Sanma Tiltable Binocular, Color : Black, White

Some of the most common applications include medical diagnostics, forensic investigations, scientific research, and educational purposes. Medical professionals use binocular microscopes to examine tissue samples and diagnose diseases. Scientists use them to study specimens down to the cellular level.200X magnification range using four achromatically-corrected objective lenses and two pairs of eyepieces. The adjustable binocular viewing head uses sliding interpupillary adjustment, and can be rotated 360 degrees.When someone looks through a pair of binoculars light enters through a lens, called an objective lens, in each side. The objective lenses turn the image being viewed upside down.Rotating the central focusing ring engages the internal shafts. Then, the tubes that fix internal lenses (concave lens) move so that the binoculars focus. Because objective lens and eyepiece lens are fixed, binoculars can have a highly airtight structure.
