Abstract: An optical unit includes a reflective optical element and an antireflection structure having an average height and an average pitch larger than a maximum wavelength of light contained in an effective light flux. The antireflection structure is disposed outside an optical path of the effective light flux, and the antireflection structure has a plurality of convex portions extending in a predetermined direction. An angle formed between the predetermined direction and the optical path of the effective light flux is from 45 degrees to 60 degrees.

Abstract: Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving location 2 for receiving a sample 3 for analysis; an illumination arrangement 4 for directing light towards a received sample; a detector 6 for detecting light reflected by a received sample; and collection optics 5 for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer 42 and a half beam block 45a, 45b which is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from re-entering the interferometer. A half beam block 45a may be disposed in the optical path between the interferometer and the light source 41 for blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam block 45b may be disposed in the optical path on the opposite side of the interferometer than the light source.

Abstract: An apparatus comprising at least: a first waveguide; a second waveguide; and a diffractive element. The first waveguide guides a first band of onto the diffractive element such that the first band is diffracted at an mth non-zero order over a first range of angles. The second waveguide guides a second band onto the diffractive element such that the second band is diffracted at the mth non-zero over the first range of angles. The second waveguide guides a third band onto the diffractive element such that the third band is diffracted at the nth non-zero order over the first range of angles. Wavelengths of the first band, the second band, and the third band do not overlap with each other. The mth order and the nth order are different from each other.
