The Motic® AE31 Elite inverted microscopes provide excellent optical quality and unmatched operational convenience. The Color Corrected Infinity Optical System (CCIS®) allows new accessories and functions to be incorporated into the AE30/31 inverted microscopes at any time. The CCIS® infinity design has succeeded in achieving longer working distances with higher Numerical Apertures (NA) representing a significant improvement in optical performance and versatility.
A complete range of eyepieces and objectives are available to configure the AE31 Elite for your application.
The design of the AE31 Elite series inverted microscopes has been optimised to integrate all functions enabling effective ergonomics and maximum expandability. The wide base provides strength and rigidity; furthermore the inverted "Y" support at the back on the base provides extra lateral stability. The size of the microscope is compact to minimize the footprint and conserve the limited desk space available in modern laboratories.
The ergonomic design of the AE31 Elite enables easy and stress‐free operation. The coaxial coarse/fine focusing knobs, controls for the stage and light intensity, are placed conveniently at your finger tips to minimize fatigue.
The 6V/30W halogen Koehler illumination system provides bright, even illumination at any magnification. The "only‐one‐in‐its‐class" centerable lamp is housed externally and has an externally operated control mechanism for all facets of illumination. A segmented illumination intensity indicator is ideally located for easy viewing.
An energy saving Auto‐Off feature turns the instrument off if not used for 15 minutes. New Light Memory function, based on encoded five position nosepiece, will recall the last light intensity setup when changing ot a respective objective. Once set, there is no need to adjust the illumination when changing magnification.
In order to maintain absolute parfocality, the Siedentopf eyepiece tubes will not change their length when interpupillary adjustments are made. The inclination of 45° for the binocular and trinocular tubes is chosen for comfort and posture management.
Trinocular version features professional light distribution slider for 100% binocular and 20/80% for binocular/photo. The trinocular heads are ideal for digital documentation and video projection.
The standard Wide field 10x eyepieces for the AE31 Elite with an enlarged field of view of 22mm provides enlarged viewing fields for faster scanning and easier viewing. Parfocal focus is provided by independent diopter adjustment on each eyepiece. Users wearing eyeglasses will find the eyepieces' high eye point design very comfortable to use. Various graticules for measuring and counting are available for these eyepieces.
Quintuple Revolving Nosepiece
The revolving left side facing nosepiece accepts five objectives. It runs on precision ball bearings and has internal positive click stops so that the image remains centered after each change in magnification. The internal components and the optics are sealed against fluid spills to ensure reliable and trouble‐free usage. This allows the operator to concentrate fully on imaging the specimen and not to worry about accidentally damaging the microscope.
The CCIS® objectives for inverted microscopes have long free working distances in comparison to normal objectives of the same magnification. The objectives are optically corrected to compensate for 1.1mm thick glass slides and provide easy routine operation. RMS thread.
Phase Contrast Microscopy
Phase contrast is the most popular optical contrast method for viewing the detailed structure of unstained or living specimens. The Phase Plan Achromat objectives, coupled with the easy‐to‐operate phase slider, provide outstanding contrast for the most demanding applications. For a quick and easy change of magnification, Ph1 annular ring is provided on the centerable phase slider.
The centerable condenser mount is height adjustable with rack and pinion and is dovetail mounted on the illuminating pillar with a solid clamp screw. The ELWD condenser with a numerical aperture of 0.30 and a working distance of 72mm is suitable for objectives of magnification from 4x ‐ 40x with an aperture diaphragm in the bright field Koehler illumination and for phase contrast.
The phase annular ring Ph1 for 10x, 20x and 40x and Ph0 for 4x are centered by Allen Hex keys on the centerable slider.
Mechanical Stage and accessories
The standard stage is a fixed stage plate: the stage can be widened on both sides with auxiliary stage plates. A hard coating protects the stage surface from abrasion and wear. The tempered glass stage insert allows for checking the objective being used without removing the specimen from the stage.
An optional attachable mechanical stage with Well plate holder with low positioned coaxial controls is available. The mechanical stage also accepts interchangeable specimen holders for Petri dishes and glass slides.
