Power Technology (Little Rock, AR) has announced the availability of PNF Series green wavelength spectrum lasers suitable for surgical and X-ray alignment applications on dark or pigmented skin. Green lasers are much more visible to the human eye against dark or pigmented skin than traditional red wavelength surgical lasers. In fact, PNF green wavelength line-generator lasers are much easier to identify under the extremely bright light conditions of the operating room. The Green PNF Series can deliver an output power of either 20mW or 45mW with a wavelength of 515nm. Additional design features include uniform intensity (non-Gaussian) line generators, unique Variable Focus Technology, high wavelength stability, high optical power stability, and CW or optional digital/analog modulation >500kHz.
