CF-Lens and Protective window

The optional CF lens allows the measurement of very small objects and can be used
in combination with all LT, 1M, 2M, 3M and 4M models. The minimum spot size
depends on the used sensing head. The distance is always measured from the front
edge of the CF lens holder or laminar air purge collar..
The installation on the sensing head will be done by turning the CF lens until end
stop. To combine it with the massive housing please use the version with external
thread M12x1.
