Measurement of microscope objective lenses
Lens assemblies and optical systems used in microscopy, endoscopy and other imaging processes in the medical technology sector often have to meet the highest demands. In addition to achieving the highest imaging quality, it is also vital that the field curvature is minimised and chromatic errors corrected..
The measurement of the transmitted wavefront error enables precise determination of image quality and active alignment of optical system aberrations.The ability to perform a detailed Zernike analysis of the wavefront, on-axis and in the field, as well as measuring at different wavelengths, provides a clear advantage over traditional MTF methods. Used worldwide in production, quality assurance and R&D, Optocraft’s wavefront measurement technology contributes to the improvement of optical processes and systems in medical applications.
Characterization of medical lasers
The SHSLab wavefront sensor is a specialist tool that is used to characterise and align laser-optical systems for diagnostics or therapy. Femtosecond lasers, such as those used in LASIK, are complex optical systems that require expert knowledge and experience to align. The wavefront measurement simplifies the alignment process at various points and also provides a quantitative evaluation of the collimation and the laser beam quality after the adjustment has been completed.
Wavefront solutions for medical technology
Systems and modules of the SHSInspect family measure the transmitted wavefront, PSF and MTF. Moreover, they provide information on colour aberrations, focal length and polarization effects, and enable measurements at field points. SHSLab wavefront sensors deliver fast and precise measurements at a wide range of wavelengths.
