Navitar grants Hoffman Modulation Contrast trademark license to Carl Zeiss

Nov. 3, 2011
Rochester, NY--Navitar has licensed its Hoffman Modulation Contrast (HMC) microscopy trademark to Carl Zeiss MicroImaging GmbH.

Rochester, NY--Navitar, producer of high‐magnification imaging optics, precision laser optical assemblies, and custom microscopy systems for automated medical and biophotonics processes including flow cytometry, live cell analysis, fluorescence imaging, DNA sequencing, in vitro fertilization, stem cell imaging, and two‐photon microscopy, has licensed its Hoffman Modulation Contrast (HMC) trademark to Carl Zeiss MicroImaging GmbH (Jena, Germany). The contract terms state that Carl Zeiss will manufacture objectives, modulators, slit apertures, and condensers using the HMC technology, and distribute and sell them under the iHMC name.

According to Navitar, Hoffman Modulation Contrast technology--originally developed and patented by Dr. Robert Hoffman back in 1975--has become the world’s most widely used light microscopy contrast method for viewing colorless and transparent biological specimens. Navitar is the sole owner of the HMC trademark due to its recent acquisition of the assets of Modulation Optics (Glen Cove, NY). Prior to the acquisition by Navitar, Modulation Optics partnered with Research Instruments Limited (RI; Falmouth, England) to combine the imaging capabilities of HMC technology with RI’s instruments for Intracytoplasmic Morphologically-selected Sperm Injection (IMSI) in the development of the optics for RI IMSI.

"Zeiss’ licensing of the Hoffman Modulation Contrast mark reinforces the importance of this brand to the fields of biotechnology and medical research," says Julian Goldstein, co-president of Navitar. "Navitar is pleased to partner with such a major player in the world of optics." Carl Zeiss MicroImaging is a subsidiary of Carl Zeiss AG that manufactures microscope systems for biomedical research and the healthcare and high-tech sectors.
