What are the differences between a stereo microscope and a biological microscope?
Stereoscopic microscope, also known as stereomicroscope, differs from biological microscope mainly as follows:
1, The working distance of stereomicroscopes is relatively large, usually up to 50mm or even 150mm; The working distance range of biological microscopes for detecting objects rarely exceeds 20mm.
2, Stereoscopic microscopes can hold taller and thicker objects such as integrated circuit blocks, larger workpieces, screws, thicker objects, etc., while biological microscopes can only hold thin films, glass slides, etc.
3, The depth of field range of a stereo microscope is relatively large, reaching up to 10mm. By adjusting the focus ring, clear images can be seen over a considerable range; However, the biological microscope may not be able to see clearly by slightly rotating the focusing ring.
4, Stereoscopic microscopes can see three-dimensional images due to their wide depth of field. However, the magnification is relatively small, and the maximum magnification of a stereomicroscope is usually around 200 times; The maximum magnification of a biological microscope is generally around 2000 times, and the characteristic parameters of a biological microscope are exactly opposite to those of a stereomicroscope. So, the adaptation range of stereomicroscopes and biological microscopes is different, and the structure of the lens is also different.
