beamsplitter bs cubes thorlabs cm1 pbs251 the polarizing bs cubes offer almost 100 transmission of each polarization axis and thus yield significantly higher light throughput of the desired polarization holograms are captured by cam 1 at the end of the p polarization axis and the previously wasted s polarization beam is used to view the widefield microscope image through a second camera cam 2 or binocular mounted on the first polarizing beam splitting cube this arrangement allows for the real time viewing or capture of microscope specimens to focus the microscope or capture comparative widefield images as shown in fig1 in the hologram recording p polarization path the back aperture of the objective is projected directly onto the tube lens by use of a 4f relay o bouchal and z bouchal u201c wide field common path incoherent correlation microscopy with a perfect overlapping of interfering beams u201d j europ opt soc rap pub 8 13011 2013 in this implementation we have taken the additional step of using a magnifying relay with the first relay lens having an f 1 80 mm focal length while the second relay lens had a f 2 50 mm focal length this magnifying step decreased the object pixel size while also shrinking the point hologram size improving the signal to noise ratio of hologram recording recall that the finch image magnification without the relay unit is z h f o j rosen n siegel and g brooker u201c theoretical and experimental demonstration of.
