Introduction

Thank you for your purchase of a Motic microscope. Motic microscopes are precision instruments, subjected
to meticulous examination in order to reach you in perfect condition. Their design combines easy
management and optimum functioning with minimum maintenance.
The information contained in this manual is likely to go beyond what the average user needs to know to use
the microscope, however, it is provided to answer any queries that may arise.

Your new microscope combines high performance features, with an excellent degree of optical resolution
and clarity of image It incorporates a circular rotating stage with a 1º graduation, that permits the exact
positioning of the sample. Objectives located on a ball bearing nosepiece allowing movement in both
directions, a precision coarse and fine focusing system; a moveable Abbe condenser with a numerical
aperture of 1.25 N.A. and a built-in 12V/ 20W halogen variable light source.

These instructions should be read carefully before operating the microscope. They will permit you to use
your new microscope to its fullest capabilities. Terminology used to describe components and controls can
be found in the diagram on page 2.

These instructions are based on the assembly and use of the PM-2805 model with additional notes
applying specifically to the PM-1805 model.
Unpacking

All components of the microscope have been carefully packed to make sure they reach you in perfect
condition. We recommend that you do not discard any packing containers in case you need to return the
microscope or store it for long periods of time; or should it become necessary to transport it to a technical
service for any repair, or maintenance procedure.

The box should contain the following components, depending on the model:

• PM-1805: A microscope mounted with a monocular head, eyepiece, circular stage, 1,25 A.N.

condenser, three objectives, a polarizer integrated into the illuminator and an analyser. Also included
is a blue filter, a protective cover and two 2mm and 0.85mm hexagonal keys.

• PM-2805: A microscope with a monocular head with an analyser, a Bertrand lens and some
integrated plates λ and 1/4 λ, eyepiece, circular stage, 1,25 A.N. condenser, three objectives, a

polarizer integrated into the illuminator. Also included is a blue filter, a protective cover and two
2mm and 0.85mm hexagonal keys.

Remove and handle the microscope and all its components with extreme care.

Avoid touching the lenses of the optical elements and keep clear of contact with dust, water or other
contaminating agents, as they could stain, or damage the lens surface and affect the quality of the
image.

A. Place the microscope in a vertical position on a flat, clean and stable surface.

B. Extract the rest of the components from the box.

Description of components

1. Head (13). Monocular and 360º rotating so that another user can observe without the necessity of
moving the microscope.

2. Eyepiece (1). The group of lenses closest to the eye, they magnify the image formed by the
objectives. In monocular models, the eyepiece contains a pointer to signal any particular aspect of a
sample to another user.

3. Revolving nosepiece (4). Magnification can be changed by rotating the nosepiece. An indicator in the
optical path indicates the correct positioning of the objective.

4. Objectives (5). The group of lenses closest to the sample or microscopic slide. They form the first
image.

5. Stage (7). Surface where the slide is placed. The stage is circular and can be turned 360º , stage
clips are also provided.

6. Condenser (8). Optimises the illumination to obtain a high level of resolution and image contrast.

7. Focus knobs (17-18). Situated on both sides of the microscope arm, the bigger, coarse focus knob,
permits a first approximate focus, and the smaller, fine focus knob, permits a precise adjustment of
focus.

In the model PM-1805 The knobs are separate, and on the model PM-2805 they are coaxial.

8. Illumination (19-20). These models include 12V and 20W Halogen bulb, pre-centred and can be
regulated in intensity.

Assembly

All the steps described for the assembly of the microscope must be undertaken with extreme care ,
and without forcing the placement of the distinct parts and elements of the microscope.

A. Filter: This filter should be used if the illumination on the field of vision appears yellowed.

Place the blue filter in the filter holder (11) situated under the condenser (10), open the filter holder
by pulling out horizontally. Make sure that the filter is placed correctly, and close the filter holder.

B. Analyser: Only for the PM-1805. Connect the analyser to the eyepiece (1). In the PM-2805 the

analyser is already installed in the head.

Warning: Before connecting the microscope to a power source, ensure that the voltage coincides with that of
the microscope.
