An optical component for illuminating a sample region with a periodic light pattern comprises: a first waveguide, a further waveguide and an optical splitter. The optical splitter has an input for receiving light, a first output and a second output. The first waveguide is optically coupled to the first output, to direct the first input light into the sample region in a first direction. The second output is optically coupled to the sample region to direct second input light into the sample region in a second direction. The further waveguide is arranged to receive third input light which is directed into the sample region in a third direction. The first direction, second direction and third direction are different from one another. The first and second input light interferes to form a periodic pattern in the sample region. The optical component may be used for structured illumination microscopy.
