(Z850) Zoom Stereo Microscope Series

Product Summary

High Performance Optics, Unsurpassed Ergonomics

 

The Z850 Series is a versatile, high performance, ergonomically designed zoom stereo microscope ruggedly built to withstand years of heavy usage. With a zoom ratio of 6.3:1 the Z850 provides superior optical performance at an affordable price.

Key features include:

  • Binocular or trinocular viewing heads are inclined 45º and can rotate 360º
  • A best-in-class 8x-50x magnification range with click-stops at 10x, 20x, 30x, 40x and 50x 
  • 115 mm working distance allows easy access to specimens
  • WF 10x,/22 mm field of view eyepiece 
  • Airtight assembly prevents contamination from dust, water, oil 
  • Z850 stereo bodies are made of anti-electrostatic materials 
  • An anti-mold design, in addition to being air tight, allows the Z850 to be used in areas of high heat and humidity

Microscope viewing heads

All microscope viewing heads (binocular or trinocular) can accept eyepieces and objectives. Generally speaking, eyepieces establish the magnification range and objective establish the resolution and working distance of the microscope. (The objective also affects the magnification range, but it's easier to consider this separately.)

Eyepieces

Eyepiece selection is required and 10x is considered standard. The base magnification range of the viewing head is 0.8-5x , and the 10x objectives increases this range to 8-50x. (The 20x eyepieces will increase the magnification range to 16-100x.)

Objectives

Z850 microscope heads do not require separate objectives and the native design provides 1.0x magnification at a working distance of 115 mm. Auxiliary objectives of 0.5x, 0.7x, and 2.0x are available, with the 2.0x objective providing the greatest increase in resolving power at the expense of of a shorter working distance of 43 mm. 

The 2.0x objective doubles the microscope's resolution by reducing the area of the visual field. While providing greater resolution, this reduced visual field has the side effect of increasing the magnification since a smaller visual field can look like a zoom. However, the resolving power (ie, the detail you can see) will be greater with a 2.0x objective at 1x zoom over a 1.0x objective at 2x zoom) .

What's included

  • Microscopes sold with stands include 10x eyepieces.
    Additional eyepieces of 15x and 20x are available.
     
  • Viewing heads sold separately require the purchase of eyepieces.
     
  • All viewing heads are 1.0x objective native.
    Optional 0.5x, 0.7x and 2.0x objectives are available.

View the bottom table in Specifications to see the effect of objectives and eyepieces on working distance, zoom range, and the visual field.


Microscopes with stands

Plain Focusing Stand-Binocular

The Plain Focusing Stand’s thin design helps keep sample positions low resulting in increased user comfort. The focus mount is easily removable and can be positioned at two different points on the dovetail to offer maximum flexibility when working with small or large size samples.

Zoom Stereo Microscope Series (Z850)

Plain Focusing Stand-Trinocular

The Plain Focusing Stand’s thin design helps keep sample positions low resulting in increased user comfort. The focus mount is easily removable and can be positioned at two different points on the dovetail to offer maximum flexibility when working with small or large size samples. The trinocular Z850 is pictured with an optional MicrometricsTM CCD camera and C-mount adapter.

Zoom Stereo Microscope Series (Z850)

LED Illuminator Stand-Binocular

Simultaneous variable reflected and transmitted LED illumination can be utilized on this stand. The compact, thin design of the base allows users to keep sample positions low and maintains easy accessibility to the variable light controls. The reflected LED illuminator is powered by a 12 volt, 2 watt LED system and the transmitted LED illuminator by a 12 volt, 4 watt LED system. Both light sources are variable and controlled by a universal power supply (110–240V).

Zoom Stereo Microscope Series (Z850)

Boom Stand-Binocular

A variety of stands are available for the inspection of large size specimens. The boom stand features safety tracks on the horizontal arm and Delrin® inserts in the focus block to ensure smooth, precise movements.

Zoom Stereo Microscope Series (Z850)

Ball Bearing Boom Stand-Trinocular

For users seeking precise, stable movements the ball bearing boomstand is the recommended choice. Sturdy and ruggedly built, the ball bearing boom stand is ideal for observation applications where magnification adjustment and the ability to move across a sample are important considerations. The trinocular Z850 is pictured with an optional MicrometricsTM CCD camera and C-mount adapter.

Zoom Stereo Microscope Series (Z850)

Articulating Swing Arm Stand-Binocular

Designed for maximum freedom and flexibility this stand will deliver the adjustability you need. Ideal for the inspection of specimens that require a lot of movement or to scan a large sample area, the articulating arm can be easily adjusted into hard to reach positions and moved easily out of the way.
