digital camera lenses, including cell phone cameras."

Measurements only become meaningful when there is confidence in the accuracy and the quality of the instruments being used. Since 1941, Sanwa's mission has been to deliver the highest quality measuring instruments to its customers by placing customer trust and satisfaction first and foremost. As a result, Sanwa has built an unparalleled reputation for superior quality, design and safety in every multitester, clamp meter and component they manufacture.

The light sensor in this device is a silicon photodiode (light sensor surface diameter 9 mm) with a diffusion sheet. It can measure wavelengths within the 400 nm to 1100 nm range. The cleverly designed cover folds flat in back of the unit when in use, and protects the unit when closed.

A lens is a thin, curved piece of glass or plastic in something such as a camera or pair of glasses which makes things appear larger or clearer.
