The CRESTA XS-50 Plus Binocular Microscope is a professional laboratory microscope featuring a 30° inclined, 360° rotatable Siedentopf head, semi-plan achromatic optics, precision coaxial focusing and a ball-bearing-driven mechanical X-Y stage. Its 40X–1000X optical configuration and adjustable LED illumination make it suitable for medical, educational, research and laboratory microscopy.

3. Detailed Product Description

Product Overview

The CRESTA XS-50 Plus is a binocular compound microscope designed for professional laboratory and research applications. Its rigid single-mould construction provides a stable platform, while the Siedentopf viewing head offers a 30° inclined viewing position and 360° rotation.

The microscope uses a WF 10X/18 mm eyepiece with 4X, 10X, 40X S/L and 100X S/L Semi-Plan Achromatic objectives, providing a 40X–1000X magnification range.

A reversed inward quadruple ball-bearing nosepiece provides positive click-stop objective positioning. The coaxial coarse and fine focusing mechanism has 0.002 mm graduation, while the ball-bearing-driven mechanical stage provides X-Y slide movement.

A movable Abbe condenser with NA 1.25, iris diaphragm and swing-out filter holder provides control over specimen illumination. Built-in LED illumination with intensity control provides adjustable lighting for routine microscopy.
