(Z850) Stereo Zoom Microscope with Boom Stand

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.

Ball Bearing Boom Stand

This boom stand provides a smoothly operating, non-rotating motion that is ideal for TEV-700 (oocyte) applications, as well as for all applications requiring a dissecting scope. (Trinocular viewing head shown.)

Standard Boom Stand

This boom stand features safety tracks on the horizontal arm and Delrin^®inserts in the focus block to ensure smooth, precise movements.
