Some will go on to point out that Europe has scopes with objective lenses
as big as 72mm for these specific scenarios.
* Increase the separation between the eyepiece and objective lenses
: incident vergence from a near object may be corrected as it travels through the telescope by increasing the separation between both the eyepiece and objective lenses
(see Figure 6B).
The effects of three variables were considered: (1) magnification, which was changed using various objective lenses
and which also influences the lateral resolution (see Table 1); (2) medium, which was air or water; and (3) water flow rate.
Furthermore, the research report has divided the objective lens market in Africa on the basis of type into objective lenses
for cameras and projectors and other objective lenses
To date, objective lenses
in the 20mm range have been the standard on most micro red dot sights.
Both microscopes have the Auto Link Zoom feature, which automatically adjusts to maintain the same field of view when switching objective lenses
, supporting seamless viewing at different scales.
The advanced hardness tester has multiple objective lenses
and indenters and intuitive software to assist the operator in setting up test routines.
Why not just buy high-power binoculars with big objective lenses
, say the above-mentioned 8x42 (5.25mm exit pupil), or a 10x50 (5mm exit pupil)?
Both models feature 40 mm objective lenses
and are offered in Mossy Oak Brush, Real tree Max-1 and matte black.
In addition, the entire spectrum of proprietary objective lenses
can be used with a consistently high optical section quality.
The DuraScan can have up to a six-position automatic turret with multiple indenters and objective lenses
, eliminating the need for manual exchange, consequently reducing frequent recalibration of the machine.
