The 521 Series Laser Wavelength Meter is intended for scientists and engineers who need to know the absolute wavelength of their laser, but do not need to know it to the highest accuracy provided by the 621 series. The model 521 is a compact system that provides accurate laser wavelength measurement, and is offered at a very attractive price.
As with the high-accuracy model 621, the 521 Laser Wavelength Meter uses Michelson interferometer-based technology to measure the absolute wavelength of virtually any CW laser to an accuracy of ± 10 parts per million. The model 521 differs from the 621 system by using a Moiré scale as a built-in reference. This high-resolution scale provides the continuous calibration that is necessary to guarantee the accuracy of the wavelength measurement.
Two versions of the model 521 are available to satisfy the needs of most experiments. The 521-VIS operates over the wavelength range of 350 to 1100 nm, and the 521-NIR has an operational wavelength range of 500 nm to 1.7 um. A convenient pre-aligned fiber-optic input accepts that laser under test. Instantaneous wavelength information is provided with a measurement rate of 10 Hz. And, a USB instrument interface results in automatic laser wavelength reporting and control. |
