Introduction

Feature

1. Infinite Color Corrected Optical System provides sharp and comfortable images.
2. Wide-field high eye-point eyepieces and plan achromatic objectives make the effect of fluorescence observation more perfect.
3. Outstanding appearance design and ergonomics structure design, long time use without feeling tired.
4. With the design of security lock and safe limits, it is much more secure, stable and can be kept for long.
5. Various microscopic examinations can be fulfilled, such as brightfield, dark-field, phase contrast, fluorescence, simple polarizing and so on.
6. LED fluorescence excitation illumination, breaking through the traditional type, is more stable, low radiation and long working life. Special fluorescent filter for tuberculosis examination is available.
7. Rackless stage can avoid the potential hazard caused by moving rack.

8. Intelligent illumination system.
(1) With coded nosepiece, the microscope is able to automatically remember the light intensity of each objective which you are used to, it helps to improve the work efficiency and decrease the visual fatigue.
(2) LCD on the right side of the frame shows color temperature and light intensity, as well as the objective magnification you are using, it is helpful to make record of experiment condition.

(3) Color temperature can be adjusted to get the best contrast, which is ranging from 3000K to 5600K.

3000K warm color LED(minium)

5600K warm color LED(mixium)

The color temperature of LED light source is adjustable by straight screwdriver.

Application

BS-2045 series biological microscopes are ideal instruments for biological, pathological, histological, bacterial, immune, pharmacological and genetic fields. They can be widely used in education, medical and sanitary establishments, such as schools, hospitals, clinics, laboratories, medical academies, colleges, universities and related teaching labs and research centers.
