BH2 Accessories from the Empire of Dirt Workshop
Note: Because the actual components, which are made in black plastic, are difficult to photograph, the component images on this page are idealized computer renderings to illustrate the physical geometry of the various parts.
The STL files for these accessories are available for free, to allow anybody to print them for non-commercial purposes. If you don’t have access to a 3D printer, perhaps you have a niece/nephew or a grand child who can print these for you. If not, contact me and I can supply them for the prices listed below (with significant discounts available if you buy multiple items).
If you run across anybody selling these parts (other than myself), please contact me, as they are likely doing this illegally!

BH2 Filters from the Empire of Dirt Workshop
BH2-ND8 Neutral Density Filter – ND8
This filter allows a standard 45mm filter to be placed into the filter recess below the condenser (if desired) and then fits over this to introduce three exposure stops (i.e., ND 8) of light attenuation.
This filter is great for use with high-brightness LED illuminators, which can be uncomfortably bright for low-power observations. This filter comes with a custom 2-piece storage canister, which doubles as a dust cap when the filter is in place on the scope.
Price: $20
BH2-ND16 Neutral Density Filter – ND16
This is a high-quality neutral density filter made specifically for the Olympus BH2.
This filter allows a standard 45mm filter to be placed into the filter recess below the condenser (if desired) and then fits over this to introduce three exposure stops (i.e., ND 16) of light attenuation.
This filter is great for use with high-brightness LED illuminators, which can be uncomfortably bright for low-power observations. This filter comes with a custom 2-piece storage canister, which doubles as a dust cap when the filter is in place on the scope.
Price: $22
BH2-POL Custom Back Cover
This is a replacement cover for the back of the BH2 pillar arm, which is compatible with the BHS/BHSP/BHSU and BHT/BHTP/BHTU scopes. This replaces the existing cover on the scope, providing a handy storage slot for the centering keys used on the polarizing scopes. The centering keys fit into the carrier, which in-turn slides into slot in the top of the cover, safely storing the centering keys so that they do not get lost. The key carrier secures into the slot on the cover using four powerful neodymium magnets. There are two versions available. One is compatible with the early scopes built with metal back covers, and the other compatible with the later scopes made with plastic covers. Price: $35 / Each
BH2 3D-Printed Accessories from the Empire of Dirt Workshop
The STL files for the following parts may be freely download for personal, non-commercial purposes. If you don’t have access to a 3D printer, please contact me and I can provide them.
The BH2-DFR Darkfield/Rheinberg Kit
The BH2-DFR Darkfield/Rheinberg Accessory Kit from the Empire of Dirt Workshop adds Darkfield Illumination or Rheinberg illumination to the Olympus BH2.
COMPATIBILITY: The BH2-DFR is compatible with the BH2-CD and U-AC2 Abbe condensers, as well as the BH2-AAC aplanatic/achromatic condenser. The BH2-DFR provides darkfield or Rheinberg Illumination (with suitable Rheinberg filters) for 4x through 20x objectives (and likely low-NA 40x objectives, with careful setup).
The various components of this kit can be made on just about any 3D printer. If you don’t have access to a 3D printer, someone you know likely does. If not, please contact the Empire of Dirt Workshop.
Please don’t get overwhelmed when you look at the BH2-DFR PDF. There are a lot of parts in this kit, but to do basic darkfield on your BH2, you really only need two of those parts!
The BH2-DFR was designed to place a simple darkfield patch stop or Rheinberg filter up into the bottom bore of the condenser, very close to the aperture diaphragm within the condenser. Close proximity of the darkfield patch stop to the aperture diaphragm is a necessary condition to achieve acceptable darkfield.
Don’t fall for the misinformation out there. Attaching a patch stop to the bottom of your condenser will not work well for the BH2, since the aperture diaphragm is not physically close enough to the condenser mounting dovetail for this method to provide acceptable results.

The Empire of Dirt Workshop BH2-OBL Oblique Accessory Kit
The BH2-OBL accessory kit from the Empire of Dirt Workshop adds Oblique Illumination or Darkfield Illumination to the Olympus BH2.
COMPATIBILITY: The BH2-OBL is compatible with the BH2-CD and U-AC2 Abbe condensers, as well as the BH2-AAC aplanatic/achromatic condenser. The BH2-OBL adds simple Oblique Illumination or (limited) Darkfield Illumination to the Olympus BH2.
The various components of this kit can be made on just about any 3D printer. If you don’t have access to a 3D printer, someone you know likely does. If not, please contact the Empire of Dirt Workshop.
The BH2-OBL was designed to place a simple oblique stop (or darkfield patch stop) up into the bottom bore of the condenser, very close to the aperture diaphragm within the condenser. Close proximity of the oblique or darkfield patch stop to the aperture diaphragm is a necessary condition to achieve acceptable darkfield.
Don’t fall for the misinformation out there. Attaching an oblique stop to the bottom of your condenser will not work well for the BH2, since the aperture diaphragm is not physically close enough to the condenser mounting dovetail for this method to provide acceptable results.
