671 系列激光波长计采用成熟的基于迈克尔逊干涉仪的技术，可精确测量工作在 375 nm 至 12 μm 范围内的连续激光器的波长。
671A 型是最精确的，测量波长的精度为 ± 0.2 ppm（± 500 nm 处为 0.0001 nm）。对于不太严格的实验，671B 型是一种价格较低的替代方案，精度为 ± 0.75 ppm（± 1500 nm 处为 0.001 nm）。
为了实现最苛刻应用所需的可靠精度，671 激光波长计使用内置 HeNe 激光器进行连续校准。这是理想的参考源，因为它的波长是众所周知的，并且由基本原子结构固定。
为了实现最高精度，671A 型使用单频 HeNe 激光器，该激光器使用平衡纵向模式技术进行稳定。671B 型使用标准 HeNe 激光器作为波长参考。
671 激光波长计与通过 USB 或通过以太网通过局域网直接连接的 PC 配合使用。提供软件来控制测量参数和报告波长数据。
由于波长是使用板载数字信号处理器计算的，因此 671 激光波长计可以使用用于自定义或 LabVIEW 编程的命令库直接集成到实验中。这消除了对专用 PC 的需求，并支持使用任何作系统。
More confident in the results of the experiment
The 671 Series laser wavemeter uses proven Michelson interferometer-based technology to accurately measure the wavelength of continuous lasers operating in the 375 nm to 12 μm range.
Type 671A is the most accurate, measuring wavelengths with an accuracy of ± 0.2 ppm (0.0001 nm at ± 500 nm). For less rigorous experiments, Type 671B is a less expensive alternative with an accuracy of ± 0.75 ppm (0.001 nm at ± 1500 nm).
Accuracy is guaranteed through continuous calibration
To achieve the reliable accuracy required for the most demanding applications, the 671 laser wavemeter is continuously calibrated using the built-in HeNe laser. This is an ideal reference source because its wavelength is well known and fixed by the basic atomic structure.
For maximum accuracy, the Model 671A uses a single-frequency HeNe laser, which is stabilized using balanced longitudinal mode technology. The Model 671B uses a standard HeNe laser as a wavelength reference.
Make it simple
The 671 laser wavemeter works with a PC directly connected via USB or via Ethernet over a LAN. Provides software to control measurement parameters and report wavelength data.
Since the wavelength is calculated using an onboard digital signal processor, the 671 laser wavemeter can be integrated directly into the experiment using a command library for custom or LabVIEW programming. This eliminates the need for a dedicated PC and supports the use of any operating system.
