Now... with REVERSO™ Option
The original winner of both the R&D 100 and Photonics Circle of Excellence
awards in the same year has been brought to a new level of performance. InfiniVar
CFM-2/S is now infinity-corrected and can be optionally equipped for the
REVERSO macro mode (see below). In addition, its resolution has been increased c.25%
over the previous model.
Infinity-correction and increased resolution combine to make the InfiniVar CFM-2/S
the most versatile and comprehensive video microscope available.
InfiniVar CFM-2/S
Continuously-focusable from infinity down to 18mm, the InfiniVar CFM-2/S attains
9x primary magnification at its closest focus and, at 60mm, provides 1x primary
magnification on-sensor. Consequently, a movement of only 40mm equals a 9:1 zero-in
ratio. Moving InfiniVar CFM-2/S out further, a 36:1 zero-in ratio is possible from
180mm down to 18mm. Such adaptability allows the depth of field and magnification
to be combined for the best overall effects. InfiniVar CFM-2/S lets you
select the magnification, working distance, stand-off, resolution and depth of field
you wish—for a totally new experience in video microscopy.
Infinity-Correction
Infinity-correction not only provides the finest imagery, but also permits the alternate
use of two Infinity Cap Lenses provided with each CFM-2/S: Standard (STL)
and Compressor (CTL). Both Cap Lenses screw into the rear of the Main Body and are
conveniently user-interchangeable. The STL Lens provides the full range of 0-9x,
while the CTL Lens provides 0-5x. The CTL's range is particularly useful for image
processing at the highest possible resolution with larger objects or smaller format
(2/3-in. and less) sensors. In this way, the InfiniVar CFM-2/S is uniquely able
to match the resolution to the pixels of various camera formats. In effect, the
"lithography" of the resolution (the size of the Airy patterns) can be matched to
camera pixels and format simply by using either the STL or CTL Cap lenses. The results
are images of outstanding quality.
Accessorization
Dual-port and 50/50 Beamsplitter options allow up to two different cameras or other
rear tubes to be utilized with the InfiniVar CFM-2/S. Filters (e.g., polarizers)
can be mounted internally in the infinity-beam, so that image quality is not sacrificed.
Amplifiers can be added either for C-mount (DL 2x and LDL-lockable 2x) or for universal
formats (TX Tube). Please see the Price List for the ongoing accessorization program
which makes the InfiniVar CFM-2/S a true SYSTEM instrument.
REVERSO
InfinVar CFM-2/S in REVERSO mode
The Standard Mode is only ONE of the InfiniVar CFM-2/S configurations. The other
is, literally, 180-degrees opposite: REVERSO. InfiniVar CFM-2/S can be FLIPPED and
reconfigured for REVERSO mode. All that is required to convert from Standard to
REVERSO mode is to add the REVERSO Tube and mount the REVERSO Tube Lens in place
of STL or CTL Cap Lenses. Once focused, translation from a fixed point
("up and down") is made by the CFM-2/S' patented (additional patents pending) internal
focusing system WITHOUT SIGNIFICANT MAGNIFICATION increase or decrease—if
there is any variation at all. This makes the REVERSO mode ideal for "montage" and
other high depth of field techniques as well as critical measurements of industrial
objects from fixed positions—anywhere from infinity down to 20mm at 1.4x.
