Introduction:

BestScope continues to explore the research needs of specialized fields such as pathology, cytology and virology, and continuously optimizes and upgrades the BS-2081 series of scientific grade upright microscopes to have near-perfect optical performance and mechanical structure design. NIS Infinity Optical System has precise imaging and chromatic aberration correction capabilities. The illumination system with high color reproduction, high-quality optics and full-featured accessories makes these microscopes ideal for cutting-edge life science research where darkfield of view, differential interference contrast or high-performance fluorescence are required. In addition, a wide range of motorized and intelligent components and powerful imaging software meet the needs of quick sample overview and detailed sample inspection, making repetitive tasks easy and greatly increasing ease and comfort for maximum productivity. No matter in a clinical laboratory or a research laboratory, the BS-2081 series microscopes provide the ideal microscopy imaging solution.


Features:
 

 

1. Sapphire Glass Stage is optional.                      Mechanical stage with sapphire glass insert is optional, it is endurable, never could be scratched and allows users to clear the stage easily.

2. Put Slide by One Hand.                                                     
It is easy for users to put slides by one hand due to the special designed slide clip.

 

3. Tilting Trinocular Head is optional.   

1. The eye tube can be adjusted from 0°-35°.
2. Digital cameras or DSLR cameras can be connected to the trinocular tube.
3. The beam splitter has 3-position (100:0, 20:80, 0:100).
4. The splitter bar can be assembled on the either side according to user's requirements.

 

4. ECO Function.                                                                        The transmitted light would be off automatically after 30 minutes from operators leave. It can not only save energy, but also keep the lamp life longer.

5. Low Position X-Y Knobs.                                                     The height of the stage control knobs can be adjusted up or down by 18mm to ensure a comfortable hand position, the tension of X-Y control knob also can be adjusted.

6. BS-2081L has Intelligent operating system.

1. Coded Nosepiece with light intensity memory function.

The BS-2081L microscope can memorize the illumination brightness when using each objective. When the objective has been changed, the light intensity will be automatically adjusted to reduce visual fatigue and improve work efficiency.
2. Use a dimming knob to achieve multiple functions.

One Click: Enter standby status
Double Clicks: Light lock or unlock
Rotation: Adjust brightness
Press + Up-spin: Switch to the upper light source
Press + Down-spin: Switch to the under light source
Press 3 seconds: Set the time of turning off the light after leaving.
3. The display of microscope working status.

The LCD on the front of the microscope can display the working status of the microscope, including magnification, light intensity, sleepy model and so on.
4. Color temperature adjustment function.

The color temperature can be adjusted from yellow to white, which can lead to a better contrast and meet the requirements of various research.

Accessories:
 

1. N-PLN Series Plan Objectives                                        The plan objectives can provide flat high transmittance image from visible light to NIR light. They are usually used for bright-field viewing as the high signal-to-noise, high resolution and high contrast features.

 

2. N-PLN PH Series Plan Phase Contrast Objectives             These plan phase contrast objectives are specially designed for phase contrast observation. They are good choice for clinic and scientific research. These objectives can provide advanced flat image of 25mm FOV under transmitted bright field.

 

3. N-PLFN Series Plan Semi-APO Fluorescent Objectives   Owe to the multilayers coating technology, these Semi-APO objectives can compensate the spherical aberration and the chromatic aberration from ultraviolet and infrared light. High-sensitive fluorescence performance of the objectives ensures the sharpness, definition and color rendition of images.

4. N-PLPN Plan Apochromatic Fluorescent Objective          The newly developed advanced apochromatic objective lenses have high level of chromatic aberration correction capability and high resolution, ensuring a high level of wave-phase contrast correction with full field of view, these APO objectives are ideal for routine laboratory observation work and digital imaging.

 

5. Bright field viewing                                                             Brighter image, high resolution and flatness, suitable for all the magnifications.

 

6.  Fluorescent viewing                                                       The compact epi-fluorescent components include noise elimination feature which ensures images captured are bright, with high contrast and high signal-to-noise ratio.
