The lenses of
Although we may at times refer to
Proximity lenses as instruments in the generic sense, they are ultimately
application-specific lenses (as opposed to systems). Infinity¡¯s
main product line of instruments (those without the Proximity logo)
are full-fledged instrument systems, (systems being the keyword).
They may be more adaptable and afford greater range of options and
customization than Proximity lenses. However, within their ¡°application
envelope,¡± Proximity lenses out-perform anything comparable.

With the exception of InfiniTube-Z
which must be used with Zeiss objectives, all other models can be
used with suitable Infinity Photo-Optical objectives (IF-Series,
LWD-Series, LWI-Series and the new Achrovid-Series. The EX has its
own line of objectives). All InfiniTube models are also designed
to accept most Model KC accessories, including Coaxial Illuminators
as well as 2x and 4x amplifiers.
The InfiniTube Standard is a 200mm
optic that, combined with infinity-corrected microscope objectives,
provides superb image quality at high magnifications. It is essentially
a fixed-focus version of Model KC and can accept most of its accessories.
The InfiniTube Standard is color-corrected for use with infinity-corrected
objectives obtainable from Infinity Photo-Optical Company (IF-Series,
LWD-Series, LWI-Series and Achrovid) as well as those offered by
Mitutoyo, Olympus and Nikon. In particular, the InfiniTube Standard
couples to our Coaxial Illuminator, providing self-condensed illumination
of highly reflective, flat objects. The InfiniTube Standard is a
cost-effective way to solve high-magnification imaging problems.
InfiniTube-VF takes the InfiniTube
concept one important step further by offering Variable Focus (VF)
capability. By turning its focusing ring, InfiniTube-VF can be used
to translate focus above, through and below a starting point?all
by Infinity's patented Dynamic Focusing System's (DFS) internal
focus. This means that InfiniTube-VF may be used in many setups
where a translation device would otherwise be required, yet the
outer dimensions always remain constant. InfiniTube-VF accepts the
regular InfiniTube accessories, including all adapters, filter holders
and the Coaxial Illuminator, and can be used with Infinity's LWD,
LWI and Achrovid¢â objectives, as well as those made by Mitutoyo,
Olympus and Nikon.
Finally, users of Zeiss ICS-corrected objectives can now mate them
to an InfiniTube system. InfiniTube-Z is identical in size and general
construction to the Standard model, but has color-compatible correction
for use exclusively with Zeiss ICS objectives.
Sometimes it is not possible to fit
the Standard InfiniTube into space-restricted machines or fixtures
that were built without consideration for adding a high magnification
video system. Or, technical considerations necessitate the smallest
possible lens that can be added. To meet these demands, Infinity
has developed the InfiniTube Compact. Only 67mm long, the InfiniTube
Compact provides comparable performance to the Standard.
For those requiring dual-port capabilities, the InfiniTube is now
available with a self-contained beam-splitter. The Dual-Port InfiniTube
permits photo and visual accessories to be coupled, besides the
usual C-mount video connector.
Designed for low magnification requirements,
the EX is nearly a universal solution for widefield to coaxially
illuminated video imaging.
