Optical Instruments

When making very small watch components, magnifying instruments are required for working on and inspecting the parts. These include magnifying glasses, profile projectors, and stereo microscopes.

Microscopes

Stereo Microscope Olympus SZ 61 TR

This instrument provides high image quality and a large depth of field. This microscope was manufactured in 2005 and represents the new generation of the SZ series.

Olympus SZ61 TR stereo microscope with 10x eyepieces. 2005.

Along with good clarity and sufficient illumination, the optics provide significantly better resolution. The microscope has a zoom range from 6.7× to 45× combined with 10× eyepieces.

The trinocular optical head on the stand allows for mounting various types of photo/video cameras to take pictures or record videos and document the work.

Stereo Microscope Olympus SZ II

Olympus SZ II stereo microscope. General view.

The Olympus SZ II microscope from the 1980s provides a clear and minimally distorted image. It performs well even under less-than-ideal lighting conditions, which is a practical advantage. The SZ II has zoom, allowing magnifications from 14× to 80× when used with 20× eyepieces. Such high 80× magnification is necessary, for example, to inspect a freshly cut M0.5 thread. In practice, the microscope is essential for every stage, whether drilling, finishing, or assembly.
