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.


SCHOTT / ZEISS optical glass

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

Filter 589nm

For monochromatic illumination with 589nm wavelength. Without green because of narrow 15nm bandwidth.

Contact liquid nD 1.79

New formula of reduced toxicity, no cristallization and high transparency.
