CZ Fluorescence module with Blue and Green Excitation filters, trinocular tube and power supply with mercury lamp (100 hour life) uses GCQ-100 mercury

The CZ-FL/KIT, an epi-fluorescent kit, also known as the incidence fluorescent kit or reflection fluorescence kit. It is an accessory device that excites and emits fluorescence for fluorescent microscope illumination, forming an illumination system that consists an illumination source that emit ultraviolet light, a configured fluorescent condenser, and filters for excitation and emission of fluorescence etc. Fluorescence microscope requires a complete set of filters. The fluorescence excitation block is the core component used to excite fluorescent specimens and observe fluorescence in a fluorescence microscope. The excitation and emission filters, after combinaton, are placed in a filter cube. When the user replaces the filter, it is relatively convenient. The component consisting of several filter blocks in the excitation module includes: • Exciter filter: selects the light that passes through a certain wave band to excite the specimen to produce fluorescence. • Dichroic mirror (commonly known as a mirror): set at a 45 degree angle in the cube, reflect the excitation light downwards and transmit the fluorescent upwards. • Barrier filter: transmit the emitted light, that is, fluorescence, and at the same time block the reflected light in various stray light and excitation light Fluorescence is excited by light of a specific wavelength, and the emitted light that is excited has also a specific wavelength. Therefore, it is necessary to select suitable excited blocks (mainly selecting the light wavelength parameters of excitation light filter, dichroic mirror and barrier filter). The excitation module is generally named after the basic color tone. The first letter represents the excitation spectrum region of the wavelength, that is, the color tone. For example, UV represents ultraviolet light, V represents violet, B represents blue, and G represents green. The subsequent letter represent the glass, and the numbers represent model features. For example, BG12 is a kind of blue glass, B is the first letter of blue, and G is the first letter of glass.
