Power Technology Inc.Request Info
 
4-mW Blue Laser Power Technology Inc.'s 4-mW blue IQ laser diode module is a lower-noise alternative to 473-nm Nd:YAG lasers. The instrument-quality device operates at 473 ±5 nm and has a precision current source and a PID temperature control loop. It is suitable for fluorescence, spectroscopy, high-resolution printing, interferometry, microscopy and other applications that require a stable wavelength and output. Features include an adjustable focus and quality glass optics. Available with standard elliptical output or with a circularized beam and with continuous-wave or modulated output, the laser diode can operate in constant current or automatic power control mode. Beam-expanding optics are optional.

GLOSSARY
fluorescence
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
interferometry
The study and utilization of interference phenomena, based on the wave properties of light.
