Meridiem Light Technology: Sufficiently Cool
The ArthroFree design required innovations in signal transmission, power, and light—with minimum thermal by-product. So we created Meridiem®
light technology (MLT): our high-efficiency, low-heat light system.
MLT is backed by Lazurite patents in global jurisdictions, and this market-ready asset indicates opportunities in healthcare, aerospace, and manufacturing.

MLT: The Key Components
We regard MLT as the Hedy Lamarr of light technology: radiant, complicated, and cool. (Lamarr starred in MGM and Paramount films in the 1940s and secured a 1942 patent for a frequency-hopping technology used in telecommunications.)
The key MLT components include:
- A laser.
- Optics that direct a designated spectrum of laser light to a particular location.
- A phosphor core.
The phosphor can be suspended in polymeric and glass-like materials, in a variety of shapes and sizes, for a variety of commercial applications.
Safety and Value, Hand in Hand
Electric lighting constitutes 10% of a hospital’s energy use. Conventional surgical cameras use significant amounts of energy—with enough thermal by-product to require surgical teams to review burn-risk probability ahead of every procedure.
With a maximum temperature of 43°C, ArthroFree poses zero risk of patient burns.
The MLT platform and design are readily scalable. As hospitals and ambulatory surgery centers (ASCs) aim to “go green” and reduce costs, high-efficiency lighting offers a compelling solution.1
