Model 590光學監視器 Model 590 Optical Monitor
DUN光學監視器使鍍膜者對光學薄膜沉積進行精確控制，減少了工藝誤差，提高了鍍膜產量。我們的旗艦系統590型，被認為是具有無與倫比的魯棒性 和易用性.

我們還推出了一套完整的現成配件來完成安裝工作.我們的工程人員和內部制造也可根據您的要求提供自定義解決方案，以滿足您的確切需求。

Model 590光學監視器 Model 590 Optical Monitor為今天的精密薄膜涂層提供了所需的最高精度。晶體監視器，通過設計，只測量一個涂層的質量，而不能檢測到由于多個工藝變量之一的變化而引起的層密度的變化。如果不被捕捉到，層密度的變化會導致光學厚度的變化，這會導致性能急劇下降，并可能失去運行和收入。

另一方面，光學監視器通過測量涂層的反射率或透射率，對每一層的光學性能提供連續的實時監測。這種測量與已知的各層光學厚度之間的關系進行了比較，以便能夠實現每一層的精確終止。

圖1.0下面顯示了一個典型的監測芯片反射率與厚度的關系圖，這是由一個涂層設計軟件包生成的。由實心垂直條所指出的圖層終止點表示每一層的端點。當590光學監視器讀出達到這些點時，操作者終止該層的沉積并推進到下一層。

Advantages of Optical Monitoring?

Optical Monitoring provides the highest accuracy needed for today’s precision thin film coatings. Crystal monitors, by design, only measure the mass of a coating layer and cannot detect changes in the layer density caused by a variations in one of the many process variables. If not caught, a change in layer density results in a variation of the optical thickness which can lead to dramatic performance reductions and possible lost runs and revenue.

Optical monitors, on the other hand, provide continuous real-time monitoring of the optical performance of each layer by measuring the reflectance or transmission of the coating throughout the coating run. This measurement is compared against a well known relationship for the optical thickness of each layer so that precise termination of each layer can be achieved.

Figure 1.0 below shows a typical plot of monitor chip reflectance vs. thickness generated by a coating design software package. The layer termination points noted by the solid vertical bars indicate the end points of each layer. When the 590 Optical Monitor readout reaches these points, the operator terminates that layer deposition and advances to the next layer.
