GFM-520 Falling FluorescencemicroscopeBy adopting an excellent infinity optical system and modular functional design concept, it can provide excellent optical quality and operational performance. Equipped with an infinity flat field achromatic fluorescent objective and a large field eyepiece without magnification chromatic aberration, the optical system produces clear and bright imaging with a wide field of view. Ideal design that meets ergonomic requirements, using a low position focusing handwheel and an inward facing objective lens converter to make the operation process more comfortable and easy. Fluorescence microscopy and transmission bright field observation can be performed Suitable for fields such as biopharmaceuticals, medical testing, and disease prevention.
Introduction to Imaging System:
GFM-520P computer modeluprightfluorescence microscopeGFM-520S Digital Typeuprightfluorescence microscopeThe system is designed to be eliteoptical microscopeA high-tech product has been successfully developed by perfectly combining technology, advanced photoelectric conversion technology, and cutting-edge computer image processing technology. Fluorescence images can be easily observed on a computer monitor, allowing for the analysis and grading of fluorescence spectra, as well as the output and printing of images.
Observation system:
Hinged observation tube: binocular observation tube, adjustable single view, tube tilted at 30 degrees, comfortable and beautiful. Three eye observation tube, can be connected to photography and video devices. Eyepiece: WF10X large field flat field eyepiece, with a field of view range of Φ 20mm, providing a wide and flat observation space.
Falling fluorescent lighting system:
Rotary table type falling fluorescence device: provides four types of fluorescence excitation groups: UV, V, B, and G. The rotary table structure enables rapid switching between different fluorescence excitation groups to achieve the ideal state. Mercury lamp lighting device: The 100W mercury lamp provides sufficient illumination for fluorescence observation. Built in variable field of view light bar: can effectively control the field of view range, and the center of the field of view light bar is adjustable.

Transmitting lighting system:
Built in halogen lamp lighting device: using 6V20W halogen lamp lighting (adjustable brightness), not only suitable for the usual bright field observation method, but also suitable for phase contrast observation method, which can observe clear microscopic observation images. Collector: A collector with a field of view light barrier.
Function extension:
By configuring phase contrast observation accessories and camera observation accessories, multiple observation methods can be expanded to meet the needs of different research work.
