Product Description

The Aven 26800B-369 stereo zoom microscope has a SPZT-50 body, trinocular viewing heads, magnification abilities of 6.7X to 50X, a zoom ratio of 7.6:1, a fiber-optic illuminator with ring light, and comes with a digital color camera with image capture and measurement software. This microscope enhances object or image resolution with a stereo optical system that produces three-dimensional images. It is commonly used inspection, research, and for educational applications.

This microscope features trinocular viewing heads set at a 45-degree angle to ease eye strain and provide a more comprehensive view, and a third head to connect to an external monitor for an alternative viewing option. It has a fiber-optic illuminator with ring light, for a uniform illumination over a selected field of view. It includes a multi-feature, 3MP USB 2.0 digital color camera with image capture and measurement software. Software is compatible with Windows Vista 7 and PC computers. It has a dual-arm ball bearing boom stand with mounting post. The post has a tilt feature for a SCW-PA focus mount (included). Its design offers gliding movement for inspection applications where magnification adjustment and the ability to move across a specimen are important. It has a 10X widefield eyepiece magnification with field number (FN) of 20. Its objective lenses have 0.67X to 5.0X zoom magnification. Optical components are coated multiple times, and corrected for chromatic and spherical aberration. The microscope has a tension control pin on the focus adjustment wheel. It comes with a safety clamp, a dust cover, a 0.5X auxiliary lens, a 3MP USB 2.0 color digital camera, a C-mount camera adapter, IsListen image capture and measurement software, and instructions. The 26800B-369 is compatible with Windows Vista, and 7, PC’s and IsListen and ez Measure software for Mac computers.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying viewing abilities. A trinocular eyepiece is used to output digital images or video to an internal or external device such as a camera or monitor. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also use LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.

Aven manufactures optical inspection tools, precision tools, and bench accessories for industrial, scientific, and research applications. The company was founded in 1983 and is headquartered in Ann Arbor, MI.
