• When the rod is pushed completely into head, 100% of the microscope image is directed to the binocular eyepiece for observation. 

• In the mid-position, adjusted until a click is heard, 100% of the image is directed to the trinocular port for photographs or video images. 

• In the fully extended position, 30% of the image is directed to the binocular eyepieces, and 70 % to the trinocular port.

A. To adapt a photographic camera, an adapter tube is required. (Fig. 3). This adapter tube includes a 2.5X photographic lens which measures the parfocality correctly between the images of the binocular and vertical ports. The adapter tube also requires a T mount adapted to fit the T threads of all reflex photographic camera brands on the market. 

1. To install the camera on the microscope, first remove the front lens of the camera and put the thread in its place. Then screw in the adapter tube to the thread of the camera. 

2. Loosen the knurled screw located on the side of the dual viewing head until the protective cap that covers the port can be removed (Fig.4). 

3. Insert the adapter tube with the camera mounted on the vertical port. If it does not connect easily, unscrew the knurled screw until the adapter tube drops into the port and is firmly in place. 

4. Tighten the knurled screw firmly to support the camera well in place. 

5. Place the sliding rod to mid, or extended position to allow the image to be directed to the camera. 

6. Operate the camera according to the manufacturers instructions.

B. To adapt a video camera, an adapter tube is required (Fig. 3). This adapter contains a 0,5X lens for video that measures the correct parfocality between binocular, and the vertical port images. The vertical port is responsible for the images appearing on the TV monitor. The adapter tube also includes a “C” knurled ring and a “CS” type ring to accommodate different types of video cameras. 

1. To install the camera on the microscope, screw the adapter tube on the video camera. 

2. Loosen the knurled screw located on the side of the dual viewing head until the protective cap that covers the port can be removed (Fig.4).
