Abstract:
An aperture shaped to provide a narrow beam in the horizontal plane but a wider beam in the vertical plane that will provide improved image quality in spectrometers without sacrificing as much throughput as typically experienced using a reduced diameter round aperture along with a method of mounting the entrance slit and the limiting aperture on a transparent block for optical stability and ease of alignment is disclosed.
