1) Low voltage tungsten filament lamp

    The filament is composed of tungsten filaments and sealed with argon gas. It is usually used for 6 V 15 W and 12 V 30 W. Suitable for primary and intermediate metallographic microscopy observation. However, when using high-power microscopy, the exposure time is slightly longer, which is widely used due to its low cost and long lifespan.

    2) Halogen lamp

    Halogen lamps are brighter than incandescent lamps, with spectra close to sunlight, and color temperature changes little over time. At the same time, it has a small size, less heat, and high brightness per unit area. Also known as a cold light source. More suitable for micro photography and projection, commonly used 6v 12w, 12v 50w, and 12v 100w.

    3) Xenon lamp

    Xenon lamps use erbium gas as a light emitting element and are typically used as short arc xenon lamps. Its spectrum is close to daytime, with high brightness, good color quality, and a color temperature of about 6000 K. Xenon lamps are widely used in high-speed Color photography. Large field projection and video observation. Because xenon lamps need to be illuminated by starting devices, their structures are more complex and bulky, and their prices are more expensive.

    4) Ultra high pressure mercury lamp

    This is the high brightness ultraviolet light from a point source. Suitable for microscope fluorescence observation mode, the spectrum is line spectrum, and the ignition start device is usually HBO 100W and HB0 200W.

    5) LED lights

    Energy saving: The energy consumption of white LED is only 1/10 of that of incandescent lamps and 1/4 of that of energy-saving lamps.

    Longevity: With a lifespan of over 100000 hours, it can be considered a once and for all solution for ordinary household lighting.

    Can work at high speeds: If energy-saving lights are frequently started or turned off, the filament will turn black and quickly break, making it safer.

    Solid state packaging: It belongs to the cold light source type, so it is easy to transport and install, and can be installed in any micro and enclosed equipment without fear of vibration.
