Article on horizontal microscopy

This article describes how to reduce the reflections from a gemstone by using horizontal microscopy.

"How to reduce the surface reflections from a gemstone."

Illumination

Light source is a high intensity 12 Volt / 20 Watt halogen coldlight reflector lamp for powerful illumination. Iris diaphragm for adjusting light intensity and focusing.

Swinging/rotating illuminator

The character of light varies from transmission to incandescence by rotating the illuminator around the specimen.

Dimmable light

Turning knob for electronic dimming the illuminator light source.

Magnetic-ClickŪ stone holder

Smart stoneholder for comfortable rotation and positioning of specimen. Mounted on magnetic ball socket on the vertical post.

Stage Mounting

Stage alternatively mountable on base for either left- or right-hand use.

Immersion cells

Two immersion cells of 40mm size included. Magnetically fixed on stage.

Immersion liquids

Immersion liquids of nD 1.57 and nD 1.66, each 100ml included. Liquid with nD 1.74 optional.

Polarisation

U-type polarizer, both filters rotatable, with magnetic fixing on the stage.

ZEISS or LEICA optics
