The architecture
The optics come out of a DVD drive.
An atomic force microscope moves a very fine tip across a surface and
measures how the tip rises and falls. The tip has never been the hard
part. Detecting a deflection of a few nanometres is, and that normally
means optics and actuators machined to order.
CD/DVD and Blu-ray (coming soon) optical pickup units already contain that combination:
lasers, diffraction-limited optics, a high-bandwidth detector and
nano-resolution actuators, manufactured at enormous scale for consumer
drives. Strømlinet Nano designs the microscope around this existing
optical technology.
That is where the price comes from. Not a cheaper microscope.
A different supply chain.
“A feat of ingenuity and technical skill bordering on the improbable.”
