Framed Print of NBS-1, NIST Atomic Clock
In 1952, NIST completed the first accurate measurement of the frequency of the cesium clock resonance. The apparatus for this measurement is named NBS-1. In 1955, the National Physical Laboratory in England built the first cesium-beam clock used as a calibration source. In 1959, the NBS-1 went into regular service as NIST's primary frequency standard. An atomic clock is a clock device that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS. © NIST / Science Source

Prints are glazed with lightweight, shatterproof, optical clarity acrylic (providing the same general protection from the environment as glass). The back is stapled hardboard with a sawtooth hanger attached. Note: measurements provided are estimated outer dimensions, which include both the image and the frame. While we aim to keep sizing consistent, exact dimensions may vary slightly due to differences in print size or production requirements, which may result in a variation in the overall size (up to approximately 2.5cm (1"))
These are individually made so all sizes are approximate
Estimated Image Size (if not cropped) is 24.4cm x 18.9cm (9.6" x 7.4")
Estimated Product Size is 36cm x 31cm (14.2" x 12.2")
