The SM-3B is a heavy-duty, highly-flexible microscope designed for biological and industrial applications. This model is especially popular in the QC, dental, repair and engraving industries thanks to its ease-of-use and reliability. With its wide zoom range and single-arm boom-stand, this model will become an indispensable instrument in any workshop or lab.
Optics
The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles.
Ocular Adjustment
Dual ocular diopters can be adjusted to maintain consistent focus, greatly improving productivity. Rotating interpupillary adjusters simplify the process of aligning the eyepieces for each user.
Single-arm Boom-Stand
The multi-pivoting stand provides a stable, flexible support system, ideal for hands-on work. The single-arm design provides heavy-duty support in a simple form. The head can be turned 360°, the focus-block can swing in either direction, and the lateral arm can rotate and swing to position the head at virtually any angle. The heavy, steel base ensures the stability of the microscope, even when laden with attachments.
Additional Items
This package includes a powerful 30W LED illuminator with a fiber-optic gooseneck. The energy-efficient light-source projects bright, daylight-balanced light which is channeled through a 22" gooseneck fiber-optic light-guide. This allows you to project light from virtually any angle, targeting specific details of the object being viewed. The flexible, heavy-duty metal-sheathed guides will hold up to heavy use in your workshop, factory, or lab without worry of crimping or breaking. The light-source is equipped with an active cooling system which is much quieter than comparable incandescent illuminators due to the lower heat level generated by LEDs.
