Advance Solitaire Microscope (S-508)

The advance solitaire microscope is redesigned for more comfortable use of the incredible analysis tool for all type of Diamonds and Gemstones. We are very glad to introduce the advance version of the solitaire microscope with new illumination technology and touchpad remote control. It produces an accurate 3D image to make it possible to details of clarity & analysis of facets of the diamond. The new improved LED-based illumination can be adjustable with its own criteria and you can also save your light settings in program memory with just one click you can recall the settings you saved. The programmable lights are available from 2700 K (Yellow) to 6500 K (Day White Light) with the sweeping feature on touch pad remote pad.

Illumination

The Solitaire Microscope base is equipped with an advanced programmable illumination system that consists of unique combinations of Yellow & Day White LED based dark-field lighting & pattern LED ring illumination with Overhead a defuse uniform daylight or long wave fluorescent lamp. Moreover, for fluorescence quality check additional Gooseneck spot UV-LED light available.

Dark field halogen illumination

Darkfield microscopy is a very simple yet effective technique to study the inside characteristics of the diamond. A set of mirrors converges the light from all sides into the centre of the stone. It works by illuminating the diamond with light that will not be collected by the objective lens, and thus will not form part of the image. This produces the classic appearance of a dark, almost black, background with bright objects on it and it’s well suited for uses for examination of Diamonds. New LED technology is designed for serving a long period without failure.

LED illumination

LED (Light Emitting Diode) segmental ring light for shadow-free ring illumination and oblique light segment illumination. Only LED gives more and a brighter white light to the diamond. The operator can choose LED illumination in pattern format which offers operator extended examination possibilities.

Overhead a daylight

Daylight Illumination offers the best lighting conditions to study clarity, finish grade and even colour. Ideal for the grader to see at a glance the impurities of the stone being examined in 10X loupe.

Stand & Control Unit

Tilting Movement

New lightweight modular & ergonomic designed allow users a stress-free work. Due to its well-designed base body and easily adjustable in height and inclination, an individual user can set it as per their own comfort. The stand is rugged in design and all-in-one device that's easy-to-use and able accompanied all it’s existing and future accessories into it. Moreover, it can be quick to pack up and reinstall wherever it's needed.

Diamond Holder

It’s vacuum based gem holder, consist suction pad, lead with tube and the vacuum pump which is an integrated design of the microscope. It allows users to hold and move diamond in all possible direction with out the view being obstructed. Moreover, conventional magnetic wire/plan type tweezer is also available

Control Panel

The new console is designed to control power & illuminations. It has many functions to obtain a perfect lighting direction and intensity. Once you adjust the desired lighting for your eye comfort then you can save it for future and with one click you can recall it. You can save up to 7 programmed light settings.

Optics

Stemi 508

Zeiss Germany make Stemi 508 is a compact, reliable and equipped with optics and mechanics designed for heavy workloads especially field of gemological applications, with the large 36 mm object field you always keep the overview of your sample. The 8:1 zoom then allows to bring details up to 50× magnification. You even have larger diamond? Add interchangeable optics and observe an area of up to 122 mm.

Stemi 508 offers better ergonomics than any other Greenough type stereo microscope in the world. The low viewing angle of 35° lets you keep a relaxed posture even after hours of work With Stemi 508 you can observe Diamond & GemStone with sharp in focus and free from distortion or colour fringes. Optic is available in binocular and trinocular format. With a trinocular type, the third lens hole can be connected to a digital camera,allowing you to make pictures of your stones.
