LBT-LM20 Series Portable On-Site Metallographic Microscope

Description

Product Introduction:

A portable metallographic microscope, also known as an on-site metallographic microscope, does not damage the specimen during inspection, thereby preserving its integrity. It is widely used in industries such as aerospace, mechanical engineering, automotive manufacturing, metallurgy, roll production, and the fabrication and inspection of boilers and pressure vessels, as well as in petrochemicals, railways, shipbuilding, power plants, equipment installation, large‑scale mold making, nondestructive testing, quality supervision, and physicochemical laboratories. It can also be employed in factories and laboratories for assessing casting quality, inspecting raw materials, or conducting microstructural analysis after material processing.

Product Features:

1. It employs a standard 195 optical system and is equipped with an achromatic metallurgical objective lens featuring a flat field.

2. Wide field of view, uniform background illumination, high imaging resolution and clear image quality, with a high eye point for more comfortable observation;

3. Equipped with a 3W high‑color‑rendering LED light source, it supports power supply from adapters, power banks, smartphones (via reverse charging), and in‑vehicle power sources, among others.

4. It employs a coaxial coarse‑fine focusing mechanism that complies with national industry standards for metallographic microscopes, and features a two‑stage differential handwheel to enable rapid and precise focusing on the target.

5. The camera can be used in conjunction with the observation tube for simultaneous viewing, with image capture synchronized to smart devices such as smartphones and tablets.

6. Optionally equipped with a digital imaging system (industrial camera) and metallographic grading software; additional accessories can also be upgraded to accommodate a wider range of operating conditions.

7. Applicable scenarios: factory inspection and testing, field metal observation, boiler surface inspection, teaching laboratories, and more.

8. Application scope: metals, minerals, ceramics, electronics, and more.
