The Hitachi HT7500 transmission electron microscope is equipped with a phosphor screen and an AMT NanoSprint12: 12 Megapixel CMOS TEM digital camera. The system is designed for the observation and evaluation of specimens using the electron beam maximum acceleration of 120 KV. Wide fields of magnifications are available both within the low and high magnification functions. Focal distance is selectively usable between high-resolution and high-contrast applications by means of a double-gap objective lens. The main PC integrally controls the TEM main unit and digital AMT camera. A secondary PC is attached to allow users to track and assemble serial images via image software. The H-7500 was Hitachi’s first pc based TEM sold in the USA. The H-7500 has a phosphor screen and can take pictures with a film or use a digital camera.
The HT7700 is a state-of-the-art transmission electron microscope. It has Hitachi’s “Dual-Mode” objective lens that helps to achieve superior low magnification, high-contrast as well as high magnification, and high-resolution imaging. All image acquisition is digital and there are options that can be used to readily examine and align serial sections. It is equipped with an AMT XR41-B 2K-by-2K digital camera. The HT7700 improved upon the features of the H-7500 and is the 4th generation of PC-based TEMs that uses only a digital camera to obtain images.
