NIH awards Vixar Phase II SBIR grant for red VCSEL laser scanning in computed radiography

Vixar of Plymouth, MN, USA, which designs and manufactures vertical-cavity surface-emitting laser (VCSEL) products operating at wavelength of 650–900nm, has been awarded a Phase II Small Business Innovative Research (SBIR) grant ‘Novel Laser Scanning Technology for Computed Radiography’ by the US National Institutes of Health (NIH) to develop a large red VCSEL array assembly for the readout of images in computed radiography systems. Vixar will collaborate with manufacturers of computed radiography systems to evaluate the potential of the technology.

“Reducing the size, increasing the resolution and reliability of computer radiography have been key drivers for potential customers interested in the technology,” comments Bill Hogan, Vixar’s director product development.

Vixar is also pursuing wafer-scale packaging approaches for combining laser arrays with cost-effective packaging and lensing solutions.

VCSEL-based components and subassemblies are increasingly being used for sensor and device applications in the biomedical, industrial, office product, military, automotive and consumer industries, says Vixar. Benefits include miniaturized cost-effective platforms, performance equal or better to edge-emitting lasers, and the lowest available power consumption, the firm adds.
