Abstract

The technology provides two or more spectrometers with substantially uniform focal lengths. A method includes adjusting a size of a first air gap associated with a first lens in order to modify a first focal length and securing a relative position of a first body and a second body of the first lens to set the first focal length at a first value for a first spectrometer. The method further includes adjusting a size of a second air gap associated with a second lens provided in a second spectrometer in order to modify a second focal length and securing a relative position of a first body and a second body of the second lens to set the second focal length at a second value for a second spectrometer. The first and second values are selected to render the first focal length substantially equal to the second focal length.
