BLD-330DM research grade digital inverted phase contrast biological microscope consists of a VMB600PH trinocular microscope and an screen integrated machine. It is equipped with a phase contrast device, a large field eyepiece, and an infinite flat field achromatic phase contrast objective lens, providing a large and clear field of view.
Phase contrast microscope utilizes the difference in refractive index and thickness between different structural components of an object to convert the optical path difference through different parts of the object into the difference in amplitude (light intensity). It is an infinite bidirectional chromatic aberration correction optical system with a focal length of 45mm, which uses the principle of optical phase contrast to make unstained low contrast specimens clearly visible. It is mainly used to observe live cells or unstained tissue sections, and can also be used to observe stained samples lacking contrast. Total magnification: 40X-400X.
Aluminum alloy one-time molding technology for all metal streamlined body, with a surface sprayed with nano silver ion antibacterial coating, effectively inhibiting the proliferation and spread of contact microorganisms. 90~230V wide voltage power adapter, panel supports ECO energy-saving and brightness following (LIM intensity management) functions, supports stepless brightness settings, and supports dual lighting power supply.
