The optics

Stereo Zoom microscopes provide the ability to see fine details in three dimensions. The optical excellence permits better, faster, more reliable identification, analyses and measurements. It is designed for years of rugged use and it produces a three-dimensional image that mimics the depth perception and colour sensitivity capabilities of the human eye. The long working distance and narrow objective body design allow easy manipulation of the inspected diamond. With the D-scope one of the four different optics are offered (tri-optics available on request) :

When ordering, one of the above optics must be chosen. If you have an old type of microscope, but the optics are still in good shape, we can even deliver you the D-scope without optics. We only have to provide you with the right optics-holder.

The Lights

The D-scope is equipped with a sophisticated illumination system. The foot of the microscope contains a built-in lighting unit, which gives you the unique darkfield lighting. Darkfield, which is perfect to examine even the smallest inclusions. The overhead daylight illumination is very useful to study clarity, like structure phenomena, and even colour. The conditions of an examination with a loupe 10x in daylight can be simulated. With the overhead fluorescence illumination it is possible to study the fluorescence of diamonds. Furthermore the lamp can be tilted forward and backward for an optimal positioning.

The gem manipulator

The gem manipulator consists of a small vacuum system, connected to a stage on a holder. The vacuum, created by a pump, is lead through a small tube to a suction pad. The diamond is firmly held by this suction pad, which makes it possible to move the stone in all directions without touching, avoiding dirt and dust. Because the suction pad holding the stone is so small, it can be studied from all sides without the view being obstructed. The pads come in different sizes, so that even very large diamonds and the most unusual fancies can easily be examined. The vacuum manipulator is easily manipulated with a special designed joystick.

Advantages

The new ergonomic and nice-looking design The combination of a conical and parabolic reflector guarantees an optimal, highly efficient dark-field lighting, perfect for examining even the smallest inclusions without blinding or confusing the user in any way The long working distance and narrow objective body design allow easy manipulation of the inspected diamond All manipulation in one hand.

Technical Specifications

The microscope is equipped with oculars for magnification 10x. The zoom factor is adjustable from 0.65x to 5x. The total magnification therefore ranges from 6,5x to 50x. Mounting an extra lens can boost it even more. A standard spare-part includes a special ocular for measuring dimensions and proportions – the HRD -graticule The overhead illumination unit uses a 4-watt daylight TL-tube and blacklight blue LW 350-400nm. The built-in lighting unit is suitable for low-voltage halogen lamps of 35 Watts The total unit is CE and UL approved, and can be delivered with the necessary documents.

The D-Scope set is packed in a practical carrying case, and is very easy to install even on a limited space. For shipment we use special plastic transport cases.

NEW

The diamond microscope "D-Scope" can be equipped with a special LED illumination system instead of the regular halogen or TL-light. The LED illumination gives you more, whiter and brighter light.
