Use the depth-of-field
preview (if your camera has one) to check the range of focus at your chosen aperture, before pressing the shutter button.
For embedded solutions, the company's technology can achieve a depth-of-field
image capture distance from 150mm up to 600mm in a single shot using one element lens.
The VHX Series Digital Microscope from KEYENCE was designed to alleviate the shortcomings of traditional, optical light microscopes--shallow depth-of-field
, short working distance, lack of portability/versa-tility, sample limitations, etc.
with the 7x lens is ideal for macro videos.
Recent optical design advances have resulted in an increase in the V2's field-of-view (FOV) and depth-of-field
Features include subpixel antialiasing, true displacement, motionblur, depth-of-field
, support for NURBS, subdivision surfaces, particles, and ray tracing.
The VHX-600 digital microscope is said to offer a large depth-of-field
that is at least 20 times greater than conventional microscopes.
25 inches with excellent depth-of-field
(according to the manufacturer).
The laws of physics and optics have always set frustrating restrictions on photomicrography: depth-of-field
under high optical magnification is minimal at best, and even worse when lens apertures conducive to maximum photographic sharpness are employed.
Focus is subjective, and to quantify what is meant by focus, the concept of circles of confusion is used, corresponding to the out-of-focus circles formed by light rays from outside the depth-of-field
Olympus Optical of Tokyo, also is licensing the Boulder company's technology for use in extended depth-of-field
endoscopes, which are camera-equipped catheters that doctors use to look inside a patient's body.
It can be used to label slides with accession numbers, divide slides into grids for multiple specimens, circle specimens for rapid depth-of-field
focusing, and dot cover glass to identify points of interest.
