An optical device with a first sub-assembly and a second sub-assembly is described. The first sub-assembly has: an input lens for collimating illuminating light, the input lens having an optical axis, an output lens for focusing collimated light received from a sample, the output lens having an optical axis which is offset and substantially parallel with the optical axis of the input lens, and a first support piece which houses and supports the input lens and the output lens. The second sub-assembly has: an input filter for filtering the collimated illuminating light, an output filter for filtering the collimated light received from the sample, and a second support piece which houses and supports the input filter and the output filter. The first and second support pieces are joined together by a liquid-tight joint. An additional optical device is described wherein a plurality of optical components is supported by a support piece, each optical component being aligned by a groove or channel in the support piece, wherein the groove or channel has a pair of side walls which each engage a respective side of an optical component, and the support piece further comprises an end stop which engages an end of the optical component. A further optical device and a method of manufacturing an optical device are also described. A support piece is grown by a process of additive fabrication in which the support piece is built up as a series of layers, each layer adhering to a previous layer, and each layer being formed in its final shape in accordance with a computer model before addition of the next layer. Two or more optical components are supported with the support piece, each optical component engaging the support piece and being aligned by the support piece relative to the other component(s). |
