FOCUSING THE TRISTAR

1. Set the binocular eyepieces to "0" and adjust them to the proper interpupillary distance.
2. Peering through the eyepieces, move the entire TriStar backwards or forwards to get a "rough"
focus on the target. (12" or 300mm from objective lens to target.)
3. Set the fine focus by rotating the fine focus adjust lever (the same lever as the tilt adjust) until
the rack is at the midpoint.
4. Focus at the highest magnification. Focusing at this magnification is extremely critical and
leads to perfect focusing for all other magnification levels. Thereafter, the physician only has
to switch to another magnification without the need to refocus the instrument. If the instrument
is repositioned, however, the procedure must be repeated.
5. To set the image of the target in each eye, turn the eyepieces themselves. (Notice that the
eyepieces are calibrated to help refocus the eyepiece setting next time.)
6. Focusing is complete.

ACCESSORIES

Your TriStar split beam colposcope is designed to provide the ultimate ease in colposcopic digital
photography. The complete system of photographic equipment for digital pictures has been
created to allow even the novice photographer to clearly document visual observations for patient
files.
No special techniques are required and there is no need to remove the camera when photography
is not intended. Camera focusing is achieved through the TriStar oculars.

Digital Camera Attachment

1. Remove camera lens cover. Attach the adaptor mounting ring to the camera by aligning the
red mark on the ring with the red dot on the camera lens mount. Then turn the ring until a click
is heard when the attachment is secured.
2. Remove the black cap on the digital camera photo adaptor by loosening the stainless steel set screw.
Place the end of the adaptor mounting ring into the photo adaptor and retighten the set screw.
3. Attach the digital camera photo adaptor to the colposcope accessory port. The camera may be
mounted on either the right or the left accessory port.
4. Remove the protective accessory port cap. Guide slots on the photo adaptor permit the
positioning of the camera. Align the slots in the photo adaptor with the guides on the adaptor
ring. Slide the adaptor ring over the photo adaptor and tighten gently in a counterclockwise
direction. DO NOT OVER TIGHTEN
5. The camera is now ready for use.

Digital Photography

Refer to instruction manual for digital camera.
Looking through the oculars, adjust the instrument for focus and composition. When the desired
image is obtained, press the shutter release button on the camera to make the exposure.

Teaching Tube

For teaching or co-observation the teaching tube provides a second party viewing head as an
optional accessory.
The teaching tube may be mounted on either the right or the left accessory port provided on the
beamsplitter. Remove the protective accessory port cap. Guide slots on the teaching tube allow
for positioning of the unit. Align the slots on the teaching tube with the guides on the adaptor ring.
Slide the adaptor ring over the teaching tube and tighten gently in a counterclockwise direction.
DO NOT OVER TIGHTEN.
