Polariscope

White Fluorescent Lamp

Cool diffuse 7 Watt 4,000 Kelvin neutral daylight lamp with the intensity of a traditional 35 Watt incandescent.

Optional Stoneholder

MAGNETIC-CLICK stoneholder system left or right position selectable.

Interference Figure Lens / Conoscope

Optional sphere lens, to swivel in / out. Height adjustable. Left or right placeable.

Wide Field Filters

Both filters of 50mm / 2" diameter. Analyzer filter rotatable 360° on the bracket.

360° Stone Support Disk

Free turnable glass disk of 50mm / 2" diameter.

Refractometer

SCHOTT / ZEISS optical glass

Large 5x12mm contact surface, made of precisely polished high-end special glass LaSF.

Filter 589nm
