Inexpensive digital imaging?

The capture of digital images through the use of a frame grabber provides tremendous advantages to scanning electron microscopy. Accessory frame gabbers can range in price from very inexpensive to several thousand dollars. This work investigates the application of one inexpensive ''consumer product'' frame grabber which has recently been introduced to scanning electron microscope (SEM) imaging. The application of this frame grabber to the SEM as a low-cost, entry-level digital imaging tool is explored, and its performance is compared with a more expensive system.
