An optical scanning device for scanning of a first, second and third type of optical record carrier with radiation of a first wavelength \u03bb1, a second wavelength \u03bb2 and a third wavelength \u03bb3, respectively, where the three wavelengths are substantially different. The frame has a burner element that can be a nozzle tube having a commercially available burner nozzle for generating a cooking flame during use. The connector is provided with a clipping device to clip the circuit board and securely connect the connector plug with the connector socket. A terminal portion extending through the mount surface is connected with the circuit board and arranged to deliver the individual information through the circuit board. The first layer has a first refractive index and a first thickness that is a function of the first refractive index.
