AmScope - 3.5X-45X Simul-Focal Stereo Lockable Zoom Microscope on Dual Arm Boom Stand - SM-4NTPX

This is a highly-flexible stereo microscope, designed for workshops and industrial inspection. Featuring a simul-focal head, the photo port can be used concurrent with both eyepieces, allowing you to have an active imaging system without losing use of one of the eyepieces. The objective optics offer a contiuous zoom-range from 0.7 to 4.5X, providing 7-45X magnification with the 10X high-eyepoint, super-widefield eyepieces. The addition of a 0.5X Barlow lens reduces the magnification range to 3.5-22.5X for a larger field of view, as well as a larger working distance. This model also provides a zoom lock to maintain a fixed magnification for calibrated measurement applications. The nosecone provides a built-in ring-light adapter, as well as inner threading for auxiliary lenses and other attachments.

The multi-pivoting, double-arm stand provides a stable, flexible support system, ideal for hands-on work. Use of a drop-down column allows the head to be positioned at virtually any angle. Especially convenient for quality-control inspections, teaching demonstrations, and many other industry applications, your colleagues or students can simultaneously view clear images shown through the trinocular port while you work through the eyepieces.
