Metallurgical Microscope

A specialized microscope designed for looking at cross-sections of metal targets (metallurgical mounts). Typically inverted, these metallurgical microscopes employ high-resolution objective lenses with very short working distances. While these systems work well for this type of analysis, they are very limited in their range of applications.

Inverted Trinocular Metallurgical Microscope

Functions & Features

1. Infinity-corrected optical system.

2. Magnification range: 40× ~ 1000×.

3. Infinity Plan Objectives: 4× ~ 100×, Wide field Eyepiece 10x / φ20mm.

4. Observation tubes can be adjusted up and down 180 ° to accommodate with different users.

5. High quality Reflected Illumination system.

6. Light source 6V/30W halogen lamp.

7. Adopt safe electrical system: low voltage DC input 6V5A.

Key properties it can analyze include

Microstructure

Examines grain size, shape, and distribution, providing insights into material properties like strength and ductility.

Metallographic Microscope with LWD Objectives

Phase Composition

Identifies different phases within an alloy or composite, helping assess heat treatment effects and material homogeneity.

Inclusions and Impurities

Detects non-metallic inclusions or impurities that can affect mechanical properties and performance.

Surface Defects

Identifies cracks, voids, and other surface defects that may compromise material integrity.

Layer Thickness

Measures coatings or layers on a sample, such as oxide layers or surface treatments.

Grain Boundaries

Observes boundaries between grains, which impact material strength and resistance to corrosion.

Metallurgical Microscopes Parts and Functions

The main components of a metallurgical microscope are the optical system and the illumination system. The optical system typically consists of

Eyepiece lens, which is what the observer uses to see the image
Relay system, which reflects and enlarges the image
Objective lens, which takes in the image from the sample on the stage

The illumination system is designed to prevent glare from light bouncing off the surface of the sample and consists of

High-intensity light source
Condenser lenses
Aperture diaphragm
Plane glass reflector
Colored or polarizing filters

Limitations of Metallurgical Microscopes

1. Objects can only be viewed top-down

2. Best-suited for observation in the middle to high magnification range

3. Lens magnification is changed with a revolver, cannot change while continuously observing the target

4. Mounting attachment is required to add a camera

5. Various filters are available to provide multiple observation methods

6. Extremely shallow depth-of-field, which means that a defective part may be overlooked

7. Short working distance requires samples to be processed before being imaged

8. Complicated to operate, requiring users to be thoroughly trained

9. Eye pieces cause fatigue

Metallurgical Microscope Types

Metallurgical microscopes are divided mainly to 4 categories:
1) Upright Microscopes with reflected light only, in which the light comes from top lamp-house and is used for non-transparent samples

2) Upright Metallurgical Microscopes with reflected and transmitted lights, in which light can come from top and bottom light sources and can be used to examine the transparent and non-transparent samples.

3) Inverted metallurgical Microscopes which includes a lamp house for reflected illumination. Bioimager offers economic external light source to be able to use for tra

4) Boom Stand Metallurgical Microscopes

Application of Metallurgical Microscope

(1) Metallographic inspection of welding;

(2) Metallographic inspection of cast iron;

(3) Quality inspection of heat treatment;

(4) Inspection and evaluation of microstructure of various metal products and raw materials;

(5) Low magnification defect inspection of cast iron, cast steel, non-ferrous metals and raw materials;

(6) Determination of metal hardness (HV, HRC, HB, HL) and grain size rating;

(7) Determination of non-metallic inclusions;

(8) Depth determination of decarbonized layer/carburized hardening layer, etc.
