At less than half the length of Laowa's existing 15mm f/2 lens, the new f/5 version looks like an ideal travel companion ...

Instead of trying to make an air-tight piston, he added a rubber membrane and a clever valve system to create a diaphragm air engine. This GIF is worth 115 words A round rubber diaphragm with a ...

Diaphragm pumps are positive displacement pump which move gases, liquids, or gas-liquid mixtures via a reciprocating diaphragm. They are highly reliable because they do not include internal parts that ...

Plication of the diaphragm is performed for paralysis or eventration (abnormal elevation/shape) of the diaphragm which can result in breathing difficulties. Diaphragm paralysis is typically due to ...

The multidisciplinary study of the transmission of light through the ocean, including the development and use of novel imaging technologies. Research interests are broadly concerned with the use of ...

Construction consists of 8 elements in 7 groups, with a 9-bladed diaphragm providing a minimum aperture of f/22. Sharpness and contrast are excellent at f/8 across most of the frame, and chromatic ...

(The ND filter cannot be enabled with the diaphragm wide open.) The following table reflects the maximum and minimum apertures as reported by the camera at popular approximate focal lengths ...

Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which ...

The RF 24mm F1.4 L VCM and RF 50mm F1.4 L VCM are part of Canon's new 'hybrid' series of lenses designed to work with both EOS and Cinema EOS cameras.

Canon's newest, non-extending 70-200mm F2.8 L zoom for RF-mount includes features aimed at both photo and video shooters. It also works with Canon's RF-mount 1.4x and 2x teleconverters.

The authors expand the dimension of non-Abelian Thouless pump from 1D to 2D and realize it using laser written photonic waveguide arrays, which serve as a promising platform for probing non ...
