The technical parameters of compound microscopes mainly include the following aspects:
Optical system: Compound microscopes are usually equipped with multiple objective lenses, such as 4x, 10x, 40x, and 100x. Through the combination of objective lenses and eyepieces, the maximum magnification can reach 400x or higher.
Observation mode: Compound microscopes support a variety of observation modes, including bright field, fluorescence, and DIC (differential interference contrast) observation. For example, some models of microscopes also support DIC kits for 10x, 20x, 40x, and DIC observations.
Objective lens: Common objective lenses include 4x (N.A. 0.1), 10x (N.A. 0.25), 20x (N.A. 0.4), 40x (N.A. 0.65), and 100x (N.A. 1.25). These objective lenses are suitable for different observation needs.
Lighting device: Compound microscopes are usually equipped with efficient long-lasting white light LED light sources with a lifespan of more than 20,000 hours. Some models also support stereo coaxial lighting systems to provide better lighting effects.
Camera and image processing: Modern compound microscopes are equipped with high-resolution sCMOS cameras with more than 20 million pixels. Image processing modules support continuous observation and research of microscopic objects such as cells and bacteria.
These technical parameters make compound microscopes widely used in fields such as microbiology, cytology, parasitology, oncology, immunology and genetics.
