Product Description

Meiji Techno’s BM Series Long Arm Stereo Microscopes are high quality industrial and healthcare quality stereo microscopes mounted on a 255mm horizontal inclinable arm supported by a 300mm vertical post and heavy cast base. The integral illuminators on BM Models feature a three lens condenser system fitted into the binocular body and a 6 volt power supply inside the base. The paired interchangeable parfocal objectives are mounted on a dovetail slide and each unit is supplied with a plastic dust cover, grounded power cord and fitted Styrofoam packing.

BM Straight-Viewing Stereo Models BM-1 and BM-2

The BM straight viewing stereo microscope incorporates a focusing unit and is provided with a rear-mounting hole that enables it to be fitted to a suitable SPIGOT, such as the SWIVBM, an inclinable mount from the UHM series stand system.

The BM microscope includes a pair of interchangeable SWF10X super wide field eyepieces and two sets of slide-in objectives 1X and 2X, giving 10X and 20X magnification. A total magnification range of 5X to 70X is achievable with optional eyepieces and objective sets. The interpupillary distance is adjustable from 45mm to 80mm and the left-hand eyetube is focusable.

The BM head is most frequently used with the strip fluorescent lighting system for maximum evenness of illumination or with the FLEXISPOT where more directional intense illumination is required.

Overall, the BM microscope is suitable for high performance but low complexity OEM viewing systems where straight path viewing is required. It is also and ideal instrument for inspection and re-work systems for SMD applications.
