InfiniVar CFM-2/S

Now... with CentriTel in the 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 equipped as a CentriTel Macro Lens with the REVERSO Option (see below). In addition, its resolution has been increased c.25% over the previous model.

Infinity-correction, increased resolution and CentriTel capability 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 19mm, 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 19mm. 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 not only provides the finest imagery, but also permits the use of Infinity Tube Lens Systems which screw into the Main Body and are user interchangeable. The Regular Format Insert (RFI) is included with each InfiniVar CFM-2/S and accepts two supplied Cap Lenses:  Standard (STL) and Compressor (CTL). Both Cap Lenses screw onto the top of the RFI and are also 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.

The Large Format Insert (LFI) sets the InfiniVar CFM-2/S for use with sensors up to the 4/3-in. format. Then, by interfacing a supplemental TR Tube or TRT Tube (both optically identical, but the TRT is mounted in a T-sized tube which allows the Clamp to fit over it), InfiniVar CFM-2/S with LFI can be used up to 24 x 36mm formats (35mm size sensors). Consequently, the LFI can be equipped to function with virtually all DSLR cameras and scientific/industrial sensors. The LFI replaces the RFI in the InfiniVar CFM-2/S's Optics Module. Then, by adding the additional T58 spacer that is supplied with each LFI, the LFI maintains the full focusing range of the InfiniVar CFM-2/S from infinity down to 18mm, magnifying from 0-10x. Because the LFI can be used with almost any type of video or photo mount adapter, it is a universal format system, capable of being used with small or large sensors—without concern for compatibility.

By using either the RFI with Cap Lenses— or the LFI— 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 (technically, the size of the Airy patterns) can be matched to camera pixels. 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

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 essential magnification increase or decrease. This special condition qualifies the InfiniVar CFM-2/S as a CentriTel optic, 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.

The InfiniVar CF2/S represents the ultimate in video microscopy. No other instrument can do what it can do, and do it all so well. Contact us so that we can tell you how the InfiniVar CFM-2/S can solve your imaging problems.

REVERSO™ or HDF-2/S™?

Both of these Infinity Instruments are the finest macro systems you can choose.  But, which one?  Here are things to consider in your choice:

REVERSO is just one of InfiniVar CFM-2/S' functions.  If you have REVERSO, you also have the InfiniVar CFM-2/S to use in all of its other configurations.  CentriTel® is a direct function of the REVERSO mode.  Although REVERSO can not be used with accessories such as mirror diverters or supplemental zoom modules, it is compact and very well suited to laboratory and industrial mounting needs.  

HDF-2/S is Infinity's premier macro modular optic.  It is directly able to cover formats up to 24mm x 36mm — the traditional 35mm SLR format.  In fact, it can be equipped to cover any format used in macroscopy–even to 8 in. x 10 in. sheet film cameras.  Because the HDF-2/S incorporates an iris diaphragm for aperture and light-reduction control, it   may be thought of as the ultimate classic macro camera lens, brought to the level of being a true instrument in its own right.  Unlike common macro camera lenses, its extraordinarily long back tube length facilitates dual-port mirror diverters, zoom (up to 18mm sensors) and the supplemental CentriTel® Focuser.  Finally, it is easily used for outside assignments or in the field, directly mounted on a DSLR or 35mm SLR.
