Olympus AX70 / AX80 AX-RFS microscope EPI fluorescence field diaphragm | reflected light iris diaphragm

The name of this microscope part.

Olympus AX70 / AX80 AX-RFS microscope EPI fluorescence field diaphragm | reflected light iris diaphragm

Description of this part for the microscope.

Olympus AX-RFS is a complete iris diaphragm module acting as a field diaphragm for the fluorescence EPI illuminator in Olympus Provis AX70 / AX80 microscopes. ...



Basic information:
Manufacturer: Olympus
Part number in the manufacturer catalogue: AX-RFS
Type of microscope element: field diaphragm with complete mechanical control mechanism
Compatibility: Olympus Provis AX70 and AX80 microscopes
Information: RFS = Reflected Fluorescence System

The modular construction of Olympus AX microscopes allows easy removal and installation of entire microscope elements, but this is often the reason why microscopes appearing on the secondary market are missing some modules.

This is a relatively complex module containing, apart from the diaphragm itself, knobs, control wheels, rods and mechanical gear transmissions. With improper handling or maintenance - and especially with lack of maintenance - this module may become damaged. The most common failures are:
- bending or breaking of the diaphragm blades
- unscrewing and loss of the diaphragm centering screws
- breaking of the knob used to open / close the diaphragm
- breaking of parts of the rotary motion transmission mechanism

Olympus BX40 microscope field diaphragm | repair spare part

The name of this microscope part.

Olympus BX40 microscope field diaphragm | repair spare part

Description of this part for the microscope.

Service part (repair element) for Olympus BX microscopes. This is a field diaphragm (iris diaphragm) together with the ring used to adjust the diaphragm opening. ...

Both elements (the diaphragm and the control ring) have gears which engage with each other after assembly and work together: rotating the control ring closes or opens the diaphragm blades

This is a part removed from the stand of an Olympus BX40 microscope. It has been tested and cleaned - and is suitable for use as a service element for repairing a damaged microscope. Many smaller Olympus service elements do not have their own catalog numbers or commercial names, therefore in the last photos in the gallery I indicate with an arrow exactly which element is being offered and where it is located inside the microscope. In this description some names used are descriptive rather than official technical commercial names.

Olympus BX series microscopes use identical assemblies in many different models, therefore there is a high probability that this element - although removed from a BX40 model - is also compatible with other BX series models (for example BX41, BX43, BX50, BX51 etc.). However, before deciding to install such an element in an Olympus BX microscope, it is advisable to first carefully compare shapes and dimensions or ask appropriate questions on forums and in Olympus BX microscope user groups.
