Features

1.Kohler illumination

Koehler illumination is known as the perfect illumination system for microscopes, which provides perfect brightness and uniform field of view while making it possible to expand the functions of microscopes.

2.Strain-free optical components

Strain-free optical components make imaging more accurate. For polarizing microscope, not only is high imaging clarity essential, but stress-free optical components are also essential, ensuring that the observed birefringent phenomena come from the sample and not from the optical elements.

3.Center adjustable quintuple nosepiece

Quintuple nosepiece, center adjustable, allows each objective to be easily and quickly adjusted to the center of the optical path. The nosepiece can be equipped with 5 objectives with different magnifications, obtaining rich sample information.

4.Intermediate tube

Build-in Bertrand lens can switch very quickly from conoscopic and orthoscopic images. The polarizing set includes 0-360° rotatable analyzer.

5.Multiple types of compensators

BS-5095 provides various compensators that can enhance the signals of weak birefringent materials, making them easier to be seen. At the same time, the compensators can also be used for qualitative measurements, enabling the determination of multiple levels of delay.

6.High-precision revolving round stage

The large platform, convenient for rotation, can be adjusted to set the rotation center at a 45° angle. The double-layer mechanical moving stage can be easily installed on the rotary platform, making sample movement easier and more efficient.

7.Viewing head

Tilting Seidentopf trinocular viewing head (optional) can be operated in a more comfortable position. Minimize muscle tension and discomfort caused by long time work.

8.Rotary observation module

Up to 6 observation modules can be placed in the rotating disc structure, different observation method can be quickly switched.

9.ECO function

The transmitted light would be off automatically after 30 minutes from operators leave. It can save energy and extend the lamp life.

10.Display showing microscope status

The LCD screen at the front of BS-5095B and the touch screen at the front of BS-5095C can display the usage status of the microscope, including magnification, light intensity, sleep status and so on. It can remember the illumination brightness used for each objective and automatically adjust the light intensity when switching between different objectives, reducing visual fatigue and improving work efficiency.

11.Brightness memory function

It can remember the illumination brightness of using each objective and automatically adjust the light intensity to the corresponding brightness of each objective when different objectives are converted to each other, reducing visual fatigue and improving work efficiency.
