Widefield WHSZ10X-H/22
Optical System
Greenough stereo zoom
- Greenough stereo optics for a natural three-dimensional image
- Continuous 0.8× to 4× zoom with a 5:1 ratio (8× to 40× with 10× eyepieces)
- Constant 110 mm working distance across the full zoom range
- Dual horizontal zoom knobs with adjustable high and low magnification stops
- 45° binocular tube with 52 to 76 mm interpupillary adjustment
- Helicoid eyepieces accept 24 mm micrometer disks for measurement
- Ball-guided rack-and-pinion focus with tension adjustment and 120 mm stroke
- M48 thread accepts optional auxiliary objectives from 0.5× to 2×
- Reversible white/black 100 mm stage plate
- Compatible with LED transmitted light, light-guide, and ring-light illumination
- ESD-protected optics for electronics and sensitive-component work
The Olympus SZ51 Stereo Microscope pairs Greenough-type stereo optics with a continuously variable 0.8x to 4x zoom, giving a standard magnification range of 8x to 40x with the included 10x eyepieces and a working distance of 110 mm that stays constant as magnification changes. Horizontal zoom knobs on both sides of the body, adjustable high and low magnification stops, and a 45° binocular tube with 52 to 76 mm interpupillary adjustment keep operation comfortable and repeatable for extended dissection, assembly, or inspection work. Focus runs on a ball-guided rack-and-pinion with adjustable knob tension over a 120 mm stroke, so the body settles precisely and holds position across repeated sessions.
The SZ51 mounts on the SZ2-ST standard stand with a 100 mm reversible stage plate (milky white on one side, black on the other) and accepts optional transmitted LED illumination, light-guide systems, and ring lights. An M48 thread at the base of the body accepts optional auxiliary objectives from 0.5x to 2x, extending the usable range from 4x to 80x and shifting the working distance anywhere from 38 mm to 200 mm to suit the task at hand. Helicoid eyepieces accept 24 mm micrometer disks for direct measurement, and a C-mount camera port with built-in 0.5x lens is available on compatible configurations. ESD-protected optics and a 5x zoom ratio make the SZ51 a straightforward, dependable stereo platform for teaching, quality control, and routine laboratory use.
The Olympus SZ51 Stereo Microscope includes:
- Widefield WHSZ10X-H/22 Eyepieces
- LED Illuminator
- Operator's Manual
- Full 180 Day Parts and Labor Warranty
