The 671 Series Laser Wavelength Meter uses a proven Michelson interferometer-based design to measure the wavelengths of CW lasers to an accuracy as high as ±0.2 parts per million. Operation is available from 375 nm to 12 μm. Continuous calibration with a built-in wavelength standard guarantees the reliable accuracy that is required for the most meaningful experimental results.
Hamamatsu’s H15460-40 PMT module features high sensitivity in the 300- to 740-nm region thanks to the PMT’s GaAsP photocathode, and the PMT’s 14 sq mm effective area offers a wide field of view for two-photon or multiphoton microscopy. The module also contains an HVPS circuit and high-speed amplifier that reduces noise between the detector and electronic devices, improving the overall sensitivity.
