APPLICATION OF FLUIDIC CONTROL WITHIN A PLANO-CONVEX SINGLET LENS

ABSTRACT

This paper focuses on designing a computer code for the purpose of developing a systematic method for continuous control of the focal length of a plano-convex fluidic lens and utilizing the code for studying the optical behavior of a plano-convex fluidic lens. A syringe, which was controlled by a syringe pump controller, was utilized for fluid control. The code decreased the operation time for the syringe pump controller by replacing the manual push of buttons with a few clicks on a computer. By utilizing the code, the focal length of the fluidic lens was measured as a function of the curvature of the lens’ flexible membrane. This was accomplished for three lasers of differing wavelengths (red: 633 nm; green: 543 nm; blue: 488 nm). A graphical relationship was found for the three wavelengths: as the lens curvature increased, the focal length decreased. In addition, as expected, the longer wavelength outputted a longer focal length per lens curvature.
