Product Description

Introduction

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.

Feature
 

1. Intermediate device for professional conoscopic observation
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.
 

2. Reflected illuminator
Reflected illuminator with polarizer and beam splitter, field and aperture diaphragms adjustable.
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.

3. Polarizer bayonet
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.
 

4. Large stage
Large circle metal stage, 160mm diameter, 360° rotatable, can be positioned with lock screw at any angle. The stage is anti-corrosive and anti-friction as it is coated with graphite. The scale lines printed by special material can avoid fading or wear-out after long-term operation.
 

5. Achromatic condenser

N.A 1.2 swing-out achromatic condenser, center adjustable, horizontally insert, vertically adjustable up and down. Adjustable aperture diaphragm with scale remedies the disadvantage of fixed condenser, provides ample uniform light and clear image for different magnification observations.
 

6. Focusing mechanism

Low position focusing knob for comfortable operation. It is equipped with a coarse and fine adjustment device for elasticity, a coarse and fine adjustment maximum limit device, and a random limit device. The random limit device can be used for quick replacement of slices, protection of slices and objective lenses.
 

7. Stable frame

Y-shaped frame adopts the design principle of roof. As the main load bearing part, solid column structure eliminates most impact force to ensure stable operation. New designed lamp-house inserts into the concave part on the back as a tail fin, imaginative and beautiful. Surface uses special spray powder, protective, decorative, wear and solvent resistant.
 

8. Illumination system

New designed reflected and transmitted lamp-house with 12V/50W halogen bulb, the center of the filament is preset. Optimized and upgraded light source spotlight system improve light source efficiency. 100-240V wide voltage system with stable output voltage lengthens the life time of bulbs. The main switch of the electrical system decreases consume in standby.

1. Long working distance plan destressing objectives
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.
