Choosing the Proper Infinity Instrument:
Camera/Sensor Formats

It may come as a surprise, but "all Infinity instruments are equal." By that, we mean that all Infinity instruments can provide the same image quality–only from different working distances and for different camera/sensor formats. For example, if the InfiniVar™ CFM-2/S is used at a working distance of c.30mm, it will provide 3.2x primary magnification. Model K2/S can attain 3.2x primary magnification at nearly 160mm—more than 5 times the InfiniVar's working distance. On the other hand, if extreme working distances are not required and you want a small, table-top instrument, InfiniVar CFM-2/S is a better choice.

The format (camera/sensor) size is also important to consider. For example, an InfiniProbe can be used at similar working distances to that of the InfiniVar CFM-2/S. However, if you need to image onto a 35mm or digital camera and very large-sensored video cameras, InfiniVar CFM-2/S would be the obvious choice. The important thing to remember is this: over the years, we have had much experience designing instruments for many diverse applications; many proved so useful that they were put into general production.
