Durham Magneto Optics

What Durham Magneto Optics does

Durham Magneto Optics (DMO) is a privately-held scientific instrumentation company founded in 2002 as a spin-off from Durham University's Physics Department. The company designs, manufactures, and sells two families of advanced instruments for nanotechnology research and development: the NanoMOKE3 magneto-optical Kerr effect magnetometers (including a Wafer Mapper variant for large-area semiconductor characterization) and the MicroWriter ML family of maskless direct-write laser lithography machines (spanning four tiers from the entry-level Baby to the flagship Pro with 0.4μm resolution). The underlying technologies combine direct-write laser lithography, video-rate Kerr microscopy, dual-wavelength light sources, XY interferometer-controlled stages, and integrated optical profilometry to enable rapid prototyping, mask-free photolithography, and ultra-high sensitivity magnetic characterization of thin films, nanostructures, MRAM devices, spintronic components, and 2D materials.

DMO operates from offices in Cambridge, UK (headquarters) and Raleigh-Durham, USA (North American subsidiary), with a research-focused team of 15 employees led by founder Professor Russell Cowburn as CEO. The company sells capital equipment on a quote-based, one-time perpetual license model, with prices structured across product tiers from entry-level desktop systems to flagship configurations with cryostats and high-field magnets. Revenue is generated through initial system sales plus aftermarket upgrades (e.g., Mesa to Pro conversions) and post-sales servicing. The go-to-market combines direct sales in the UK and USA with a global channel partner network managed by Quantum Design, covering 40+ countries across Europe, Asia Pacific, South America, the Middle East, and Africa. DMO has deployed over 200 machines across 6 continents since 2002, serving academic research laboratories, government research institutions, and industrial R&D customers in semiconductor, spintronics, MEMS, and advanced materials development.

Core offering

Durham Magneto Optics designs, manufactures, and sells advanced scientific instruments for nanotechnology research. The company offers two product families: the NanoMOKE3 magneto-optical Kerr effect magnetometers for ultra-high sensitivity magnetic characterization and domain imaging of magnetic thin films and nanostructures, and the MicroWriter ML3 family of maskless direct-write laser lithography machines for rapid photoresist patterning without physical masks. These capital instruments serve academic, government, and industrial research laboratories working in nanomagnetism, spintronics, MRAM, MEMS/NEMS, microfluidics, and materials science.

Product overview

Durham Magneto Optics offers two families of scientific instruments for nanotechnology research: NanoMOKE3 magnetometers and MicroWriter ML lithography machines. The NanoMOKE3 family includes the base NanoMOKE3 (Kerr effect magnetometer-microscope) and the NanoMOKE3 Wafer Mapper variant for large-area wafer characterization. The MicroWriter ML family includes four tiers of direct-write optical lithography machines: MicroWriter ML3 Pro (flagship with largest 195mm writing area and finest 0.4μm resolution), MicroWriter ML3 Mesa (mid-range), MicroWriter ML3 Baby Plus (compact with automated features), and MicroWriter ML3 Baby (entry-level desktop). The products serve semiconductor, spintronics, MEMS, and materials science research markets worldwide.
