The phrase "a range of focal" is not correct as it is incomplete and lacks context.
It could be used in contexts discussing various focal points or areas of focus, but it needs additional information to be meaningful.
Example: "The study examined a range of focal points in the research."
Alternatives: "a variety of focal" or "a spectrum of focal".
Due to correction requirements over a range of focal lengths, zoom lenses are complex systems containing from 12 to 20 elements.
When we check for a range of focal depths for autofocussing, is there any parameter that determines the min or max of this range or do we just make a guess and try a random range, and then keep narrowing it down?
Comparison of displacement magnitudes generated in a homogeneous material by acoustic radiation force excitations can be used to estimate the material's attenuation when the excitations are applied over a range of focal depths while maintaining a constant lateral focal configuration.
In a range of small focal lengths, the optical efficiency increases with the increase of focal length, and then decreases constantly with further increasing focal length.
The Zenmuse X7 camera has a large, Super 35 format digital sensor, and supports interchangeable lenses for a range of potential focal lengths.
A dynamic optical lens system with a combination of one DCX and multiple variable focal length DCV lenses as designed here can image an object with a wide range of focal length and FOV.
This patent can also scan over a complete range of focal lengths in only microseconds, much faster than the other variable focal devices on the market". Arnold worked with McLeod, who earned a Ph.D. in mechanical and aerospace engineering in 2009, and former postdoctoral researcher Alexandre Merminlodeveloping in developing the lens.
Our previously published larger genome-wide association study for a broader range of focal epilepsies did not identify any single-single nucleotide polymorphism association (Kasperaviciūte et al., 2010), but the findings here demonstrate that associated variants may exist for more narrowly-defined syndromes.
To determine this threshold, we compare the intensity of polyacrylamide gel-embedded fluorescent beads in uniform and HiLo-processed images at a range of distances from the focal plane (also called the imaging plane), which is approximately ten frames above the midplane of the image stack.
In a focal-plane shutter camera the usable range of focal lengths is practically unlimited.
Utilizing a range of 15 existing Mamiya 645AF focal plane lenses, the Mamiya DM22 and DM28 offer many of the features found on their higher-end siblings.
