Overview
TEELEN XTL-20D trinocular fluorescence microscope is a continuous variable magnification microscope with continuously adjustable magnification to form a positive stereo image. Equipped with a long working distance imagery system and a large field of view eyepiece, it provides good Optical inspection and mechanical operation performance, and is an important tool for scientific research. This instrument is equipped with a fluorescent device, which can perform epifluorescence observation. It has Process Color LED fluorescence excitation components (G green, B blue, V purple, UV ultraviolet), which can be reasonably selected according to the sample or fluorescent pigment to achieve good fluorescence microscopy observation function.
Features
1. Continuous zoom design, adjustable magnification 7X~ 63X; 2. Configuration of long working distance imagery system (working distance 110mm); 3. Large field of view eyepiece WF10X, field of view φ 22mm; 4. Tri-eye observation head, hinged binocular, observation angle 45 degrees, pupil distance 48~ 75mm adjustable; 5. Left and right eyepiece tubes have visibility adjustment, range -5~ + 5; 6. Optional transmission and reflection illumination Illuminant (3W LED or 30W halogen); 7. Standard apocalyptic fluorescent illumination Illuminant (3W × 2 LED blue/green), optional purple/ultraviolet light; 8. The excitation filter group covers ultraviolet, violet, blue and green wavelengths.
Principle
The microscope is based on a continuous variable magnification Optical inspection system to achieve magnification adjustment and form a positive stereo image. Fluorescence observation adopts epifluorescence illumination technology, which generates excitation emission of specific wavelengths (such as ultraviolet light 360nm~ 370nm, violet light 390nm~ 400nm, blue light 460nm~ 470nm, green light 520nm~ 530nm) by exciting the color filter group. After irradiating the sample, fluorescence is emitted, and it is observed after being filtrated by the emitter. During operation, the adjustment of brightfield observation needs to be completed first, and then the adjustment of the fluorescent device is carried out.
Applications
Scientific research, precision manufacturing, electronic industry product inspection, college teaching, experimental research
Steps
1. Perform brightfield observation and adjust the Microscope correctly; 2. Select the fluorescence excitation component (G green, B blue, V violet or UV) according to the sample or fluorescent pigment; 3. Turn on the epifluorescence illumination Illuminant; 4. Adjust the excitation filter group to the corresponding wavelength; 5. Perform fluorescence microscopic observation.
Notice
• Fluorescence observation must be carried out after the correct adjustment of bright field observation; • When selecting fluorescent excitation components, it should be reasonably matched according to the sample or fluorescent pigment; • Wavelength range should be paid attention to when using different excitation filter groups (such as ultraviolet excitation wavelength 360nm~ 370nm, emitter wavelength 425nm); • Host power input is AC voltage 85V~ 265V 50/60Hz, output 12V; • Transmission and reflection illumination Illuminant are optional and need to be configured according to requirements.
