ARM-B Advanced Biological Research Microscope

A Stable and highly versatile platform for advanced biological microscopy imaging.

Transmitted Light Biological Photo Microscope with Super-Widefield and Ultra-Widefield High Resolution PlanApochromatic objectives,
Choice of 5, 6 or 7-position Revolving Nosepiece to accommodate the wide range of available objectives.
Brightfield LED illumination and Manually operated Mechanical stage with convenient low level coaxial axis controls.
Choice of fixed angle or tilting eyepiece tubes combined with a vertical camera port.
Brightfield, Phase Contrast and DIC Optics to facilitate clear imaging of stained and unstained samples.

Intensity Control

Variable Intensity Rotating Illumination Control with LED intensity indicator and pre-set control for reproducing levels.
Built-in filters LBD, ND6 & ND25

Mechanical Stage

Double layer design 187x 168mm, movement area 80 x55mm.
Low-positioned concentric X-Y movement controls with vernier 0.1mm scale. and tension adjustment.

Condenser Centering

Dual adjustable controls to ensure alignment of the condenser with the main optical path to provide even illumination across the field of view.

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

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)

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

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.
