Oxigraf is the leading manufacturer of laser gas sensors. The Oxigraf laser diode oxygen analyzer offers advantages over older technologies such as electrochemical and paramagnetic analysis:

Responds in tenths of a second compared to tens of seconds.
Has no cross sensitivity to other gases.
Corrects automatically for changes in gas pressure or temperature.
Measures quickly over a dynamic range from 100 ppm to 100%.


Oxigraf’s unique technology controls laser diodes to lock on gas absorption lines and reduces laser, electronic, and feedback noise. Our other experience relates to design, assembly, burn-in, and test of chip and surface mount laser diode, optical, and gas cell assemblies. Seven key patents covering the laser gas sensor technology are licensed to Oxigraf.

The Oxigraf team includes about ten employees and two consultants with expertise in optomechanical and electronic engineering, quality systems, and manufacturing. The team is led by Bruce W. McCaul, Ph.D., who has sixteen years of prior experience as CEO in two companies manufacturing laser spectroscopy systems, medical lasers, and medical fiberscopic illumination components. Oxigraf occupies a 4000 square foot facility including equipment to assemble and test diode lasers and oxygen sensors at the rate of 500 per month.

Oxigraf is celebrating twelve years in the business of making laser gas sensors. Recent highlights include:

The Model O2 received clearance for marketing for human use by the FDA under the 510(K) process in 1998.
Oxigraf has performed two Phase I and one Phase II SBIR contracts for the U.S. Air Force and NASA.
Oxigraf has been certified to manufacturing standards under ISO 9001 and EN46001/Annex 2, the European Medical Device Directive.
Oxigraf performed manufacturing and quality engineering services for the ORCA Diagnostic, Inc cardiopulmonary stress test analyzer leading to UL, CSA, and CE approvals in 2000. The ORCA analyzer incorporates an X1004 Oxigraf sensor. Since 2002, Oxigraf has been the exclusive distributor for the ORCA system.
