Olympus OM Equipment for Close-up and Macro PhotographyEyepiece AdaptersIntroductionThe eyepiece adapters are designed to clamp on to the eyepiece tube of a microscope, and provide a dovetail fitting to which the Photomicro Adapter L can be clamped. A microscope photo eyepiece fits inside the eyepiece adapter.
Olympus OM Eyepiece Adapters PM-ADP, PM-ADF and PM-ADG-3 There are 3 series of adapters:
Eyepiece Adapter PM-ADFThis adapter is intended for use with the NFK photo eyepieces (for the Olympus LB series of objectives, 45 mm parfocal) and the FK photo eyepieces (for older objectives, 36.65 mm parfocal). The adapter clamps on to a vertical monocular tube with an outside diameter of 25 mm or slightly less, and has a narrow lip that sits on top of the tube. Some older microscopes that take standard eyepieces have thick-walled tubes with a larger outside diameter than 25 mm, and the PM-ADF adapter cannot be used with them.
Olympus OM Eyepiece Adapter PM-ADF The adapter is not marked “Olympus” or “PM-ADF”.
VersionsOnly one version is known. When it was first introduced, the PM-ADF was known as the “FK Adapter”. Instruction bookletReproduced with permission from the copyright owner, Olympus Optical Co., Ltd HOW TO USE THE PHOTOMICRO ADAPTERS L & H

Eyepiece Adapter PM-ADGThis adapter is intended for use with the Olympus G series 10×, 15× and 20× eyepieces, which are used with stereomicroscopes and fit a tube with an inner diameter of approximately 30 mm. The adapter clamps on to one of the inclined binocular tubes, provided that the external diameter is approximately 31.5 mm.
Olympus OM Eyepiece Adapter PM-ADG The adapter is in 2 parts, which screw together. For the G 10× eyepiece, the eyepiece is inserted in the bottom section, and the top section is screwed on top of it. For the G 15× and G 20× eyepieces, the top and bottom sections are screwed together, and the eyepiece is inserted into the top section. The adapter is not marked “Olympus” or “PM-ADG”.
VersionsOnly one version is known of the original two-section PM-ADG. This was replaced by the PM-ADG-3, which has an additional section that fits between the other two, and allows the GWH 10× high-eyepoint eyepiece to be used. Another version, the PM6-ADG, was for use with the PM-6-8 35 mm photomicrography camera instead of the Photomicro Adapter L.

Eyepiece Adapter PM-ADG-3This adapter is intended for use with the Olympus G series 10×, 15× and 20× eyepieces and with the GWH 10× high-eyepoint eyepiece, all of which are used with stereomicroscopes and fit a tube with an inner diameter of approximately 30 mm. The adapter clamps on to one of the inclined binocular tubes, provided that the external diameter is approximately 31.5 mm.
Olympus OM Eyepiece Adapter PM-ADG-3 The PM-ADG-3 cannot be used with recent Olympus stereomicroscopes such as the SZ 4045, because their eyepiece tubes have an outside diameter of 32.7 mm. The GSWH 10× super-wide high-eyepoint eyepiece cannot be used, because it is too big to fit inside the adapter. The adapter is in 3 parts, which screw together. The top and bottom sections are identical to those of the PM-ADG adapter. For the G 10× eyepiece, the middle section of the adapter is not used; the eyepiece is inserted in the bottom section, and the top section is screwed on top of it. For the G 15× and G 20× eyepieces, the middle section of the adapter is not used; the top and bottom sections are screwed together, and the eyepiece is inserted into the top section. For the GWH 10× high-eyepoint eyepiece, all three sections are used; the eyepiece is inserted into the bottom section, and the middle and top sections are screwed on top of it.
VersionsOnly one version of the PM-ADG-3 is known. It replaced the PM-ADG, which has only two sections. Instruction bookletReproduced with permission from the copyright owner, Olympus Optical Co., Ltd HOW TO USE THE PHOTOMICRO ADAPTERS L & H

Eyepiece Adapter PM-ADPThis adapter is intended for use with the older Olympus P eyepieces. The adapter clamps on to vertical monocular tubes with an outside diameter of 25 mm or slightly less. The adapter slides completely on to the tube. The eyepiece is then inserted into the tube as normal, the adapter is raised until its top just comes into contact with the protruding lip of the eyepiece, and is then clamped in place.
Olympus OM Eyepiece Adapter PM-ADP Some older microscopes that take standard eyepieces have thick-walled tubes with a larger outside diameter than 25 mm, and the PM-ADP adapter cannot be used with them. The adapter is not marked “Olympus” or “PM-ADP”.
VersionsOnly one version is known. When it was first introduced, the PM-ADP was known as the “P Adapter”. Instruction bookletReproduced with permission from the copyright owner, Olympus Optical Co., Ltd HOW TO USE THE PHOTOMICRO ADAPTERS L & H
