The Brunel Unilink is designed to work with most compact digital cameras that cannot
have their lenses removed. The Unilink incorporates a lens system that replaces the
eyepiece of the microscope. It also has a 37 mm male screw thread that can be used
to attach cameras that have lens screw threads or lens adapters with screw threads.
In addition it is tapped to take the screw thread of the Brunel Link arm - used for
the many cameras without lens screw threads.
The Unilink can attach to camera screw threads via step rings. If for example your
camera has a 46 mm screw thread then a 46 to 37 mm step ring is needed - and so on.
If like a lot of the cameras there is no lens screw thread then it can be attached
to the Unilink via its tripod bush. This is a screw thread usually in the base of
the camera that is used for attaching it to a tripod. The three elements of the Linkarm
allow a frame of stainless steel to hold the camera very firmly next to the lens
of the Unilink - it works with all cameras that have a tripod bush - irrespective
of its position in the camera.
The Unilink will fit into all monocular, binocular or trinocular standard compound
microscope eye tubes (23.8 mm internal diameter). The thickness of the eye tube wall
does not matter, the Unilink will fit all types. For binocular stereomicroscopes
we have eye tube inserts that reduce the internal diameter to suit the Unilink. Most
stereos are either 30 mm or 30.5mm in diameter (measure carefully please!). To check
