The lenses of
INFINITY: PROXIMITY¢â
Series
InfiniMini¢â InfiniMite¢â
InfiniStix¢â
InfiniTube¢â
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.

InfiniMini¢â
Video/Machine Vision Lens
(.pdf )
available in¡¦
two different versions: InfiniMini InfiniMini-IND
Both InfiniMini share the
same optical characteristics and accessories in common with each
other ?the only difference being its overall diameter, type of focusing-lock?and
designed for the specific requirements of video/machine vision system
integrators.
------------------------------------------------------------------------------------
InfiniMini¢â
("Reference" Series) - Revolutionary, internal-focusing
video/machine vision lenses that offer a choice of four rear converter
systems. When equipped with the Standard Converter, InfiniMini focuses
directly from 750mm down to 150mm (30 in. to 6 in.) at 0.07x to
0.37x. With the IF Converter, InfiniMini focuses directly from infinity
down to 314mm. Equipped with the SF Converter, InfiniMini can be
utilized with video cameras having sensors 1/3 in. and smaller.
The WA Converter is the same size as the SF Converter and operates
from 550mm to 150mm and provides wide fields, particularly with
1/3-in., and smaller formats. Regardless of the converter used,
InfiniMini progressively corrects its optical performance during
focus. In fact, InfiniMini actually transitions between being a
telescope and a microscope!
With optional accessories, InfiniMini can be focused from infinity
down to 10mm at 8.0x. Accessory amplifiers of (2x, 4x) extend the
configurational magnification ratio to more than 130:1. InfiniMini
is only 98mm long and 35mm diameter. It is fully compatible with
all C-mount and CS-mount video cameras. Add to that, its internal-focusing
capability, extremely long working distances, illumination accessories
and a starting price under $700?and you have what we believe to
be (within its "design envelope") the world¡¯s finest machine
vision lens.
Input from machine vision specialists was taken into consideration
during the design and development of InfiniMini, resulting in a
truly innovative video lens with many unique features. Incorporating
a patented Dynamic (internal) Focusing System (DFS¢â), InfiniMini
always remains dimensionally-stable. InfiniMini¡¯s DFS system provides
continuous spherical correction with progressive proximity to the
subject. This means that InfiniMini improves its image quality where
other lenses suffer aberrational defects. As InfiniMini is focused
from anywhere within its focusing range, blurring is equal on both
sides of a sharp focus?regardless of the selected working distance.
InfiniMini-IND¢â (Industrial)
- A smaller diameter (33mm), variable and quick-lock InfiniMini
designed to fit into machine vision/video housings, etc. Aside from
that, the IND is optically identical?and in all other respects,
the same as the (above) InfiniMini.
------------------------------------------------------------------------------------
FOCUSING-LOCK
TYPES:
Variable / Friction Lock (InfiniMini
"Reference" Series )
The Reference Series InfiniMini lenses contain an integral Focus-lock
that operates as a friction brake. This type of focusing mechanism
facilitates easy "back and forth" adjustments (via its
ergonomic knurled focusing ring) whenever frequent re-focusing is
necessary, yet offers the ability to lock it at any desired focus.
Variable / Direct Quick-lock (InfiniMini-IND)
The Industrial version, InfiniMini-IND, offers the versatility of
variable focus, but with the simplicity of its quick-lock focuser.
Designed to fit into machine vision/video housings, etc., the (smooth)
focusing ring on the IND is meant to be locked at one focus, but
may be conveniently re-set (by a sliding set-screw adjustment) if
the need arises. This "set and forget" type of system
reduces the chances that its focus will be knocked out of position
or tampered with, yet also offers the versatility of variable focus
when needed.
------------------------------------------------------------------------------------
The CFM
ATTACHMENT:
The CFM Attachment permits the InfiniMini to alter magnification
with distance, thereby setting the best compromise of magnification,
working distance and depth-of-field. Entire circuit boards, for
example, can be held and rotated, while at the same time, being
held completely in focus. Then, a specific detail may be zeroed-in
at truly microscopical magnifications, providing primary magnifications
from 0x to 4x and can be continuously focused from infinity down
to 10mm. Put in terms of a ¨ö", format video camera and 13-in.
monitor, this means that a CFM-equipped InfiniMini provides continuous
magnification from 0x to 160x. By simply adding a 2x DL or LDL (lockable
onto the camera) doubler, magnification can range from 0x to 320x.
Additionally, a plastic probe tip
which permits 21mm fiber optic ring light to be moved up or down
its shaft, thereby attaining transitional effects from brightfield
to darkfield, this facilitating edge detection for measurements.
------------------------------------------------------------------------------------------------
System integrators want a simple, cost-effective
solution that is fool-proof, simple, yet versatile?the InfiniMini
is that. Lenses from other manufacturers would require constant
removal, disassembly and accessorization in order to even approach
the InfiniMini¡¯s capabilities. With three different InfiniMini main
models to choose from, video/machine vision systems integrators
now have the features, versatility and options they¡¯ve been asking
for?without the complexity?not to mention, the extremely attractive
prices
