The measurement of the acceptance angle of an optical fiber, which is the maximum angle at which the core of the fiber will take in light that will be contained within the core. Taken from the fiber ...

Ever see a photograph with a dreamy, out-of-focus background? Or perhaps a landscape with pin-sharp details from the closest foreground elements all the way to distant clouds? Aperture is what allows ...

The naming system can seem confusing at first: aperture settings are named for what fraction of the focal length the diameter of the hole is. This risks being confusing in two ways: firstly, a smaller ...

Setting your aperture is one of three keys to better and creative photos. The other two are your ISO and Shutter Speed. Do you want to create better, more creative photos? But, maybe you find the ...

Designed with new manufacturing technology that creates lenses with shapes that are difficult to fabricate using other methods, Olympus’ new X Line™ series objectives and the UPLAPO-HR objectives for ...

Here, we report a versatile soft x-ray diffraction microscope with 70- to 90-nm resolution by using two different tabletop coherent soft x-ray sources-a soft x-ray laser and a high-harmonic source. We ...

When reflecting on science and research, it is hard to find a technology that is as important as microscopy. Microscopy is not only of utmost importance as a tool for conducting research, there is ...

Flat optical devices thinner than a wavelength promise to replace conventional free-space components for wavefront and polarization control. Transmissive flat lenses are particularly interesting for ...
