Meiji Techno offers with the FU3050 series focus blocks an attractive way to build a custom microscope.
Image shows mounting for optional Z-axis micrometer and bracket for 38 mm pole mount.
Designed for Brightfield / Darkfield standard infinity corrected  EPI metallurgical objectives, the quintuple nosepiece accomodates five of them. With Mitutoyo style objectives, because of the larger diameter, only two will fit simultaneously. An adapter overcomes this problem and allows to fill all positions with Mitutoyo or workalike objectives.
Focus block can be mounted on a wide variety of boom or pole stands (38 or 20 mm dia) or simply be bolted on to any vertical plane that accommodates the bolt pattern. That allows mounting virtually everywhere. Drawing at right is available in PDF format or can be viewed here in a larger format.
Total focus travel is 30mm with coarse and fine adjustment. Binocular or trinocular viewing heads for photo and video applications with erect and non-erect image and a low cost monocular head are available. Vertical Koehler illumination with halogen or fiber optic light sources, a range of eyepieces and stands give you lots of options.

Darkfield illumination is supported using Plan Epi Objectives with illumination channel surrounding the core and a vertical Koehler illuminator (MA993) switchable between bright- and darkfield operation. EPI objective shown is part MA989: BD 100X, N.A. 0.90. W.D. 0.37 mm, F.N. 22. 5X, 10X, 20X 50X versions are available as well.
