Product Description

BS-2044F(LED) LED Fluorescent Biological Microscope

BS-2044FB(LED)   

 

   BS-2044FT(LED)

Introduction

BS-2044F(LED) series LED fluorescent microscopes are high quality biological microscopes, which are specially designed for biological and medical research and teaching experiments for colleges, universities, laboratories and related institutes. With infinity color correction optical system and excellent Koehler illumination system, BS-2044F(LED) can get uniform illumination, clear and bright images at any magnification. These microscopes can be used for teaching experiments, pathological examinations and clinical diagnosis. With outstanding functions, excellent cost performance, easy and comfortable operation, BS-2044F(LED) series microscopes present over expected and splendid micro images. BS-2044F(LED) with B4 LED fluorescence module can be used for diagnosis of tuberculosis (TB).

Feature

1. Infinite Color Corrected Optical System provides sharp and comfortable images.
2. Wide-field high eye-point eyepieces and plan achromatic objectives and semi-APO fluorescent 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(B4) for tuberculosis examination is available. Except for TB test module B4, you could select B1, G1, UV2 fluorescence modules according to different applications. You can also choose several modules and replace them when you need.


7. The Single-band LED fluorescent attachment have light intensity control function, with 6V/2A DC power supply, external transformer, easy connection and safe use. There is a switch and easy to change from fluorescent observation to bright field observation with transmitted illumination.


 
8. Semi-APO fluorescent objectives are optional. These objectives have large numerical aperture, provide high-resolution, high contrast microscopic images. We also can provide objectives without cover slip corrections, which is used to observe smear slides.
