The XSZ-W zoom tube is a versatile accessory that is primarily designed for use with a CCD camera. It allows the user to "transfer" images onto a monitor for greater emphasis and detail, while allowing others to view the images, with its wide working distance capability. This high-resolution system accommodates nearly all-specific requirements for magnification and field of view. It can be utilized in education, industry, R&D, science, and a wide variety of other applications that require clear and precise magnification.
The XSZ-W single zoom tube is the latest design in high quality optical equipment. It may be used in any of our stands and fits on every arm. Designed as a modular system, with all metal construction. A number of auxiliary lenses and photo eyepieces may also be used to suit nearly every application. The XSZ-W combines user friendliness with versatility, and provides the user with ease of handling to gain optimum results.

A variety of Stands and Illuminations are available, the Photo Eyepiece outside diameter 33mm, we provide a Donut to hold the Photo Eyepiece and the scope body, this allows it to be put on a Stand with 83mm ring holder likes Universal Arm or Focusing Mount. When a Ring Light is used, a Ring Adapter is fixed on a scope body for holding the Ring Light.
