Ergo-Zoom® 865 – Binocular Microscope on Ball Bearing Base – ESD Safe



Our TKEZ package is the standard model in our Ergo-Zoom® series. Magnification range of this package is 8-65x, and, with all options, is up to 260x (see the below magnification chart). It has detented magnification stops for reliable, standardized inspection. The ergonomically adjustable eyepiece head swivels up and down from 0-35°. Our wide focus, large diameter 10x eyepieces and 1x Auxiliary lens come standard.

Heavy Duty Base

This package features a heavy duty, double ball bearing arm base that provides effortless motion through the range, as well as 20” of horizontal movement. This ESD safe base is built for years of use, without maintenance. The enclosed ball bearing sleeves are specially designed for long use. Articulating armatures are also available for  specialized applications, but are not typically recommended.

Lighting Options

This microscope line is manufactured to use any ESD Safe, Micro-Lite™ illuminator. Our recommended selection is our High Output LV2000 LED Ring Illuminator (-LV2). This array uses very minimal electricity, never has bulbs to replace, and is warrantied for 5 years/50,000 Hours (Pro-rated). It also meets and exceeds the light output of many 150w Halogen fiber optic units on the market today!

Designed with Expansion in Mind

Due to its optical design, this binocular microscope can be converted into a Trinocular model with the addition of the EZ-SPLITTER. This is installed in line of the optics, and is a true Trinocular—no eyepiece loss when in use!
