Abstract
The technology provides two or more spectrometers having uniform focal lengths that facilitate comparing spectral results obtained therefrom. The spectrometers include a collimating lens that receives light rays therethrough, a grating that is optically coupled to the collimating lens, and a focus lens that is optically coupled to the grating. The focus lens includes an outer body having a first lens set, an inner body having a second lens set, and an air gap defined between the first lens set and the second lens set. The inner body is moveable relative to the outer body to adjust a size of the air gap in order to modify a focal length of the focus lens. The inner body moves relative to the outer body to change an image size in the x-dimension. A fastener is provided to fixedly secure the inner body and the outer body.
