详细介绍：

LOS双频激光干涉仪是以波长作为标准对位移和几何量进行度量的仪器，LOS采用了自制的稳频激光作为激光光源，精度可达到n m量级。LOS可以在很远的距离达到很高的测试精度和解析度。

LOS系统应用范围广，除了可用于长度的精密测量外，配上适当的附件还可测量角度、直线度、平面度、振动距离及速度等等。

该公司同时提供基于CCD的几何度量系统，使得测量更加灵活、快速，并保证精度。

主要特点：

3年内激光波长精度不低于 0，02 ppm.
激光10年内满足测试要求
激光无需采用任何稳频措施（如加热）
无需预热，开机即可开始测量（一般激光需要预热，使得激光波长稳定下来）
激光波长精度不受反射激光影响！（一般的激光干涉仪反射可导致严重的测量误差）
提供激光气体更换服务，即10年后，可以更换激光管的气体，达到新激光管的性能（拥有自己的**HeNe激光生产技术）
空气和材料温度传感器等均采用无线连接，安装和使用简单易用。
通讯界面可以选 Ethernet， USB and WiFi，并自带独立显示器
标准质保期 36 个月（3年）

位移，速度、加速度测试

Standard LOS System configuration is designed to measure position， velocity and acceleration. A typical application is the calibration of positional accuracy of CNC machine tools. In this measurement the difference between the desired and actual position of the machine's moving part is evaluated. The method of measurement and evaluation corresponds to international standards (ISO 230-2， VDI/DGQ 2617，3441， NMTBA). The whole measurement process and printing of protocol is controlled by the computer programme and is fully automatic.

Software Compensation of Machine Tool Positional Errors

The measured positional errors can be transferred as correction data on line into the machine tool control system immediately after measurement. Considerable improvement of positional accuracy can thus be achieved in a minimum time. The producer delivers software modules which compensate for various control systems (SIEMENS， HEIDENHEIN， DYNAPATH， SELCA， YASNAC， FANUC， ACRAMATIC).

Further Applications

Positional accuracy of a co-ordinate measurement machine can be calibrated in a similar way (VDI 2617 standard). The LOS system is used also for the calibration of dimensional gauges. Laser systems cannot be replaced when precision measurement of long distances (up to 40 meters) is required.

线性度 Straightness 测量

阅读: 1808

Errors in straightness of movement and in parallelity of axes can be measured by the LS 127ST set. The laser beam is split in the LS 127.1 differential beamsplitter into two parallel beams. After going through the optical wedge LS 127.2 the beams diverge at a small angle. The optical wedge functions as the straightness sensor. Reflector LS 127.3， formed by two inclined extremely precise plane mirrors， returns the beams back into the differential beamsplitter. The axis of the mirror reflector defines the straight line reference. This straightness measurement method is less sensitive to air turbulence disturbances than other methods. This straightness set also shows low sensitivity to possible inclinations of the straightness sensor during its movement at measurement.

The standard configuration for position measurement except the LS 20.1， LS 21.1， LS 70， LS 90.1， LS 90.3 is used for straightness measurement. The optical parts are fixed by the set of holders LS 51.
