Ⅰ. Product Overview
The ABN‑SZMN series by Abner a zoom stereomicroscope with an innovative structural design. It is equipped with a 0.70‑4.5× continuous‑zoom objective lens (zoom ratio: 6.4:1). When paired with different eyepieces and auxiliary objectives, it can achieve a total magnification ranging from 3.5× to 180×, meeting observation requirements from low‑power panoramic views to high‑power fine details. Its optical components coated with a special film layer ensure a flat image plane and excellent contrast. The 45°‑tilted, 360°‑rotatable viewing head adapts to various operating postures, and the standard 100 mm working distance provides ample space for manipulation. This product is widely used in fields such as the electronics industry, scientific research and teaching, biomedicine and so on. Featuring an innovative structural design, it is more compact and flexible, delivers more comfortable operation and supports broader applications. With a large zoom ratio, high resolution and an extended clear‑view range, it is the preferred choice for inspection and equipment integration in the modern electronics industry.
