VIEWING HEADS

Available with standard binocular heads or trinocular heads for photomicrography, 30° inclined eyetubes with adjustable diopter settings and interpupillary distance, 360° rotatable.

EYEPIECES

Paired DIN KHW10x, FN 20.

OBJECTIVE CHANGER

Smooth-operating, ball bearing mounted, quadruple nosepiece.

OBJECTIVES

S. Flat Achromats, SM Planachromats, Planachromats, or Phase Contrast.

STAGE

Attached mechanical stage: 120mm x 140mm surface with 75mm (X) by 40mm (Y) movement, graduated with vernier readings to 0.1 mm, drop-down right or left-handed controls.

Flat-top stage: 171mm x 140mm surface with 80mm (X) by 52mm (Y) movement, graduated with vernier readings to 0.1 mm, detachable specimen guide, drop-down right of left-handed controls.

CONDENSERS

Standard models have either an Achromatic NA 1.25 condenser with iris diaphragm and filter tray for brightfield work, simple NA 1.25 slider phase condenser, or an NA 1.25 Zernike phase condenser with filter tray and independently centerable annuli for phase contrast. Cardioid-type NA 1.25 darkfield condenser for high power (100x objective only) darkfield work is optional.

ILLUMINATOR

Built-in, 6V 30W, variable-intensity Koehler illumination for apertures up to 1.25.
