Rapid and Reliable Calibration of Laser Beam Deflection System for Microcantilever-Based Sensor Setups

Cantilever array-based sensor devices widely utilise the laser-based optical deflection method for measuring static cantilever deflections mostly with home-built devices with individual geometries. In contrast to scanning probe microscopes, cantilever array devices have no additional positioning dev...
