    Lenses for Machine Vision

    For over 40 years Sill Optics has been producing telecentric lenses. First in the form of profile projection lenses and since 1989 in the current form for digital cameras.

Product Portfolio

  • Imaging Lenses - for Machine Vision

    • Imaging Optics - Lenses for Machine Vision, biomedical Iamging, Semiconductor inspection and optical metrology

      For several decades Sill optics has been manufacturing and distributing telecentric lenses for industrial image processing. Based on the success of earlier profile projection lenses, a wide range of telecentric lenses for modern image processing applications has been developed according to the constantly increasing requirements. From lenses with coaxial light coupling, to entocentric macro and wide-angle lenses, to telecentric illumination.

      Development as well as manufacturing is done at our own site in Germany. In addition to high quality, our strength lies in our flexibility, which enables us to offer customer-specific solutions, modifications and designs at comparatively short notice.

              • Telecentric lenses

                • Sill Optics has been manufacturing high-end telecentric imaging lenses for many years. These lenses are specifically designed for measurement applications in industrial machine vision, aiming to eliminate magnification changes and measurement deviations caused by depth of field or defocus.

                  With the increasing data rates and sensor sizes, there is a clear trend towards larger sensor diagonals and smaller pixel sizes. As a result, our lens portfolio focuses on lenses optimized for small pixel sizes, supporting sensors up to 1.5" (with a sensor diagonal of 24.0 mm).

                  Benefit from our extensive experience and expertise in telecentric imaging lenses. Contact Sill Optics today to discuss your specific requirements and discover the right lens solution for your measurement applications.

                    • Telecentric imaging lenses

                    • Parallel light rays: Telecentric lenses are designed so that the light rays are parallel to the optical axis of the lens and strike the image sensor or detector plane perpendicularly. This means that the rays arrive essentially parallel to the optical axis and have no diverging or converging rays.

                      Advantages:
                      This telecentric light path has several advantages, including the elimination of parallax errors, uniform image quality over the entire working area, and the ability to accurately measure objects and distances.

                      Applications:
                      Telecentric lenses are commonly used in applications where accurate measurement and inspection are required, such as manufacturing, quality control and dimensional inspection.

                    • Entocentric imaging lenses

                    • Diverging/converging light beams: Entocentric lenses allow light rays to converge or diverge toward or away from a focal point inside the lens. This means that the light rays are not parallel to the optical axis and diverge or converge as they pass through the lens.

                      Advantages:
                      Entocentric lenses are more flexible in terms of depth of field and working distances because they do not meet strict telecentric requirements. This can be advantageous in applications where variable working distances or depth of field are required.

                      Applications:
                      Enocentric lenses are often used in applications where telecentric requirements are not as strict or where variable working distances are required. Examples include macro photography, microscopy, and some areas of medical imaging.

                          Here you can find the telecentric background illuminations suitable for our telecentric lenses. Various diameters and wavelengths are available. Especially high-precision measurements demand telecentric illumination. This avoids reflections at the edges of objects and increases the accuracy of measurement.
