Description
The BDS500-FL inverted fluorescence microscope is a professional experimental instrument. In addition to the eyepiece channel, this model can also be connected to a digital camera and a SLR camera. The BDS500-FL microscope is one of our top-of-the-line biological laboratory equipment. It is mainly used to study organisms with fluorescent properties, ordinary organisms, etc. It can be used not only for fluorescence observation but also for bright field observation and phase contrast observation.
This is also a trinocular microscope. After connecting to the digital camera, you can use software to measure and shoot observation images. The EPI fluorescence device can add up to four sets of fluorescence filters: Blue/Green/Ultraviolet/Violet.
| Features of BDS500-FL Inverted Fluorescence Microscope
- Trinocular biological microscope, connected to digital camera and SLR camera.
- Magnification 40X~400X, multiple optional objective lenses.
- Three observation modes: fluorescence, phase contrast, bright field.

| Fluorescence Illumination
Regarding fluorescence light sources for fluorescence microscopes, there are two commonly available options: 100W mercury lamps and 5W LED lamps.
Our LED fluorescent device is now updated. For groups 1 to 3 of fluorescent filters, we use an integrated fluorescent device, which installs both the light box and the fluorescence filter in the same device. If there are 4 group of fluorescence filters, the previous device will still be used.
