The SF-2TRA stereo microscope is designed primarily for laboratory use, combining precision zoom optics, a robust stand with long-travel rack-and-pinion focus, and a dual-LED illumination system for reflected and transmitted lighting. This microscope is ideal for dissection and general observation of biological specimens, as well as working with sensitive electronic components. Laboratories and educational programs alike will benefit from the touchscreen digital-imaging system which allows for group observation, and avoids eye-fatigue during long-term studies. Electronic repair technicians will also benefit from the 9.7” screen and HDMI output for linking an external monitor or television.
