| Product Overview | ||
| The 821 Series Pulsed Laser Wavelength Meter provides accurate wavelength information for researchers who need to know the exact wavelength of their CW laser, pulsed laser, or OPO. A unique Fizeau interferometer-based design measures absolute wavelength to an accuracy of ±600 MHz. A built-in wavelength standard is used for automatic calibration to ensure greater confidence in the experimental results. The model 821 is available in two broad wavelength configurations, 350-1100 nm and 630-1700 nm, to satisfy virtually any experimental requirement. The laser under test enters the system through a free-space aperture, through which a visible tracer beam is emitted to facilitate alignment. Automatic pulse detection triggers data collection for asynchronous operation. The wavelength of every pulse can be measured for lasers operating at repetition rates of up to 200 Hz. The 821 Series Pulsed Laser Wavelength Meter operates with a PC running under Windows 7, Vista, or XP. Wavelength is calculated and then transferred to the PC using a high-speed USB interface. Software for a simple display is provided to report data and control measurement parameters. |
