LBT-5000D Inverted Metallurgical Microscope (Petrographic Analysis Software)

Description

Main features:

It can be used for a variety of imaging modes, including brightfield, polarized light, and DIC.

Optical System:

Infinity‑corrected apochromatic optical system.

LED illumination offers adjustable brightness and stable luminance, delivering true‑color images across all intensity levels. It boasts a long service life, eliminating the need for frequent bulb replacements. With minimal heat generation and no risk of overheating, it operates without cooling fans, fostering a quiet, distraction‑free working environment. Thanks to these advantages, LED lighting is increasingly replacing traditional halogen lamps as the preferred light source for microscopes.

A unique industrial camera mounting position places the camera on the left side of the microscope, ensuring unobstructed access to the sample. A universal stage‑adjustment handle enables convenient one‑hand operation.

The LBT-5000D inverted metallographic microscope positions the specimen above the objective, enabling observation from below, and is widely used in industries such as steel, automotive, machinery, and electronics. For specimens that are uneven or relatively large, placing them on the stage allows for convenient and rapid examination. The WY-5000 is suitable for handling large, heavy samples weighing up to 5 kg, supporting magnifications ranging from tens to thousands of times. When paired with metallographic analysis software, it meets a variety of metallurgical imaging and analytical needs, helping you gain deeper insights into how different processing techniques affect your samples.
