The company was founded in 2006 in Melbourne, Australia, [ 3] and also maintains offices in San Francisco and Berlin . The company operates primarily on the Internet and allows its members to sell their artwork as decoration on ...
Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations. When light waves travel through a medium other than a vacuum, interaction ...
Bright-field microscopy ( BF) is the simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light, and contrast in the sample is caused by attenuation of the transmitted light in dense areas of the sample.
Scientist using an optical microscope in a laboratory. The optical microscope, also referred to as a light microscope, is a type of microscopethat commonly uses visible lightand a system of lensesto generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present ...

Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
The phrase "Not now, Mama is drinking her special juice" just got a new meaning thanks to fruit cocktail empire Welch’s. This past spring, the brand known for its grape juice announced that it ...
Fluorescence and confocal microscopes operating principle. Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation.
