1.There should be provision for focusing the source relative to the lamp condenser/diaphragm. 2.If the microscope requires different light sources, they should be easily interchangeable, ideally without upsetting the lamp alignment. 3.Lamp tilt, rotate, and distance from the microscope must be easily adjustable, and once set, should be sufficiently rigid to resist accidental misalignment. 4.Filters […]

1.Its intensity should be continuously variable over the entire range required by the microscope without change in color, uniformity or effective size. 2.It must have the highest possible intensity (luminous flux emitted per unit area), distributed uniformly across its area.

1.It should have the highest possible aperture (lowest possible f number) for the efficient collection of light radiating from the source 2.It should be as powerful as possible in order to project the required filament image in the shortest possible distance. 3.It should have as large a diameter as possible to enable illumination of the […]

One of the most essential part of the microscope is the microscope lamp. It is the next most significant part that a microscope user needs because it is the means by which it is illuminated. Microscope lamps come in a diversity of envelope shapes (cylindrical, rounded envelope), mounting fixtures (bayonet, screw-thread or pin base) and […]
