The B4 series of lasers is an extension of the tried and tested G4 product range. The blue wavelength is set at 473nm CW, opening up a new and varied spectrum of applications. These single longitudinal mode systems maintain high end specifications in beam quality and noise. The physical size of the laser together with an OEM option power supply enable simple integration into sophisticated scientific instrumentation.
