Length measuring system MELOS 530

angleopticaloptical lens

The measuring combination for lenses and optical systems MELOS 530 is the best solution for the comfortable and fast determination of effective focal length, back focal length, radii as well as wedge angles. Measurement of Positive EFL Measurement of Negative EFL Measurement of BFL Measurement of Convex and Concave Radii Testing of Wedge Angles and Parallelism • Fast switching between the different measuring modes. Due to an improved design, no time-consuming change of the measuring system is required. • Direct reading of the measurement results on a stand-alone display unit. All calculations necessary for the evaluation of the negative and positive focal length measurement are performed by the display unit. The results can be stored in a table and transferred to a computer for documentation purposes at a later time. During the measurement process, the user is supported by the integrated help function. It allows even the inexperienced user to quickly get familiar with the usage of the instrument. • Precise adjustment of the image planes through display of the reticle image on the monitor. • Full control over the measurement process by manual adjustment. Here you will find an overview of the typical applications of the MELOS 530 The measuring collimator projects a reticle image to infinity. The specimen produces image of the reticle in its focal plane. The size of the reticle image is determined solely by the known focal length of collimator objective and the focal length of the specimen, which is to be measured.
