Small-frame Omnichrome helium cadmium (HeCd) lasers from Melles Griot, the world s most compact and rugged highperformance HeCd systems, are ideal sources for automatic optical inspection, biomedical fluorescence detection, confocal microscopy, wafer inspection, and a wide variety of other applications. These systems exhibit excellent pointing stability and mode quality (singlemode versions) as well as long operational life. Omnichrome helium cadmium lasers incorporate a unique internal mirror design that eliminates the losses introduced by optical windows, coupled with a rugged Invar external support structure. The result is a system that has exceptional output power for its size, and, from a cold start, reaches full power and stability in just 15 minutes. The Invar support structure provides outstanding long-term power and pointing stability, ideal for scanning applications.

5 Diode-Pumped Solid State- Polarized Helium Cadmium Laser Systems Available in: Production Quantities Custom Configurations Helium Neon Diode Laser Assemblies $ Linear polarization with >500:1 extinction ratio $ Output power to 80 mw at 442 nm or 25 mw at 325 nm $ Unsurpassed mode quality with 0 ( versions) $ NoiseLock noise suppression circuitry Polarized Liconix helium cadmium (HeCd) lasers, manufactured by Melles Griot, are ideal laboratory instruments. They incorporate dual Brewster windows to ensure optimum polarization, and the NoiseLock feature, standard with most of these lasers, allows the user to suppress beam noise by an order of magnitude over specifically desired frequency ranges. ls with interchangeable mirrors are available to optimize output for either 442 nm and 325 nm, and to ensure excellent mode quality. NoiseLock NOISE SUPPRESSION CIRCUITS NOISE (10db/div.) noise lock off noise lock on FREQUENCY (KHz) By injecting a specific noise frequency into the laser, the rms and p-p noise can be dramatically reduced. NoiseLock enhances the signal to noise ratio for most detection systems by an order of magnitude.
