Reflections from every surface and layer interface are collected and then analysed by an optical interferometer.<\/p>\n<p>This very precise &#8220;optical ruler&#8221; measures the difference in length travelled by each reflection to determine total thickness and the thickness of each layer.<\/p>\n<p><strong>Accuracy, repeatability, and reliability guaranteed<\/strong><br \/>\nThe 137 Optical Thickness Gauge uses proven optical interferometer-based technology used in Bristol\u2019s other products that can be found in research laboratories and manufacturing facilities around the world.<\/p>\n<p>Thickness of transparent and semi-transparent materials can be measured to an accuracy of \u00b1 1.0 \u03bcm, with a long-term repeatability of \u00b1 0.05 \u03bcm.<\/p>\n<p>Performance is guaranteed over long periods of time by continuously referencing the measurements to a built-in intrinsic standard of length. For even greater confidence, every 137 Optical Thickness Gauge is rigorously tested and certified with standards that are traceable to NIST.<\/p>\n<p><strong>Designed for convenience, built to last<\/strong><br \/>\nThe 137 Lower Cost Optical Thickness Gauge is ideal for production and quality assurance applications. Operation is straightforward, making it easy to get reliable thickness measurements every time.<\/p>\n<p>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.<\/p>\n<p>Automatic reporting can be done using LabVIEW, .NET, or custom programming thereby eliminating the need for a dedicated PC.<\/p>\n<p>The rugged design of the 137 Optical Thickness Gauge provides long-term reliable operation, backed by a three-year warranty on all parts and labor. This results in less downtime and low cost of ownership.<\/p>\n<p><strong>Model 137 &#8211; Contact Lens Thickness Reproducibility<\/strong><br \/>\n<iframe src=\"https:\/\/www.youtube.com\/embed\/WlcXAWTT9Jk\" width=\"410\" height=\"231\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Model 137 &#8211; Rigid Contact Lens<\/strong><br \/>\n<iframe src=\"https:\/\/www.youtube.com\/embed\/ZStz3t82pBA\" width=\"410\" height=\"231\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The 137 Series Optical Thickness Gauge uses the unique properties of light to accurately measure thickness of a variety of materials to an <strong>accuracy of \u00b1 1.0 \u03bcm<\/strong>.<\/p>\n<p>To make a measurement, light is directed onto the material under test.
