Oxford Instruments Andor Ltd is a global developer and manufacturer of scientific cameras, microscopy systems and spectrographs for academic, government, and industrial applications.

Oxford Instruments Andor designs, manufactures, and sells scientific imaging equipment, including charge-coupled device (CCD), electron-multiplying CCD (EMCCD), scientific CMOS (sCMOS - an improved Active pixel sensor), and intensified charge-coupled device camera systems, spectroscopy instrumentation, laser-based and laser-free microscopy systems and software.

While studying at Queen's University Belfast, they "used their physics know-how to build a highly sensitive digital camera...as a tool for their laser research."

In December 2004, the company became a PLC when it was listed on the Alternative Investment Market of the London Stock Exchange and raised €6.5 mln euro.

Inouye Solar Telescope (DKIST) on the Haleakala, Hawaii, has produced the highest resolution observations of the Sun's surface ever taken.

[26] In June 2021, the company held a virtual symposium on quantum technology, semiconductors, and power generation,[27] Andor also partnered with Akoya Biosciences to collaborate in Spatial Omics market.

[33] In April 2023, the company launched the ZL41 Wave sCMOS camera platform for physical sciences,[34] followed by MicroPoint 4 photo-stimulation device.
