The Olympus Duo Observation Attachment, Model DO, is a specialized accessory designed to enhance the functionality of Olympus microscopes, specifically models FHA, EHA, and E, by enabling dual observation. This attachment allows two observers to view a specimen simultaneously, making it an invaluable tool for teaching, collaborative research, and consultation in various scientific and educational settings.

Function Description

The primary function of the Olympus Duo Observation Attachment is to split the optical path from a single microscope, allowing two individuals to observe the same specimen at the same time. This is achieved through a main body unit that mounts onto the microscope in place of the standard viewing head, and two binocular heads that attach to the main body. The attachment also incorporates a pointer system, which allows one observer to highlight specific areas of interest within the field of view for the other observer, facilitating guided observation and discussion. A transformer is included to power the pointer's illumination. The system is designed to maintain a mechanical tube length of 160mm, ensuring compatibility with standard microscope optics.

Usage Features

Assembly and Setup:

The assembly process for the Duo Observation Attachment is straightforward. First, the existing viewing head of the Olympus microscope is removed. The main body of the Model DO attachment is then placed onto the microscope, secured with a mounting ring. Care must be taken during this step to avoid damaging the long, slim tube underneath the main body. The main body can be rotated 360 degrees and fastened in a preferred direction using a clamp knob. Next, the two binocular heads are attached to the sides of the main body, ensuring they are fastened tightly with their respective clamp knobs when the eyepiece tubes are in the uppermost position. It is crucial to ensure that the correct binocular heads are attached to avoid cutting off the marginal part of the view field. Eyepieces are then inserted into the sleeves of the binocular heads. Finally, the primary power cord of the transformer is connected to an AC outlet (compatible with 100V, 110V, 220V, or 240V), and the secondary cord from the projector tube on the main body is connected to the transformer.

Observation Adjustment:

Once assembled, the attachment requires adjustment for optimal viewing by both the principal observer and the sub-observer.

Principal Observer Adjustments:
1. The principal observer looks into their eyepiece and brings the specimen into focus using the coarse and fine adjustment handles of the microscope.
2. The interpupillary distance between the eyepieces is adjusted to match the observer's eyes.
3. The dioptric adjustment rings are turned in accordance with the interpupillary distance scale. This action adjusts the mechanical tube length to 160mm.
4. The focusing procedure is repeated with the coarse and fine adjustment knob of the microscope. If there is a dioptric difference between the observer's eyes, one dioptric adjustment ring is set to the interpupillary scale, and the other dioptric ring is focused directly on the specimen through the eyepiece.
Sub-Observer Adjustments:
1. The sub-observer adjusts the interpupillary distance to their eyes.
2. The scale of their dioptric adjustment ring is fitted to that of the interpupillary distance, maintaining the 160mm mechanical tube length.
3. If the sub-observer has a dioptric difference, they follow the same procedure as the principal observer (step 4). If this still doesn't fit their diopter, they can freely turn their dioptric adjustment ring to achieve a comfortable focus.

Pointer Usage:

The integrated pointer system is a key feature for collaborative observation.

The transformer is switched on.
The filter lever on the main body allows selection of the pointer's color (green or orange) to contrast with the specimen. When the lever is set to '0', the pointer color is orange; when set to 'G', it is green.
The intensity of the pointer is adjusted using the voltage knob on the transformer.
The pointer knob on the main body is used to guide the pointer to any particular target in the field of view. Rotating the knob on its axis moves the pointer up and down, while sliding the knob along its slit moves the pointer left and right.

Observation Magnification:

The total observation magnification is calculated as: Objective magnification × Eyepiece magnification × 1.25. The 1.25 factor is inherent to the optical design of the Duo Observation Attachment.

Maintenance Features

While the manual primarily focuses on assembly and usage, some aspects imply maintenance considerations:

Lamp Replacement: The standard set includes two spare 6V 5W GE lamps, indicating that the projector lamp for the pointer is a user-replaceable component. This allows for continued functionality of the pointer system.
Eyepiece Sleeve Caps: The inclusion of four eyepiece sleeve caps in the standard set suggests a recommendation for protecting the eyepiece sleeves when not in use or during storage. This helps prevent dust and debris from entering the optical path and protects the internal components.
Care during Assembly: The instruction to "Take care not to give any damage to the long, slim tube underneath the main body" during assembly highlights the importance of careful handling to prevent damage to delicate optical or mechanical components, which would be a form of preventative maintenance.
Cleaning: Although not explicitly detailed, the nature of optical instruments implies that regular cleaning of external surfaces and eyepieces with appropriate materials would be necessary to maintain clear viewing and extend the life of the device. The protection offered by eyepiece caps contributes to reducing the frequency of internal optical cleaning.
Electrical Connections: The instructions for connecting the primary and secondary cords, and the inclusion of a transformer, imply that proper electrical connections and handling of the transformer are part of routine care to ensure safe and reliable operation.

The Olympus Duo Observation Attachment, Model DO, is a robust and thoughtfully designed accessory that significantly enhances the utility of compatible Olympus microscopes by facilitating shared viewing and guided instruction, making it an indispensable tool for collaborative microscopy.
