Description
BDS400-FL fluorescence microscope is our best-selling biological laboratory microscope. The superior optical system, coupled with our EPI fluorescence device, can present good observation effects in the eyepiece. This fluorescence microscope can be installed with up to 4 sets of fluorescence filters, generally with four colors of filters B/G/Uv/V. There are two options for fluorescent light sources: mercury lamp and LED. You need to confirm clearly before purchasing.
This standard trinocular head can be used in conjunction with our digital camera. Inverted microscopes can be used to observe living biological cells. In addition to fluorescence observation, it can also be used for bright field observation and phase contrast observation. Powerful, one unit can realize three observation methods. A variety of accessories are available.
| Features of BDS400-FL Fluorescence Microscope
- It can also meet the requirements of fluorescence observation, bright field observation, and phase contrast observation.
- In addition to the standard objective lens, professional fluorescence objective lenses are also available.
- Inverted microscopes are more versatile and easier to operate. A variety of parameter configurations can be customized.
- N.A. 0.30 LWD condenser, Working distance: 72mm (with condenser), 195mm (without condenser)
- Large stage, Size: 240mm（X）× 210（Y）mm
- Mechanical Stage for 96 holes plate, Moving range: 128mm（X）× 80（Y）mm
- Quintuple Nosepiece, equipped with L Plan FL PHP 10X/20X/40X objectives, which can be used for phase contrast observation.
- Light Distribution: Both 100:0 (100% for eyepiece) and 80:20 (80% for trinocular head and 20% for eyepiece).

| Illumination of BDS Inverted Fluorescence Microscope
Regarding fluorescence light sources for fluorescence microscopes, there are two commonly available options: 100W mercury lamps and 5W LED lamps.
Under mercury light source, 1~4 groups of fluorescent filters can be added. There is no change in appearance.
For LED light sources, groups 1 to 3 of fluorescent filters use our new integrated fluorescent device, and 4 group uses the previous style, as shown in the figure below.
