Summary of Contents for Motic BA310Met
- Page 2 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.
- Page 3 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.

IV. MICROSCOPY 1. Illumination brightness adjustment Turn the brightness adjustment knob fully counterclockwise to the low brightness position. Set the power switch to “I” (ON). The green line control lamp in the switch must light up. The halogen lamp 12V/50 W in the Epi illuminator must light up. ... -
Page 16: Coarse Focus Torque Adjustment
3. Coarse focus torque adjustment To increase the torque, turn the torque adjustment ring (Fig.7) located behind the left-hand coarse focus knob in the direction indicated by the arrow. To reduce the torque, turn the ring in the direction opposite to that indicated by the arrow. (Fig.7) 4. -
Page 17: Beam Splitter Lever
5. Beam splitter lever The beam splitter lever of the trinocular eyepiece tube can be used to select the amount of light distributed between the trinocular eyepiece tube and the vertical phototube. When the lever is pushed in until it reaches the limit, 100% of the light enters the observation tube. When the lever is pulled out to the limit, the ratio of light entering the observation tube and phototube will be 20:80. -

(Fig.12) (Fig.13.a) (Fig.13.b) 10. Aperture diaphragm of Epi-illuminator using The condenser aperture diaphragm is provided for adjusting the numerical aperture (N.A.) of the illuminating system of the microscope, it decides the resolution of the image, contrast, depth of focus and brightness. ... -
Page 20: Centering The Condenser For Ba310Met-T
Adjust and centre the field diaphragm so that it is just outside the field of view for each magnification change. 12. Use of aperture diaphragm for BA310Met-T The condenser aperture diaphragm is provided for adjusting the numerical aperture (N.A.) of the illuminating system of the microscope, it decides the resolution of the image, contrast, depth of focus and brightness. -
Page 21: Use Of Field Diaphragm For Ba310Met-T
13. Use of field diaphragm for BA310Met-T The field diaphragm determines the illuminated area on the specimen. For normal observation, the diaphragm is set slightly larger than the field of view. If the illuminated area is set much larger than the field of view extraneous light will enter the field of view. -
Page 22: Photomicrographic Procedure
V. PHOTOMICROGRAPHIC PROCEDURE To ensure vibration free operation, set the microscope on a sturdy vibration free table or a bench with a vibration proof device. Pull the optical path selection lever of the trinocular eyepiece tube all of the way out to the limit, the ratio of light entering the observation tube and phototube will be 20:80. -
