BS-5064B
New designed BS-5064 improves the destressing imaging system, reflected illumination system and lamp house, resulting in higher polarization and more vivid image. Green manufacture in full operation based on HSF environmental policy. Based on ergonomic designs, the operation is more convenient and comfortable.

Intermediate device for professional conoscopic observation, with internal Bertrand lens with analyzer slot, λ & λ/4 & quartz wedge attachable.
The center of Bertrand lens is adjustable, with rotating switch, cyclic focusing, making it easier to observe interference image.
Pluggable analyzer, 360°rotatable, 2°increment, 6′precision.
Pluggable polarizer is removable for natural light observation and easy to be replaced.
Removable beam splitter is designed for ensuring that all imaging light can enter the observation tube during transmission observation, improving the image quality under interference and orthogonal polarization.

For polarizing observation, the vibrating axis of the polarizer and analyzer in microscope should be orthogonal. In another word, the east-west vibrating axis and the south-north axis should be in line with the vertical and horizontal scale line of reticle in the eyepiece. Therefore, it is necessary to have a bayonet for fixing the eyepiece with reticle.

New producing and assembling technology of the objectives effectively eliminate the stress effects in heat treatment, gluing, assembly and calibration process. The background of field of view is almost black in orthogonal state, and the entire set of objectives has basically completely eliminated stress. It is especially well done for reflected observation.
