L2020 Plan achromatic objectives with long working distance metallurgical microscope
L2020 reflected and transmitted metallurgical microscope is equipped with reflected and transmitted illuminator system, plan achromatic objectives with long working distance (no cover glass), wide field eyepieces and set polarizer device in trinocular. They can obtain clean image in the wide visual field, can be broadly applied in mine, colleges and scientific research department to observe internal configuration of material.
Features
▲ With plan achromatic objectives with long working distance (no cover glass) and wide-field eyepieces, can get clear pictures and wide view field.
▲ Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2μm.
▲ Utilize reflected &transmitted light mix illumination; you can descry the special effect in some object.
▲ 6V 20W Halogen lamp, adjustable control.
▲ Trinocular, can switch to observe normally or to observe the Polarize, can send 100% of light to the binocular eyepieces or to the top port.
