The required throw ratio depends on placement of the product relative to the image surface
. A long-throw projection lens is typically defined as having a throw ratio greater than 2-to-l.
Among their topics are rays and ray sketching, how to put a lens in a computer, coma and astigmatism, aberrations of the image surface
, analyzing the performance of a lens, and building a lens.
In the secondary electron image surface
stains were observed at some breakdown sites (Figures 4 and 5) similar to those observed in  but at other sites no surface defects were revealed at the positions of type I breakdowns.
The exit pupil position is -20000 mm from the image surface
The problem is solved through the analysis of digital feather image surface
The ultra-variable pressure detector enables image surface
information at low vacuum and low accelerating voltages.
It is also important to validate the accuracy of satellite image surface
temperature data by comparing it to in situ surface temperature data.
And rather than stopping there, she further employs the canopy as an image surface
as well, incorporating a drawn trio of images depicting the titular evergreen shrub interspersed with images of butterflies flitting about.
Only 30% of the image surface
is visible, it's like looking at the tissue through a mask."
(19,20) This capability allows AFM to be used to image surface
morphology and surface heterogeneity based on local chemical interactions, making the linkage between physical properties and chemical properties possible at micro- to nanometer scales.
Wide-area Non-Destructive Inspection (NDI) imaging technology will allow inspectors to image surface
corrosion beneath paint, rapidly characterizing large aircraft parts quantitatively in a single session while easily documenting the results for comparison with future inspections.
Operating off a 110-volt outlet, there are no electronic components on the display's image surface
, making the screen more durable and impact resistant in environments where vibration and contact could damage it.
