Abstract: A spectrometer is configured by using a photodetector 1B which comprises a semiconductor substrate 10 having an upper surface 10a, a photodiode array 11 having a plurality of photodiodes 12 aligned on the upper surface 10a of the substrate 10, and a light input section 13 including an opening formed in a predetermined positional relationship to the photodiode array 11; and a main body 2 having a plate portion 20 and support portions 21 and 22 mounted on the substrate 10 of the photodetector 1B. The spectrometer is provided with a lens 23 protruded from a lower face 20b of the plate portion 20 and a planar aberration-reduced blazed reflection diffraction grating 24 provided on an upper face 20a of the plate portion 20 for separating incident light having entered through the light input section 13 and passed through the lens 23 into its spectral components, and configured to detect the spectral components with the photodiode array 11. Thus, a photodetector capable of improving the positioning acuracy of components when it is applied to a spectrometer and the spectrometer using the same are realized.

Abstract: Concentric spectrometers are plagued with internal reflections due to the inherent nature of more than one optical surface possessing a common center of curvature. Reflections from optical surfaces arise when there is a difference or change in the refractive index of the media in which an optical beam or ray of a given wavelength is propagating. Internal reflections in concentric optical systems can produce a myriad of undesirable optical phenomenon at the image plane such as multiple images of an object, interference fringes, and stray light. As a result a loss in contrast or detection limit arise from such phenomenon in which light or detectable radiation that impinges on the image plane does not add to the formation of the intended image, (stray light). The present invention produces high quality images without the optical phenomenon(s) that arise from internal reflections by removing the reflected radiation from propagating through the optical system.

Abstract: The invention features an optical medium for calibrating UV absorbance detectors, methods for making such an optical medium, and methods for calibrating UV absorbance detectors using such a medium. The optical calibration medium includes a gel-sol silicia glass monolith with a rare-earth dopant therein. The rare-earth dopant exhibits at least one spectral feature in at least the far UV range. The constituents of the gel-sol silicia glass monolith are selected so the rare-earth doped sol-gel glass monolith exhibits a transmittance in the far UV range so each distinct spectral feature of the rare-earth dopant in the far UV range is discernable.

Abstract: A modified concentric spectrograph for diffracting light with high stray light rejection without astigmatism is provided. The modified spectrograph includes a grating, a lens, and at least one entrance port and one exit port. The grating has a concave surface and a meridian plane with a first side and a second side. The lens has a substantially planar surface and a convex surface. Preferably, the convex and concave surfaces are substantially concentric. The ports are substantially located on different sides of the meridian plane near a focal plane of the spectrograph. The position of a focal plane may be modified using an optically transmissive triangular prism with a reflective surface, and an optically transmissive block. The position of a focal plane may further be modified with one or more optically transmissive plates. Methods for using the spectrograph are also provided.

Abstract: An optical transmission spectrometer for transmission measurements of absorbing and scattering samples includes light sources mounted parallel to each other in a holder. The beams of light eminating from the light sources are directed through a beam-combiner. The beam-combiner includes a first refractive surface at an angle of incidence of 45°. The first refractive surface refracts light toward a common axis. The beam-combiner includes a second refractive surface parallel to the first refractive surface for refracting the beam of light along a common axis parallel to the original direction of the beam of light. The beam-combiner can include additional refractive surfaces for other beams of light to combine the beams of light into a primary beam. The includes a collimating tube extending along the common axis for baffling stray light and directing the primary beam through a sample. A second collimating tube is provided on the side of the sample opposite the first collimating tube for baffling stray light passing through the sample. The second collimating tube directs the primary beam to a detector package mounted in a holder, where the detector viewing area of the sample is limited to that of the primary beam.
