An IPHYS BIF user has lately faced the problem of the depth of field (DoF) for its Optical Projection Tomography. A highly geometrically alternating sample of fascia was blurred for certain projections which compromised the 3D reconstruction. After a little of reversed engineering, calculations, sketching and part delivery. We incorporated the aperture behind the objective to increase the DoF by three fold. If you need some customized solution for your project. That’s what we do! If you have some large objects that needs to be imaged as a whole, for optical clearing and image acquisition, please, contact firstname.lastname@example.org.
