Nettet5. des. 2024 · Hoffman avoids the costly prisms of DIC, that is the main bonus. The book, Light and Video Microscopy by Randy Wayne has a great chapter on it. It only uses a polarizing filter, retardation film, and slits in filters to to convert phase differences in the specimen into visible differences. Nettet13. nov. 2015 · Slit and Modulator Alignment - Aligning the condenser slit with the objective modulator plate is one of the most critical aspects of microscope …

NettetThe Hoffman design is such that the slits are located at the front focal plane of the condenser as illustrated in Figures 1 and 3. When light passes through the off-axis slit, it is imaged at the back focal plane of the objective (also termed the Fourier plane) where the modulator has been installed. NettetLike differential interference contrast (DIC) technique, contrast is increased by using components in the light path that convert phase gradients in the specimen into differences in light intensity that are rendered in an image that appears three-dimensional (3D).
