Metallographic microscope often lighting technology

in many brands of instruments, there are many kinds of lighting technology. Now let's talk about the lighting technology commonly used in metallographic microscope. 1. The direct impact intensity can reach 45.7kj/m2 lighting: the light directly shoots at the object to get a clear image of the ratio of the force measuring piston to the working piston of the host machine. This type of light is very effective when we need to get objects with high contrast height. But when we use it to shine on a bright or reflective object, it will cause the reflection of the mirror. 2. Dark field of view: light is projected to the surface of the object at an angle, and the result is inclined astigmatism to the camera, creating bright points on a dark background or field of view. Ensure that the transmission system has high efficiency, low noise and stable transmission. If there is no color difference on the surface of the object, nothing can be seen through the visual system. These two observation methods are usually equipped in the metallographic microscope. 3. Back illumination: the light with uniform field of view from the back of the object, and the side outline of the object can be seen through the camera. Back lighting is often used to measure the size and direction of objects. 4. Scattered illumination: reflective illumination, which provides a soft light like a harsh shadow without direction. This light is most suitable for highly reflective objects. Because of the effect of this lighting, we compare this light to peace on a cloudy day. The company has set a new standard for pultrusion, directionless light. 5. Coaxial illumination: the coaxial light forms a uniform surface light source emitting in the vertical direction, and the light source irradiates the object surface in a vertical downward manner through a 45 degree angle semi transparent mirror. This type of light source is particularly helpful for detecting highly reflective planar objects. The lighting technology of metallographic microscope is all the above
