Bristol 157/137 Instruments can measure the thickness of transparent and semi-transparent materials to an accuracy of ± 0.1 μm, with a long-term repeatability of ± 0.02 μm. 157/137 Optical Thickness Gauges provide a broad measurement range of 35 μm to 40 mm. Operation of the 157/137 Optical Thickness Gauge is straightforward, making it easy to get reliable thickness measurements every time. Measurement data is calculated using an on-board digital signal processor, transferred to a PC or local area network via USB or Ethernet, and then displayed using a convenient graphical user interface. Automatic reporting can be done using LabVIEW, .NET, or custom programming thereby eliminating the need for a dedicated PC.
