Cognep Grading Microscope with CORRA SZ81 (6X - 52X Zoom)

The Cognep SZ81 Diamond Grading Microscope is designed for professionals who demand unmatched clarity and precision in diamond grading, polishing and analysis. Built with advanced optical technology and superior illumination systems, it ensures accurate inspection of cut, colour and inclusions - revealing every detail with brilliance.

Illumination System

A halogen lamp with reflector or 36 high-intensity LEDs provides sharp, focused lighting for detailed examination. The illumination system enhances the diamond's surface features, making it ideal for evaluating colour, cut and internal inclusions with utmost accuracy.

Darkfield Illumination

Specifically engineered to analyse the internal characteristics of diamonds. A precisely aligned mirror system directs light from all directions to the stone's centre, making even the smallest inclusions visible with exceptional contrast.

Overhead LED Illumination

Advanced LED lighting produces bright, white light - significantly superior to standard halogen or TL illumination - for consistent and accurate evaluation of clarity, cut grade and colour.

Manipulation System

A vacuum-based holding mechanism secures the diamond on a precision needle, allowing smooth rotation and movement with maximum flexibility and minimal obstruction.
