Motic BA310Met User manual

We are constantly endeavouring to improve our instruments and to adapt them to the requirements of

modern research techniques and testing methods. This involves modification to the mechanical

structure and optical design of our instruments.

Therefore, all descriptions and illustrations in this instruction manual, including all specifications are

subject to change without notice.

INFINITY OPTICAL SYSTEM

An optical configuration (in which the specimen is located at the front focal plane of the objective)

gathers light transmitted through or reflected from the central portion of the specimen and produces a

parallel bundle of rays projected along the optical axis of the microscope toward the tube lens.

A portion of the light reaching the objective originates from the periphery of the specimen, and enters

the optical system at oblique angles, moving forward diagonally but still in parallel bundles toward the

tube lens. All of the light gathered by the tube lens is then focused at the intermediate image plane, and

subsequently enlarged by the eyepiece.

The real merit of the infinity based system lies in its ability to accommodate modular accessories in the

optical path and produce a flexible design.

I. DESCRIPTION

1. Application:

The Motic BA310Met and BA310Met-T are suitable for use in all areas of research and industry

observing opaque material, e.g. in

a. Metallography

b. Mineralogy

c. Mechanical engineering

d. Electronics

Except bright field observation, BA310Met and BA310Met-T are also used for polarized light

observation. BA310Met and BA310Met-T can be installed with digital camera, video camera for

photomicrography.

II. SETTING UP THE INSTRUMENT

Avoid placing the instrument in locations exposed to direct sunlight, dust, vibration, high

temperature, high humidity and where it is difficult to unplug the power supply cord.

1. Operating environment

Indoor use

Altitude: Max 2000 meters

Ambient temperature: 5°C to 40°C

Maximum relative humidity: 75% for temperature up to 31°C decreasing linearly to 50% relative

humidity at 40°C

Supply voltage fluctuations: Not to exceed ±10% of the normal voltage.

Pollution degree: 2 (in according with IEC60664)

Installation / Overvoltage category: 2 (in according with IEC60664)

Air pressure of 75kPa to 106kPa

No hoar frost, dew, percolating water, rain

III. ASSEMBLING THE MICROSCOPE

1. Input voltage

The automatic voltage selection works with a broad range of settings. However, always use a

power cord that is rated for the voltage used in your area and that has been approved to meet local

safety standards. Using the wrong power cord could cause fire or equipment damage.

In case of using the extension cord, use only a power supply cord with a protective earth (PE) wire.

In order to prevent electric shock, always turn the power switch on the power supply off before

connecting the power cord.
