Compact Stereo with High-Quality Optics

Greenough Optical System

The 10-degree angle of convergence in the Greenough optical system secures excellent image flatness with large depth of field. The careful selection of lens surface coatings and glass materials in the entire optical system makes it possible to observe and document specimens in their original, authentic colors. The V-shape optical path achieves a slim zoom body - suitable for integration into other equipment or standalone use.

Wide Zoom Ratio

The SZ61’s magnification range extends from 6.7x to 45x (using 10x eyepieces), with a wide zoom ratio of 6.7:1, enabling smooth, macro-to-micro zooming that speeds routine workflows. The SZ51 provides the magnification rage of 8x to 40x (using 10x eyepieces), with a wide zoom ratio of 5:1.

Viewing

The suitable inward angle allows just the right combination of high level flatness and depth of focus for 3D viewing. Even a specimen with significant depth can be brought into focus from top to bottom for faster inspection.

LED Illumination

The universal reflected/transmitted light LED illumination stand brings together all the advantages of LED technology. The flat, high-brightness LEDs allow successful integration of transmitted illumination into a very slim base, which in turn facilitates easy specimen access and manipulation.

Electrostatic Discharge Protection

The main body and major accessories can quickly eliminate static electricity with the use of antistatic materials and coatings. This prevents a specimen under observation from electrostatic damage.

Choice of High-Performance Bodies

The SZ61 and SZ51 zoom bodies provides 2 different magnification ranges, and each one is ergonomically designed with a 45-degree inclination tube as the standard model. For special applications where the zoom body has to be tilted of use with other equipment of mounting on a universal stand, the built-in models with 60-degree inclination tube are available. For documentation purpose, a trinocular model is available for the quick and easy attachment of digital cameras.

Choice of Suitable Contrast and Observation Method

SZX2-ILLTQ/SZX2-ILLTS

With a slim 41.5 mm design, that is approximately half the thickness of previous halogen transmitted light illumination bases, new LED transmitted light illumination bases have a lower height to enable a low eyepoint and easy access to base-mounted samples during observation and operation.

Cartridges for SZX2-ILLTQ/SZX2-ILLTS

New LED illumination base SZX2-ILLTQ four position turret (SZX2-ILLTS one position) enables the user to choose cartridges and to switch from brightfield (Standard/High/Low), oblique (Standard/High/Low), darkfield, polarized illumination and shutter with a simple turn. This makes the SZ61/51 a flexible microscope for various samples and observation tasks.
