The correction collar is marked to indicate both 360° around the objective and various cover glass thicknesses. The tip of the objective is beveled at 45° to gain some clearance near the sample space. Characterization and performance Resolution, FOV and light transmission...
1a, plane polarized collimated light beam 1 from a quasi-monochromatic laser source 2 is directed onto a parallel surface glass block 3 such that the input beam polarization is either parallel with or perpendicular to the plane of incidence. Under such circumstances the two beams 4 and 5 ...
A classical approach to optical steering or pointing functions is the utilization of a pair of glass wedge prisms that can be independently rotated. The refraction that occurs as light passes through each prism yields an angular offset.
