Optical platform, also known as optical breadboard, optical table, scientific
desktop, experimental platform, for the level, stable tabletop, the general
platform need to be vibration isolation and other measures to ensure that it is
not interfered by external factors, so that the normal scientific experiment and
the instrument is not Affected by vibration performance. At present, there are
two major categories, active and passive. The passive and rubber and air float
two categories.
Optical platforms, including motorized linear stage, manual rotation stage,
are widely used in optics, electronics, precision machinery manufacturing,
metallurgy, aerospace, aerospace, navigation, precision chemical and
non-destructive testing, as well as other mechanical industry's precision test
equipment, equipment, vibration isolation of key devices.
With the advancement of advanced equipment and processes, nano-scale
measurement becomes possible.
For example, an imaging system that uses a microscope to highly magnify the
image, and the microscope and the camera lens together determine the image at
each point on the photo paper. If, in the exposure process, each part of the
optical system (the illumination system, the sample, the microscope optical
system, the imaging optical system, and the photographic paper plane) moves
precisely together, there is no relative displacement and the imaging will be
very clear. If the sample moves relative to the objective lens, the image will
be blurred. In optical interferometry, holography, and the use of similar laws,
controlling relative motion is important.
Therefore, its stability will be affected by many factors. Such as the
external vibration source, the weight of the system, the structure of the
optical platform, and so on.
