Where u is the object distance from the lens and v is the image distance from the lens. Complete step by step answer: Focal length of the concave lens, \[{{f}_{\text{concave}}}=-20\text{ cm}\] Focal length of the convex lens, \[{{f}_{\text{convex}...
Bertrand lens is not used in our setup because the focal length of the CCD camera (XCD-V60CR, SONY) is adjustable to capture the images on the back focal plane of the objective, that is, the Kossel diagrams. For measuring the spatially tunable lasing emission from the PSDDBP sample, the...
