Building A Do-It-Yourself Atomic Force Microscope
 
By James F. MacKay, Mad City Labs

Atomic force microscopes (AFMs) are versatile tools for characterizing surfaces down to the subnanometer scale. Researchers can build their own AFMs for as little as $30,000 using off-the-shelf components such as nanopositioning stages.

How Quantum Cryptography Works

With ever-increasing importance in data exchange and data security, cryptography, or the encoding of a message, becomes essential. A key must also be exchanged in order for the message to be decrypted. In order to protect the key exchange from being intercepted, quantum cryptography must be utilized.

High-Speed Science-Grade MWIR Camera: FLIR X8500sc

FLIR offers the X8500sc as its new high-sensitivity, high-speed MWIR camera for science and R&D applications. With 1280 x 1024 resolution, fast frame rates, and RAM/SSD recording, this camera allows for full imaging of the scene and stop motion on high-speed events both in the lab or on the test range.
