PM240 Zoom Trinocular Stereo Microscope 8X-80X on Track Stand w/Common Main ObjectiveCMO

PM240 Series Zoom Trinocular Stereo Microscope 8X-80X Magnification on Track Stand with Common Main ObjectiveCMO. Our PM240 line of stereo microscopes takes advantage of the common-main-objective CMO optical design. Different from the more traditional models which use the Greenough design characterized by tilted objective lenses, CMO microscopes use a single objective lens which focuses light into two parallel optical paths. This results in some major advantages which include the removal of keystone distortion, and the ability to introduce intermediary optical systems without loss of image integrity. The modular design of the PM series allows for multiple configurations in which components can be added or replaced. Standard Viewing Head The standard viewing head keeps things simple. Elongated ocular tubes are mounted at a 20° angle, and allow viewing from a comfortable distance. Alignment with the eyes is done by using a sliding interpupillary adjuster. The tubes lack integrated diopters, so dioptric adjustments can be made by using focusable eyepieces when needed. Optics The zoom module provides a large 10:1 zoom range covering magnifications from 0.8X-8X. When used with the standard 1X objective and 10X eyepieces, the microscope produces images with stunning clarity at 8X-80X total magnification. Magnifications and Working-Distances Objective Eyepiece Standard 78mm WD 10X 8X-80X Infinity Optics This microscope uses an infinity-corrected optical system which allows for a modular design in which accessories can be added without affecting magnification or image quality. Such accessories include photo ports and coaxial illumination systems. Keystoning By using a single objective lens and parallel optical paths, the CMO design avoids a type of distortion seen in other stereo microscopes called the keystone effect. Tilted objective lenses cause the independent images to be distorted in a manner where one side is larger than the other. This also causes gradual changes in focus and reduced depth-of-field. CMO microscopes do not suffer from this distortion, allowing for improved resolution and depth. Dedicated Photo Port This model includes an inline photo-port module which can be installed between the viewing head and zoom module. This adds a dedicated port for attaching a camera, avoiding the need to use one of the ocular tubes. The side-arm-style port uses a 23mm tube to accommodate a wide range of cameras with reduction lenses. When the port is switche
