AmScope PM230 Series Zoom Trinocular Stereo Microscope 8X-80X Magnification on Track Stand with Common Main Objective(CMO), Adjustable Head + 20MP USB3.0 Camera

Our PM230 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. Adjustable Viewing Head The adjustable viewing head provides a new level of comfort. The most notable advantage is the ability to tilt the ocular assembly from 0°-30°, accommodating users of varying height, or working from sitting or standing positions. Additionally, the ocular tubes use a rotating design to adjust the interpupillary spacing and height over a large range. 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 C-mount interface with 0.5X built-in reduction, making it suitable for cameras with 1/2” format sensors. When the port is switched open, it shares light with the viewing head, allowing use of all ports simultaneously. Closing the port allows all light to be passed through to the eyepieces for maximum brightness. Support and Illumination The dual-illumination stand provides a turnkey solution for biological and industrial applications. LEDs are used for the overhead and sub-stage light-sources, providing bright, low-heat illumination. Reflected and transmitted illumination allows for a wide gamut of specimens to be viewed. The track-style stand uses rack-and-pinion movement and large control-knobs for coarse adjusting focus. The stage uses extra-large 140mm circular plates for placing specimens. A transparent glass plate is included for use with the sub-stage transmitted illumination, allowing for a range of biological or other translucent specimens. A reversible black-white plate can be used when transmitted light is not needed, providing two options for enhancing specimen-contrast. Digital Imaging Monitor and capture photos and videos with the included 20.0MP USB3.0 camera. The C-mount camera is specially designed for use with microscopes, allowing you to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. The USB 3.0 connection provides greater bandwidth for faster frame-rates. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.
