TEM, or Transmission electron microscopy (also sometimes conventional transmission electron microscopy or CTEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample […]
With high-precision imaging, the food processing and beverage industry tests even hard-to-inspect products with absolute reliability. The result: 100% quality and ever-growing productivity. The need to manufacture products reliably, and without faults is more important than ever in the food, beverage and packaging industries. The pressure to achieve this has led to extremely high levels […]
The National Science Foundation’s LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational-wave detector have published new results from the first two observing runs. Four new black hole mergers have been announced. The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and […]
Rail inspection is the practice of examining rail tracks for flaws that could lead to catastrophic failures. According to the United States Federal Railroad Administration Office of Safety Analysis, track defects are the second leading cause of accidents on railways in the United States.
A new kind of precise and non-invasive imaging called optical coherence tomography angiography (OCTA) has assisted much of the recent research on the eye’s connection with Alzheimer’s. It enables physicians to see the smallest veins in the back of the eye, including the red blood cells moving through the retina.
Two decades ago, going through airport security was a simple process. You simply got into “the” line, put your stuff through the x-ray machine, and walked through the metal detector. Today, the process is much more complex, with as many as four different security lines at some airports, various levels of identity verification and screening offered, […]
Barcode scanners are extremely simple devices that can read and output printed barcodes to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the bar code’s image data provided by the sensor and sending the barcode’s content […]
While traditional lens is made from glass, metalenses use flat surfaces made up of nanostructures to focus light. These simple, flat surface lenses could replace bulky, curved lenses currently used in optical devices.
The use of license plate readers is increasing in popularity with police and other law enforcement agencies to find stolen cars and catch up with people with expired licenses or active warrants. And when they’re not piggybacking on police cruisers, plate readers are often affixed to utility poles or freeway overpasses, scanning the passing traffic […]
M12 Lenses, also referred to as S-Mount Lenses or Micro-Video Lenses, are board lenses used to focus an image onto a camera sensor. They are used in a variety of applications including automotive, forensics, pharmaceutical, and food inspection. These S-Mount Lenses are compact imaging lenses designed for use with many small format industrial cameras. M12 […]
