The OC White TKDEZT-850 series are trinocular microscopes with a 2 megapixel digital camera. Part of the Ergo Zoom microscope family, these feature the EZ-850 body, with a wide range of possible working distances and magnifications. This system is also presented in a modular format, enabling users to customize the product for their specific application. Many different stands and illumination sources are available, which are quickly and easily changed.
 
The TKDEZT-850 includes a 2 megapixel digital camera. This attaches to the trinocular port of the microscope and makes research documentation as easy as possible. The camera comes with the OC White Image Acquisition and Measurement Software Suite, which is used for image capture, video capture, 13 different measurement functions, and much more.
 
The TKDEZT-850 has a zoom range of 0.8x to 5x, and is compatible with several styles of eyepiece and objective. Available eyepieces come in 10x, 15x and 20x magnification, with objectives ranging from 0.5x to 2x. This creates a high level of versatility, as users can create substantial changes in working distance and magnification by simply changing one part. Working distance refers to the amount of space between your specimen and the microscope’s objective – increases in this number indicate a larger amount of room for the user to operate. Depending on the configuration, the TKDEZT-850 has a working distance of 32.5 to 200mm, and an overall magnification from 4x to 200x. Please see the chart below for more information.
 
Several illumination sources are compatible with this system. OC White manufactures a variety of ring lights, with several sizes, color temperatures, as well as ultraviolet models. Multiple fiber optic sources are also available with many termination styles, including in an annular ring, and adjustable goosenecks. For users requiring different illumination sources, owning more than one light is not an issue, as they are very easy to change.
 
The TKDEZT-850 is available with two types of eyepiece tubes – fixed and adjustable. Fixed tubes are positioned at a 20 degree angle, while adjustable models can be moved from 0 to 35 degrees. Fixed tubes are also denoted in their part number by an "FH". For example, TKDEZT-850 versus TKDEZT-850-FH.
