The Higher the Magnification - The More Detail You'll See

Magnification can represent combinations of lenses including objective, ocular, and auxiliary lenses. The magnification ranges described here may include these combinations.

Compound Microscopes may include additional eyepieces (ocular lenses) to expand the total magnification range.

Stereo and other Inspection Microscopes may include additional eyepieces and auxiliary lenses including Barlow lenses to expand the total magnification range.

Camera Types

Various types of cameras are available. Cameras intended to be used with computers will use USB, wi-fi, or LAN to connect to the computer, and typically include specialized software. Cameras with HDMI, VGA, or analog video interfaces can be attached directly to a compatible display device such as a monitor or television, and do not require a computer to operate.

Camera Pixels

Also referred to as camera resolution, the number of pixels represents the maximum size of images which can be displayed or recorded by a camera. The value is displayed using MP (megapixels).
