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 and Format Matching

(Stand and camera not included)

An Insert is included with each InfiniVar CFM-2/S which accepts two supplied Cap Lenses:  Standard (STL) and Compressor (CTL). Both Cap Lenses screw onto the top of the Insert Lens. 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.

By using either the Cap Lenses—, 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.

DSLR and 35mm Format Capability (0-15x)

Simply by adding the IVR Tube (an optical component) and removing one of the supplied T24 tubes from the InfiniVar CFM-2/S configuration, sensors up to 24x36mm (the 35mm format) can be used. The magnification then ranges from 0-15x. In doing this, the length of the InfiniVar with the IVR Tube is less than 6mm longer than its standard configuration!

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.
