An excellent lower-magnification solution with wide, three dimensional stereoscopic vision, the Swift SM95-90HF Microscope is a great solution for educational facilities.
This binocular microscope has 10x and 30x effective magnification, with a reversed nosepiece design to make it easier for students to access the observation slides. The entire binocular assembly rotates 360° so that the view can quickly be shared amongst observers. Unlike upon other models, the focus point does not change when the interpupillary distance (the length between eyepieces) is adjusted for new users.
As an improvement of a series that proved to be their most popular student's binocular microscope (the SM80), the SM95-90HF is clearly made for schools-many "student-proof" features to enhance operation longevity are present. Critical parts are locked on, eliminating concern for theft or tampering. A slip clutch system helps keep the gearing protected from an overly-aggressive user. And remember, Swift's been supplying microscopes to educational facilities for decades-they're dedicated to service after the sale whenever called upon, which can be awfully important in a pinch.
The SM95-90HF features a dual lighting source system. Above the specimen is a halogen lighting beam with a dimmer switch and a user-controlled incidence angle. Underneath the specimen is Swift's 'Ultra Lite' fluorescent illumination, and together you can alter intensity and ratio enough to eliminate the need for a condenser diaphragm-one less thing for a novice to damage.
