Nikon Metaphot/Fluophot Fine Focus Shaft

Direct Metal Replacement for the now unavailable Nikon Metaphot and Nikon Fluophot Fine Focus Shaft.  Aproximately 7.25 inches long as seen in the photo next to an original.

According to Nikon Parts Department, the much loved Metaphot fine focus shafts are no longer available.   Originally the gears on the fine focus shaft were made of black plastic molded onto a metal shaft and were so thin that they were known to split and are the main repair issue with these otherwise great microscopes.  

We now carry a metal version of this vulnerable gear already installed on a matching shaft.  This is an exact replacement part for the original Metaphot.  

Some are curious if other gears in the focus system will break because of the strength of this metal gear, but because of the design of the gear system, no damage can occur.  Even when the fine focus is turned at full stop, the coarse focus will reverse to take up the movement.   The only torque that is placed on the fine focus system would be old sticky grease, this is typically why the plastic gear would split.  There is no vibration associated with metal to metal contact because of the exact duplication of the gear to the original.
