    摘要: An optical filter is disclosed including two laterally variable bandpass filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. This happens because an oblique beam transmitted by the upstream filter is displaced laterally when impinging on the downstream filter. The lateral displacement causes a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap.

    摘要: A microplate reader includes a pair of linear variable filters (LVFs) that together form a wavelength selector. Movement of one or both of the LVFs enables selection of the desired center wavelength and/or passband used to analyze a sample on a microplate inserted into the microplate reader. The microplate reader may also include a similar second wavelength selector. The LVFs are located on movable frames, with each frame also advantageously including least one of an aperture, a fixed optical filter, and an optical polarization filter. In some cases, different types of measurements may be taken without changing the geometry of the optical path between the wavelength selectors. The microplate reader may additionally use a LVF to form a continuously adjustable dichroic for sample analysis.

    摘要: Tunable light source systems and methods with wavelength reference capability are disclosed. A method includes reference filtering a portion of a tunable light beam while the tunable center wavelength λC is tuned over a range by adjusting a wavelength tuning parameter x. The method also includes detecting the reference-filtered tunable light beam and generating therefrom at least one detected light spectrum as a function of the tunable center wavelength λC. The method further includes determining a reference wavelength tuning parameter xCR corresponding to a reference tunable center wavelength λCR based on a maximum value of the at least one detected light spectrum.

    摘要: An optical analyzer (14) for performing spectral analysis on an optical beam (18) includes an optical filter (28), a mover (30), an optical launcher (36), and an optical receiver (38). The optical filter (28) includes a filter area (46) that is a narrow band pass type filter having multiple alternative center bandwidths that are distributed along the filter area (46). The mover (30) moves the optical filter (28). The first optical launcher (36) directs the optical beam (18) at the filter area (46) so that the optical beam (18) is near normal incidence to the filter area (46). The optical analyzer (14) can be used to simultaneously monitor multiple optical signals. Additionally, the optical analyzer (14) can include a beam redirector (40) that causes the optical beam (18) to make two passes through the optical filter (28).
