1) Compact and solid, innovative frame
High rigid but small as XJB600 series is, specially designed for students. The frame with hollow design is lightweight but stable, easy to carry. Pure white body with blue on the both sides, is fresh and vivid.

2) Ergonomics design
According to different interpupillary distances and eyesights of different people, the spacing of binocular tubes can be adjustable from 50mm to 75mm and the left tube with the focusing device, diopter is ±5 adjustable.
Coaxial coarse and fine adjustments on both sides of the frame, are easy to focus by either hand. The tension of coarse knob is adjustable, and the precision of fine knob is 0.002mm. Upper limit design avoids the impact between objective and slide.
