    Abstract: A surface plasmon resonance meter is provided, including a backlight module, a line-slot plate, a parabolic mirror, a linear polarizer, a sensing chip, a prism and a photo detector array. The line-slot plate includes a light outlet. A light beam travels in the backlight module, and leaves the backlight module through the light outlet. The position of the line-slot plate is matched on a predetermined focal point of the parabolic mirror. The light beam is reflected by the parabolic mirror to be a parallel light beam, and travels trough the linear polarizer to the prism. The prism includes a light entering surface, a detection surface and a light exiting surface. The light beam enters the prism through the light entering surface, contacts the sensing chip with total internal reflection, and finally leaves the prism through the light exiting surface to be received by the photo detector array.

    Abstract: A micro optical head is provided, which provides sub-wavelength focusing spot and very long depth of focus. The optical head includes a transparent substrate, an opaque film, and at least one sub-wavelength annular channel. After coherent light transmits the transparent substrate supporting the optical head and passes through the appropriately designed sub-wavelength annular channel, the transmitted light can overcome the diffraction limit, and the transmission energy is improved efficiently.
