The SLS Lab Basics Varizoom microscopes are modular microscopes and are not supplied with a trinocular (camera) port. To enable a camera to be mounted on a Varizoom microscope you must purchase a trinocular beam splitter and C-mount. The beam splitter fits between the zooming body and binocular head, raising the eyepieces by approximately 50mm. A C-mount is also required and is included free of charge in this offer package. Please note that the field of view captured by your camera will be narrower than the field of view seen through the eyepieces.
