Since laser interferometer systems are high accuracy, non-contact measurement and easy installation, the systems have been incorporated into such manufacturing equipment as precision cutting machines, measuring machines and lithographic systems. The unit of measure for a laser measurement system is dependent on the wavelength of the laser source. The wavelength in atmosphere is affected by the refractive index of surrounding air, which depends on the temperature, relative humidity and air pressure. Without proper environmental control, degradation in system accuracy and repeatability will occur and limit the quality of final products. We have designed and produced a new environmental chamber for precision machine tools with laser interferometer system. The chamber consists of a precise air conditioner, a negative/positive pressure controller and a closed workspace surrounded with the insulating panels. The air conditioner provides the controlled environment within temperature change of 0.2℃ P-V (peak-to-valley) and humidity change of 4% P-V. The negative/positive controller can maintain an even pressure within an accuracy of 0.4hPa P-V by adjusting inside pressure to either negative or positive relative to outside. To utilize the insulating panels for making the chamber frame allows for low cost and easy construction. The fluctuation in the relative tool displacement to the workpiece and the surface profile formed by raster flycutting are measured to verify the environmental control performance for a long period. A fluctuation of 109nm P-V in the displacement and a form accuracy of 91nm P-V are obtained ; both the results demonstrate the highly compensated accuracy due to the new environmental chamber.

由于激光干涉仪系统具有高精度、非接触式测量和易于安装的特点，该系统已被纳入精密切割机、测量机和光刻系统等制造设备中。激光测量系统的测量单位取决于激光源的波长。大气中的波长受周围空气折射率的影响，而周围空气的折射率取决于温度、相对湿度和气压。如果没有适当的环境控制，系统精度和可重复性将下降，并限制最终产品的质量。我们设计并制造了一种新型的激光干涉仪精密机床环境室。该试验箱由精密空调、负压/正压控制器和封闭工作空间组成，工作空间由隔热板围成。空调器提供温度变化为0.2℃ P-V（峰谷）和湿度变化为4% P-V的受控环境。负/正控制器通过将内部压力调节为相对于外部的负或正，可以在0.4hPa P-V的精度内保持均匀的压力。利用隔热板来制造腔室框架允许低成本和容易的构造。测量了刀具相对工件位移的波动和光栅飞切形成的表面轮廓，以验证长期的环境控制性能。实验结果表明，新的环境室具有很高的补偿精度，位移波动为109 nmP-V，形状精度为91 nmP-V。
