Request InfoBristol Instruments Inc.Bristol Instruments offers a family of instruments that use the unique properties of light to precisely measure the critical parameter of thickness. The primary advantage of this optical technique is that it makes non-contact measurements with sub-micron accuracy. Both hard and soft materials are analyzed without damage or deformation. In addition, this optical technique enables the simultaneous measurement of up to 31 layers. Originally designed for R&D and laboratory environments, Bristol Optical Thickness Gauges have evolved into high volume production and in-line quality control...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2021 IssueBring Your Product to LifeDecades of service in the optics industry have given us a proven track record of innovative and practical problem solving that serves the development needs of a diverse portfolio of life sciences...Photonics Spectra November 2021 IssueStepper Motor ControllersThe ADAGIO-X-STPR series of rack mounted standalone stepper motor controllers from Optimal Engineering Systems Inc. are cost-effective solutions for controlling and driving single- and multiaxis...Vision Spectra Autumn 2021 IssueAutofocus Zoom CameraThe Harrier 40x AF-Zoom Camera from Active Silicon Ltd. is a compact and cost-effective autofocus-zoom module with 40× optical zoom in a 101 × 54 × 64-mm footprint.

It is critical that the suppliers and customers have a consistent approach during the inspection process. These guidelines are intended to help ease communication between suppliers and customers for better products and business.Surface quality has become one of the most poorly understood specifications in the optics industry. A significant portion of the confusion stems from the two major competing (and largely...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookCommon Lens Formulas: Formulas for lens focal length, magnification, relative aperture (f/#), object-to-image distance, object-to-lens distance, lens-to-image distance and numerical aperture.WHITEPAPERSPhotonics.com 6/30/2020Health and Sanitization through UV LightingWith increased awareness and necessity for rapid disinfection methods due to the current coronavirus pandemic, ultraviolet disinfection has become a viable method to achieve it.
