Product Description

 

BS-2064 Biological Microscope

Introduction

BS-2064 series microscopes are high end microscopes which are specially designed for college education, medical and laboratory teaching and research. With excellent infinity color corrected optical system, new upgraded Koehler illumination system, presents a clear & bright micro-image under each magnification. Ergonomically designed to provide better comfort and experience. The modular design allows for various viewing modes such as brightfield, darkfield, phase contrast, fluorescence and simple polarizing. This series microscopes are widely apply to clinical diagnosis, teaching experiment, pathological test and other micro-fields.

Features

1. High rigidity body structure
 

Fire-new designed integrative Y-shaped body, all-metal diecasted under high pressure, High image quality with high stability under every magnification observation. Ensures the test precision of multi-channel fluorescence diagnosis.
 

2.High precise low position focusing system

 

Low position high precise coaxial coarse and fine adjustment, with ergonomics design, create the best comfort to operator.
 

 

3. Screwdriver storage device

Quintuple turret phase contrast unit with 10X/20X/40X/100X Infinite plan phase contrast objective for phase contrast and bright field observation.

The screwdriver storage device makes full use of the space of the microscope, the screwdriver at fingertips enables users to improve work efficiency.
 

4. Mechanical stage
 

(1) Standard 175×145mm right-hand double-layer mechanical stage, damping double slice clamp design, can place two slices at the same time for inspection and comparative analysis.
(2) Optional 150mm×162mm ceramic spray mechanical stage, which is not only wear-resistant and anti-corrosive, but also can reduce platform deformation caused by temperature changes.
(3) Optional 187×166mm super large double-layer mechanical stage, two-way linear rail transmission, left and right hand positions are optional.
 

5. Safe carrying design

 

The rear side of the microscope has been designed with a handle position, which makes it safe and easy when carry the whole microscope.
 

6.Koehler Illumination System
 

6V 30W transmitted system, presents a bright and uniform field under every magnification. New designed telecentric Koehler illumination system, working with N.A. 1.2/0.22 swing-out achromatic condenser, applies to 2X-100X observation.
 

7.Disc switching mechanism for filters
 

Newly designed high-precision disc switching mechanism, is easy to change filters. It guarantees the exact position of the switched filters, can be equipped with six fluorescence filters at most. Selecting driftless high-performance fluorescence filter system, ensures an accurate experiment result of FISH. High transmittance of spectrum without a cross color but a high S/N ratio, promotes dramatically fluorescence imaging contrast. The filter with stray light elimination technology, presents high contrast between image and its background, achieves the best effect of observation.
 

 

8. Efficient illumination system

High-graded SiO2 quartz, with the characteristics of refractory, corrosion-resistant and high UV through rate makes the illumination more uniform and brighter. High temperature resistant composite plastic, with heat insulation, effectively prevent the heat of illuminator from transferring to the body. Alterable field diaphragm with adjustable center, effectively reduce the stray light to obtain the best observation effect.
 

9. Semi-apochromatic fluorescence objectives

New professional infinity plan semi-apochromatic fluorescence objectives, the best choice for fluorescence observation. Aberration correction and large numerical aperture which is 25% bigger than ordinary objectives, present brighter and clearer image. Adopting high quality environmental protection optical materials, show excellent effect in fluorescence observation. With advanced multi-coating wide-band technology, take the obvious advantages in bandwidth and UV transmittance.
 

10. High-performance fluorescence filters

High performance fluorescence filters, high spectral transmission, good depth and gradient of spectral lines. No cross color, high S/N ratio, high image contrast. Adopting stray light eliminating technology, high contrast between image and background, creates a perfect observation effect.

11. Power supply for mercury lamp
 

New digital power control system, displaying operating time and current value, clearly show you the working state of mercury lamp.
