Product Overview
BestScope continues to address the research needs of specialised fields such as pathology, cytology, and virology by continuously optimising and upgrading the BS-2081 series of scientific-grade upright microscopes, offering near-perfect optical performance and mechanical design. The NIS Infinity Optical System delivers precise imaging and excellent chromatic aberration correction. With high colour fidelity illumination, high-quality optics, and comprehensive accessories, these microscopes are ideal for advanced life science research requiring dark-field observation, differential interference contrast (DIC), or high-performance fluorescence imaging.
In addition, a wide range of motorised and intelligent components, combined with powerful imaging software, supports both rapid sample overviews and detailed inspections. This enhances workflow efficiency, reduces user fatigue, and significantly improves comfort and productivity. Whether in clinical or research laboratories, the BS-2081 series provides an optimal microscopy imaging solution.
Features
- Sapphire Glass Stage (Optional)
The mechanical stage with a sapphire glass insert is optional. It is highly durable, scratch-resistant, and allows users to clean the stage surface easily. - Single-Handed Slide Placement
The specially designed slide clip enables users to place slides with one hand, improving convenience and efficiency during operation. - Tilting Trinocular Head (Optional)
The eye tube angle is adjustable from 0° to 35°.
Digital cameras or DSLR cameras can be mounted on the trinocular port.
The beam splitter offers three positions (100:0, 20:80, 0:100) to accommodate different imaging needs.
The splitter bar can be installed on either side, depending on user preference. - ECO Function
The transmitted light automatically turns off 30 minutes after the operator leaves, helping to conserve energy and extend lamp life. - Low-Position X-Y Knobs
The height of the stage control knobs can be adjusted up or down by 18 mm to ensure a comfortable hand position. The tension of the X-Y control knobs is also adjustable to suit user preferences.
Applications
The BS-2081 research microscope is an ideal instrument for applications in biology, histology, pathology, bacteriology, immunology, and pharmaceutical research. It is widely suitable for use in medical and healthcare institutions, research laboratories, academic institutes, and university teaching laboratories.
