InfiniVar™ CFM-2/S

Continuously-Focusable Microscope

The World's Finest
Video Microscope.

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.

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

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.
