Ergonomic design, tilting binocular head, interpupillary distance 50-75mm, 360°rota table. So users can easily have a understand of the viewing height.

One module casting stable mechanical main body made of high quality aluminum alloy, guarantee the high image quality, main body surface pain is with dusting technique, anti-corrosive and anti-abrasion, perfect for human body temperature, each accessory is with optical coating with hard surface, even in bad condition, this microscope can also be used for a long time.

Safe and high efficiency LED illumination

With CREE 5W high power LED light, no need to use filter, offer natural light light stable, safe, not easy to heat, environmentally friendly, long life time.

Users can realize different cell cultivation methods.

Simple, stable and smart main body makes users more space to install all kinds of accessories, such as  petri dish, culture bottle,perforated plate, and stage can be equipped with moving scale, users can move the sample by turning the XY coaxial knob.

22mm plan high eyepoint eyepiece

20X phase contrast objective as standard accessory

With PH slide makes live cell and un-dyed cell better image.

New intelligent ECO system, economic environmentally friendly infrared induction system. When users is out for a certain time or back after a while, this system will shut down or restart automatically, save energy.

Marking objective

When you are carrying on live cell observation, you can use the marking objective to mark your sample, easy for you to check the same area and also the cell extraction.

.NewBridge Engineering Ltd. also offer you all kinds of camera, CCD, CMOS, HDMI, WIFI…..and professional microscope software, easy for you daily work.
