A portable microscope for measuring size and depth of objects. The Depthscope is a versatile tool for use in the workshop, the laboratory or for field studies and is supplied in a polished wooden case. 

With the Dephscope you can measure thickness of photographic film, depth of coatings on opaque materials, pits and scratches, depth of blind cavities, cracks in opaque and translucent materials, solder thickness, silk screen ink coating, machined surfaces, surface corrosion, indentations etc. 

Special Features:

  • Magnification x200
  • Direct Reading to 10 micron
  • Repeatability to 2 micron (Estimations to 5 microns or better without the use of verniers)

Built entirely in metal with quality glass optics the microscope is robust and precision engineered to meet the rigorous of continuos use in a variety of environments. A battery powered (2 x C type) vertical thru lens illuminator is fitted above the objective lens. 

Depth Measurements
In use the microscope is focussed on one surface and the zero datum mark adjusted to coincide with zero of the depth scale. The focus is then adjusted to the second surface and the separation of the two surfaces or depth is read directly from the scale. 

The instrument which has a fixed calibration is focussed by means of the rotating central body system.
