Field Iris Diaphragm

  • Rotating Field Iris Diaphragm to control illuminated area, ensure condenser focus and avoid excess glare in the image.

Coaxial Focus Control

  • Dual-sided coaxial coarse and fine focus controls to suit individual preferences

  • Adjustable Upper limit control to protect slides from touching objectives

  • Focus Tension Control to suit individual preferences

  • 25mm focus travel with fine focus precision 0.001 mm

Widefield & Super Widefield Eyepieces

  • 10x Widefield High Eye Point, Plan Eyepieces with -5/+5 Diopter Correction Adjustment, Field Number 25, with indexing point.

  • 10x Super Widefield High Eye Point Plan Eyepieces with -8/+5 Diopter Correction Adjustment, Field Number 26.5, providing a 12.5% increase in the field of view, with indexing point.

  • Reticule Eyepieces for Measurement and Photo Alignment

  • Soft rubber cups to aid spectacle & non-spectacle wearers. help to reduce the effect of ambient light.

  • Locating index/pin to prevent eyepiece rotation

ARM-B Nosepieces for 5/6/7 objectives

Trinocular Head

  • Trinocular Head Slider directs the image to the eyepieces for visual examination or to the vertical port for recording. The slider can split the functions between both directions.

  • Three different heads are available; two with a fixed angle eyepiece tube and the other with a variable angle, providing comfortable viewing for a single user or a number of users. The fixed angle heads provide an erect or reverse image.

  • The eyepieces have a centre pivoting, inter-pupillary adjustment of 50-76mm and tube-length correction adjustment.

  • The vertical port has a circular fitting to attach camera couplings.

  • Sliding Prism provides a split between eyepiece and camera port. (see specification below)

ARM-B Wide Field Eyepieces

Precision Revolving Nosepiece

  • Conveniently accommodate 5, 6 or 7 objectives using the interchangeable revolving nosepiece assemblies.

  • Each individual nosepiece is mounted on the microscope using a dovetail fitting which locates objectives both par-centrally and par-focally..

  • The objective thread size complies with the DIN / RMS standard. 

  • The nosepiece has a slot to facilitate the insertion of a filter/DIC prism.

Infinity Plan-Apochromatic Objectives

  • Flat-field, High Aperture and Colour Correction objectives match the 10x eyepieces and C-mount couplers to provide true colour and high definition images of samples.

  • Objectives are designed for transmitted light and a cover-slip thickness of 0.17mm

  • Magnifications

ARM-B Brightfield Flip-top Condenser
ARM-B Universal Turret Condenser

Versatile Condenser & Illumination

  • Focussing Substage accepts Simple bright-field Abbe-type condenser with 'flip-out' top lens (NA 0.2-0.9)

  • Universal condenser with turret for bright-field, phase contrast or DIC optics. NA 0.9 (dry) ~ 1.4 (oil)

  • Both condensers have adjustable aperture iris diaphragm to control depth of focus and contrast.

Universal Condenser for Optimum Image Control

​

  • Universal condenser has a rotating turret with 7-positions and a 'flip-out' top lens to provide low and high magnification bright-field, phase contrast and DIC [Differential Interference Contrast] imaging.

  • An Aperture iris diaphragm is located on the underside of the condenser to control the image contrast and depth of focus.

  • DIC prisms, Dark-field and Phase Contrast annuli are inserted in the rotating turret.

  • Sub-stage Polarising filter is incorporated in the condenser and the analyser +adjustable DIC prism is inserted in the nosepiece slot above the objectives.
