BS-2081L
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.
Put Slide by One Hand. It is easy for users to put slides by one hand due to the special designed slide clip.
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). The splitter bar can be assembled on the either side according to user’s requirements.
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.
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.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.
(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.
