CCD image in the image plane of two crossed lenses of type 35/1/SU8 for bi-dimensional focusing. The lens apertures are 1.85 mm and the resist thickness is 0.85 mm. The white cross is the focus located 0.16 mm inside the lens. The incident unrefracted beam is light grey in colour and is found at the right and the top of the image. The lens substrates are at the left and at the bottom. The FWHM spot size measures 49 µm vertically and 54 µm horizontally and the maximum gain is G = 29. |
