Scope slides with 0.1 and 0.01 mm graduations are used to calibrate the objectives and eyepieces of your microscope, i.e. to determine the size of the optical field of view. They are particularly recommended for digital photography, where, after calibration, it is possible to determine, for example, the size of the object under examination.
The slide can be used for both biological and stereomicroscopy, thanks to the two different scales. Its size is 76x26 mm and its thickness is about 1 mm.
