H-Bar Instruments is a company producing and testing scientific instruments.
The reduced Planck constant (h-Bar) is a fundamental physical constant of foundational importance in quantum mechanics; a photon's energy is equal to its frequency multiplied by the Planck constant. The H-Bar character is equal to the Planck constant divided by 2π.

h-Bar Instruments deals with atomic imaging and ultra-cold temperatures; it helps taking high resolution images of cold atomic crystals and will revolutionize the world of imaging at atomic sizes.
The H-Bar Instruments logo shape recalls the atomic lattice perceptible at microscopic lengths; among the atomic connections, an h-bar symbol is embedded.
