This invention relates to a chip holder kit for a wire-grid sensor, where the chip holder kit includes a base plate, where a first aperture is formed at the front side of the base plate, a second aperture is formed at the rear side of the base plate, and an overlapping region where the first and the second apertures overlap. The second aperture has an area that substantially matches the area of the wire-grid sensor and is adapted to removable receive the wire-grid sensor. The first aperture is adapted to removably receive the polarization structure and the first and second apertures are arranged such that when the wire-grid sensor and the polarizer are received in the overlapping region the polarizer filters any incoming excitation light to a transverse electric mode (TE) polarized excitation light before the wire-grid sensor is illuminated.
