SORTOSCOPE® „COMBINATION FOR SORTING DIAMONDS OF ALL SMALL SIZES“ is the well-establishedand widest-spread SORTOSCOPE® model.

Since production was started appr. 15 years ago it was improved in many ways: NOSSIGEM LAB believesthat now is the appropriate moment to thank all SORTOSCOPE® users of the diamond business for themany helpful suggestions for improvement. Without that support the SORTOSCOPE® would have neverreached the sophisticated perfection of today.

With the SORTOSCOPE® high-quality diamond parcels are sorted for clarity and make in half the time aswith the common 10x loupe / tweezers method. The reliability is better.

Many companies handle small high-grade colored gemstones in the same way.

Even persons unconnected to the diamond business learn sorting using the SORTOSCOPE® within a fewweeks.

This SORTOSCOPE® model pays off in the shortest while.

SORTOSCOPE® „ZUSAMMSTELLUNG ZUM SORTIEREN VON DIAMANTEN ALLER KLEINEN GRÖSSEN“ istdas bewährte und das am meisten verbreitete SORTOSCOPE® Modell.

Seit Beginn der Produktion vor ca. 15 Jahren wurde es vielfältig verbessert: An dieser Stelle möchteNOSSIGEM LAB allen SORTOSCOPE® Benutzern aus dem Diamantbereich für die vielen Verbesserungs-vorschläge danken. Ohne diese professionelle Hilfestellung hätte das SORTOSCOPE® nicht die jetzigeausgereifte Perfektion erreicht.

Mit dem SORTOSCOPE® werden hochwertige Diamantqualitäten verfahrensbedingt etwa doppelt soschnell nach Reinheit und „make“ sortiert wie mit der 10x Lupe. Das Ergebnis ist sicherer und genauer.

Kleine hochwertige Farbsteine werden von vielen Firmen in gleicher Weise sortiert.

Auch fachfremde Personen lernen das Sortieren mit dem SORTOSCOPE® üblicherweise in wenigenWochen.

Dieses SORTOSCOPE® Modell macht sich in kürzester Zeit bezahlt.

The SORTOSCOPE® HIGH VISION model is the excellent result of many years research and practical testing.

The REFLECT-O-LUX darkfield illumination techniques designed by NOSSIGEM LAB, the acrylic rail method forsorting lots introduced by NOSSIGEM LAB, special NOSSIGEM illumination techniques using the advantages ofpartly polarized light – all this results in a wide spectrum of applications achieved by no other producer*.

The wide field of view – appr. 30 % more than in many comparable microscope optics – makes every kind ofhandling easier and more comfortable and is essential for sorting jobs lasting hours.

With the new SORTOSCOPE® HIGH VISION one of the world finest gemmological all-purpose microscope isnow available.

Das SORTOSCOPE® Modell HIGH VISION ist das herausragende Ergebnis jahrelanger intensiver Forschungund praktischer Erprobung.

Die von NOSSIGEM LAB entwickelten neuartigen REFLECT-O-LUX Dunkelfeld Beleuchtungstechniken,die von NOSSIGEM LAB eingeführte Schlittenmethode zum Sortieren von Steinpartien,spezielle NOSSIGEM LAB Ausleuchtungsmethoden unter Ausnutzung der Vorteile von teilpolarisiertem Lichtergeben ein von keinem anderen Hersteller erreichtes breites Anwendungsspektrum**.

Das grosse Blickfeld – mehr als 30 % grösser als bei vielen vergleichbaren Mikroskopoptiken –macht jegliches Hantieren einfacher und komfortabler und ist für viele Stunden dauernde Sortierarbeitenzwingend notwendig.

Mit dem neuen SORTOSCOPE® HIGH VISION steht nun eines der weltbesten edelsteinkundlichenUniversalmikroskope zur Verfügung.

SORTOSCOPE® RRH COMPACT is the next improved „budget“-SORTOSCOPEwith integrated illumination and modified handling.

Some of our major customers prefer this handling:

German Patent DE 37 38 041, US Patent No. 4906 083. SORTOSCOPE® is the registered trademark of NOSSIGEM LAB

May 2005

The SORTOSCOPE® RRH COMPACT is equipped with 1 SC-P-350 sorting bar 150 mm x56 mm, 11 mm high – instead of SC-P-300 SORTOSCOPE sliding rails 300 mm long.The 3 wider and higher grooves allow a much greater diamond filling capacity.

The SORTOSCOPE® RRH COMPACT comes with zoom microscope optics. Magnification6,5x – 45x infinitely variable (zoom ratio 1:7). Field of view at 10x 20 mm (WF oculars).

The SORTOSCOPE® RRH COMPACT is the first SORTOSCOPE that allows to mixtransmitted daylight illumination as usual with our special toplight in order to seeextra facets and polishing defects better than with other SORTOSCOPE models.
