Imaging optics - Import export

Befort maintains its own optics design & construction department. Optical designs are developed with the lens design Program ZEMAX© OpticStudio 15. The design process is particularly focused on a proper design for production. The admissible tolerances are a major factor for the price of an optical system, in addition to the selection of suitable glass. You can be assured that we will find the optimal solution for your specific problem based on our experience in the field of optics design. Optical imaging systems, laser optics and illumination systems can be measured and dimensioned with Zemax© OpticStudio 15. The 3D data of the optical design is transferred via an interface to the 3D CAD Product Design Program Inventor and with the support of Inventor the fitting mechanical solution is developed

Customer specific optomechanical and optomechatronic components Our strengths lie in the development and construction of optomechatronic systems from the feasibility study on the prototype tofit system integration. The earlier we are involved in your development process, the more we can do for you. Our experience shows us that especially innovative systems and product ideas benefit from a close partnership. This is what we stand for. In addition, we offer our customers service performance measures and technological support, when it comes to ensuring the quality of their products or production facilities. We measure and test according to your specifications. We make sure that you do everything right from optical design to imaging.

Achromatic systems consist of two single lenses of different refraction that are cemented together. This avoids the inherent achromatic aberrations of single lenses that lead to blurred or distorted images. We produce these highquality optics with diameters of 10 50 mm and focal lengths of 20 250 mm. We supply black anodized aluminium mounts with all achromatic systems on request.

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).
