  • Offer Profile
  • Sill Optics is the specialist for quality and innovation in the field of photonics technologies. With regard to customized development as well as standard solutions we have established ourselves internationally and are one of the leading companies in this business. The company with more than 125 years of experience is located in Wendelstein.

    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
  • Lenses for Machine Vision

    • For more than 40 years, Sill Optics has been designing, producing and offering telecentric lenses for machine vision. Based on the success of profile-projection lenses, which are still available, a wider range of telecentric lenses for modern imaging processes has been developed to meet demanding requirements. Furthermore our product range has been extended by lenses with coaxial illumination, entocentric macro optics, wide-angle lenses and telecentric condensers.

      Sill Optics’ philosophy is to develop and produce completely at their own site in Germany. Our flexibility, besides high quality, is also to offer customized solutions, modifications and designs on short notice.

      Custom-made lenses

      Our catalog presents only our most common products. In addition we offer customized systems of special telecentric or entocentric lenses up to complex opto-mechanical systems. Our resources comprise both extensive experience in optical design and mechanical engineering. Production with modern technologies from single prototypes up to medium quantities is possible to meet highest demands.

        • Telecentric lenses

          • TTelecentric lenses are designed with an entrance pupil placed in infinity. Compared to entocentric lenses, only parallel principle rays are imaged through the lens. This ensures a constant magnification for the entire depth of field.

            Specifications of our lenses, e.g. about distortion or resolution, are according our datasheets, which are available at the download section of the product tables.

            Our standard lenses are just an idea of the various adjustment possibilities. Please let us know your requirements.ext
              • Fixed and variable aperture stop

              • Most lenses from Sill Optics are supplied with a variable aperture stop. This provides the advantage to adjust the luminance, resolution and depth of field of the application. Lenses with a fixed aperture stop are indicated with a blue dot. As some lenses are exposed to vibrations or fast motion, we offer the variable aperture stops to be exchanged by a fixed aperture stop. The size of the fixed aperture stop can be defined by a lens with variable aperture, which can be rented beforehand.
              • Coaxial illumination

              • The combination of a telecentric front illumination with the imaging lens is possible for most of our lenses. These coaxial illumination versions are available with a fixed LED of various wavelengths (blue, green, red) or with Ø8mm fiber /spot port or Ø6mm fiber port. The part number changes from S5LPJxxxx to S5LPLxxxx.
              • Variable working distance and magnification

              • Sometimes suitable lenses do not meet the desired working distance for the planned setup. In most cases adjustment to your requirements is possible. Please contact our product and project managers. Modification of the working distance usually results in modified magnification. Thus adaption of the magnification is also possible.
              • Variable sensor mount

              • Most Sill lenses are designed for waveband 450nm – 700nm in the visual spectrum. Thereby monochromatic applications (narrow-banded illumination, black-white sensors) and polychromatic applications (broad-banded or white illumination, color sensors) are possible.

                Please note, that some particular designs are only constructed for one wavelength or a narrow range, respectively.

                Moreover there are special lenses for the UV- and NIR-range available.

                In case of special requirements please contact us for a compatibility check to your specifications.
              • Scheimpflug configuration

              • Due to limited installation space or specific measurement circumstances, an imaging lens might be in a tilted position towards the object. To compensate the resulting blur and deformation in the image, the lens can be mounted to the sensor with a compensating angle. As the compatibility of the lens to the measurement setup depends on various factors (sensor size, viewing angle, magnification, resolution,... ), Sill offers suitable adapters on demand.
              • Glued lenses

              • For lenses which are exposed to severe vibrations or are placed inside moving parts of machines a glued version is recommended.
              • Extended wavelength ranges

              • Most Sill lenses are designed for waveband 450nm – 700nm in the visual spectrum. Thereby monochromatic applications (narrow-banded illumination, black-white sensors) and polychromatic applications (broad-banded or white illumination, color sensors) are possible.

                Please note, that some particular designs are only constructed for one wavelength or a narrow range, respectively.

                Moreover there are special lenses for the UV- and NIR-range available.

                In case of special requirements please contact us for a compatibility check to your specifications.
            • Telecentric illumination

              • 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.
                    • Telecentric illumination

                    • Our condensers, depending on their LED-unit, are divided into three series. Whereas the S6IRIxxxx-line with standard LEDs is designed for low illuminance with constant current, the high-power LEDs offer higher output power and are flashable.

                      In addition the new condenser series S6LTCxxxx offer an integrated dimmer, better illumination homogeneity and even further improved output power.
