How to choose a high-quality microscope
Microscopes are precision optical instruments, and their core technology is optical technology. The quality of products depends on the optical system (including lighting systems, objective lenses, etc.), which is also the basic principle for purchasing microscopes. In the imported microscope manufacturers (Zeiss, Leica, Nikon, and Olympus), the quality varies. Users should analyze rationally during the selection process and avoid going astray, which may lead to inevitable economic losses.
The following is an explanation of the key technical indicators that should be evaluated during the selection process:
1、 Imaging quality
We mainly use optical imaging principles to obtain microstructure images using microscopes, and then conduct qualitative and quantitative analysis of the images, so the quality of imaging is a key indicator. Clear images are referred to as sharp images in the field of metallography. To obtain sharp images, four basic conditions must be met: high contrast, high brightness, good color reproduction, and high resolution. Contrast, brightness, and color restoration are precisely the areas that users tend to overlook when selecting, blindly pursuing resolution and resulting in selection failure.
2、 Mechanical stability
Having good imaging quality is not enough, but it should continue to maintain a high-quality state over time. We call this' mechanical stability 'because microscopes are not low value consumables and their normal service life should be over 30 years. In this regard, it is recommended that users focus on the following points: 1. Raw materials 2. Manufacturing accuracy 3. Mechanical design 4. Origin
When comparing the above indicators, users who have the necessary conditions should bring their own samples for "on-site inspection", and only when there is comparison can identification be made.
