Description
Bright Field Observation
New infinite EPLAN/infinite PLAN achromatic objective supply the sharp image after adjusting Iris diaphragm. You can get high resolution and contrast ratio image at low or high magnification. 1W Single LED illuminator supplies bright background.
High-powered single LED cold light illuminator
It maintains constant color temperature and closes to sun light. It can apply bright white back-ground. The illuminator supplies stable brightness and temperature difference never occurred even long time worked. Comparing with halogen lamp, LED has lower power dissipation.Brightness is adjustable freely by the rotatable key at lower left side.
Eyepiece Tube
Seidentopf Binocular Head, Inclined at 30°, Interpupillary distance is adjustable from 55mm to 75mm. The right eyepiece tube is ±5 diopter adjustable.
Stage and Focusing
Double Layers Mechanical Stage 132X142mm/75x40mm
Coaxial Coarse and Fine Adjustment, Fine Division 0.004mm, Coarse Stroke 32.7mm per Rotation, Fine Stroke 0.4mm per Rotation, Moving Range 24mm
Objectives & Condenser
With quadruple nosepiece, it is equipped with Infinite Semi-Plan/Plan Achromatic Objectives：4X，10X，40X(S)，100X(S, Oil), NA 1.25 Abbe Condenser with Iris Diaphragm is able to acquire light brighter.
