This is description of this part:
Revolving nosepiece for the Olympus CX31 microscope.
In Olympus CX31 microscopes the nosepiece is attached to the upper, exchangeable arm. The complete arm together with the nosepiece carries the manufacturer's catalogue number AW019700 and the name "CX31 arm ass'y". I am not offering the complete microscope arm here. What I show and offer here is only the nosepiece itself (the rotating turret disc), together with the click-stop latch spring. The part offered here should be treated as a service part used to repair the nosepiece when it gets damaged.
On the arm from which this particular nosepiece was removed, the manufacturer placed the casting number AD7858 - but I do not know whether this is the permanent number of this component or merely the number of the mould in one particular factory. Based on my experience with other, similarly marked Olympus parts, I lean towards it being the permanent numbering of this component.
The set offered here consists of:
- central screw together with bearing balls - it forms the rotation axis of the nosepiece and fastens it to the arm casting
- silver-plated brass turret disc with four objective seats with RMS thread
- set of bearing balls around the turret disc
- thin brass sliding washer
- click-stop latch spring with ball - for stopping the nosepiece in a given position while turning it
- rubber grip ring around the nosepiece that makes it easier to hold
Important: this nosepiece does not fit the polarizing version of the Olympus CX31 microscope, that is the CX31-P. The nosepiece in Olympus CX31-P microscopes allows the objectives to be centred, and the one shown here does not have that function.
What is this part needed for?
- as a service part, when a damaged revolving nosepiece needs to be replaced
