  Introduction In precision engineering, the precise measurement of gear teeth is essential to guarantee the performance and longevity of mechanical equipment. Gears in automotive, aerospace, or industrial applications play a vital role as components that need to adhere to strict dimensions. Even minute discrepancies in gear teeth may cause inefficient machine performance or total breakdown. This is where Optomech's Optical Profile Projector steps in—providing a non-contact, high-accuracy measurement solution for checking the geometry of gear teeth with micron-level precision. In this in-depth guide, we will discuss how Optomech's optical profile projector measures gear teeth, why it is used in different industries, and how manufacturers can leverage this technology for quality control and precision manufacturing. What is an Optical Profile Projector? An optical profile projector is a sophisticated measuring device that projects the enlarged image of a component onto a screen f...

  Video profile projectors - optomech  Introduction to Video Profile Projectors Video Profile Projectors, in high accuracy measurement and dimensional metrology, are a tool of great importance that is used during inspection as well as in quality control. Unlike the optical comparator, the video profile projector employs camera-driven, high-resolution complex-software-activated non-contact very precise measurement of correct pieces and parts. Automotive, aerospace, medical device, and precision manufacturing sectors use video profile projectors to check their products to precise specifications. Video profile projectors ' capabilities, advantages, and uses, and why they are the better option for contemporary quality control, are what we will be discussing in this article. What is a Video Profile Projector? A video profile projector, or an optical digital comparator, is a highly accurate measuring instrument which projects a representation of a part onto a screen and takes it wit...

  Introduction to Optical Profile Projectors An optical profile projector , also known as a shadowgraph , is a highly precise measurement instrument used in dimensional metrology . It enables manufacturers to inspect, analyze, and measure the geometry of complex parts with high accuracy. This non-contact optical system is widely utilized in industries such as automotive, aerospace, medical devices, and precision engineering to ensure stringent quality control. How an Optical Profile Projector Works An optical profile projector magnifies the profile of a component and projects it onto a screen for detailed analysis. This is achieved through a combination of: Illumination System – A light source (LED, halogen, or mercury lamp) illuminates the part, casting a shadow or reflected image. Lenses and Optics – High-precision lenses magnify the part’s profile, ensuring accurate representation. Projection Screen – A large, graduated screen displays the magnified profile for measurement a...
