Ibsen Photonics, a leading supplier of holographic Phase masks, transmission diffraction gratings and optical spectrometer modules based on diffraction gratings, today announced that it has been granted United States Patent # 6,978,062, titled "Wavelength Division Multiplexed Device".
The technology is based on using multiple transmission gratings to provide high dispersion, while at the same time taking advantage of the beam-folding properties of transmission gratings to create compact module designs.
"Our optical module products - for example FBG Sensor System Interrogators and DWDM Optical Channel Monitors are uniquely high performance and compact simultaneously" says Bjarke Rose, Spectrometer Module Product manager at Ibsen, and adds: "our internally produced fused silica transmission gratings are instrumental as they exhibit exceptional angular tolerance."
Torben Jacobsen, President and CEO comments: "This is a prime example of how our strategy of combining world-leading grating technology with innovative optical design capabilities allows us to offer optical spectrometer modules with great performance on points that by traditional thinking required trade-offs."
