Abbe Condenser 2 - Updates and the 'Uber Pol' high NA polariser

This gives updates to the Abbe Condenser design for the 3D printed open source PUMA microscope and introduces the 'Uber pol': A new polariser module that can be used with the full Abbe condenser for high numerical aperture polarisation microscopy. Note: There is an error in the table of focal lengths shown in this video - the fp for the 'original paraboloid' should be 10.5 mm (not 24.0 mm as shown - that is for the 44 mm lens used in the Köhler upper collector). The correct values are given in the GitHub document referenced below. If you haven't seen the original video for the PUMA Abbe condenser you should watch that first:    • The Abbe Condenser with an Intro to Dark F...   CONTENTS ======== 00:00 Intro 00:48 New Receptacle for the 30 mm lens 02:02 Variants of the lenses + Specs 04:04 Checking the Fourier Plane of the Condenser 05:34 The 'Uber pol' Polariser 08:29 Conclusions SUPPORT PUMA ============ PUMA is an open source microscopy project.
