The Concerto

Share this on social media:

Power Technology has developed the 442nm solid state HeCd replacement laser, the Concerto. This unit is able to overcome limits faced by traditional HeCd lasers and laser diodes.

The technology makes it possible to deliver up to 150mW of actively stabilised single-frequency laser light with a spectral bandwidth of less than 5MHz. The Concerto also delivers a coherence length of greater than 100m. This instrument is suitable for applications in holography, security printing, spectroscopy, thin film analysis, flow visualisation, optical data storage and semiconductor inspection.

A key feature of the Concerto is its MTBF value of greater than 12,000 hours. In addition, this laser has an initial capital purchase cost similar to a gas laser but does not require re-tubing.
