Mounting a Camera
A camera is not included with the microscope, but WPI carries a variety of cameras if
one is necessary. In the example shown below the COLCAM closed circuit television
(CCTV) camera is used. This camera can be connected to a television. Digital cameras are
available that will connect with a computer or laptop.
When mounting a camera, the WPI camera adapter package (#
503097
) may be
purchased for added flexibility. This package includes an eyepiece lens, a 30mm adapter
and a female C-mount. With this kit, a camera can be mounted to the microscope in one
of a variety of ways, as shown on the next few pages. Choose the option that best meets
your needs.
