A 1.3 CF Lens and Protective Window
The optional CF lens allows the measurement of very small objects and can be used in combination with the
CT-SF02, CT-SF15, CT-SF22, CTM-1, CTM-2, CTM-3 models. The minimum spot size depends on the used
sensor. The distance is always measured from the front edge of the CF lens holder or laminar air purge collar.
The installation on the sensor will be done by turning the CF lens [TM-CF-CT] until end stop. To combine it
with the massive housing please use the version with external thread M12x1 [TM-CFAG-CT].

If the CF lens is used, the transmission

CTM-1 0.80
CTM-2: 0.87
