© 2020 SPIE. Specimen induced aberrations can have detrimental effects in all types of high-resolution microscope. In this study, we present a sensorless technique that uses a deformable mirror (DM) to correct aberrations of both the system and sample. Using a laser-free confocal microscope, with patterned disk illumination and detection. The system is based on a commercial confocal module (Clarity, Aurox Ltd., UK) that uses Light Emitting Diode (LED) illumination to obtain optically sectioned 3D images. The results obtained show that the setup was able to correct aberrations of biological samples used in the study. These systems will help researchers working on various biological systems to obtain improved quality images when focussing deep into thick specimens.
