title = "Multi-band filters for near-infrared astronomical applications",
abstract = "Filters for astronomical imaging traditionally have a simple bandpass that admits (more or less equally) all the photons within some bandwith Δλ around some central wavelength λ0. However, there are situations where not all photons are equally desirable. We plan to develop and apply multiband filters for practical astronomical application. A multiband filter is a bandpass filter whose transmission dips to zero at select, undesired wavelength ranges. Anticipated applications include (i) OH-suppressing filters, especially in the J band (λc ≈ 1.2μm); (ii) economy of filter slots through multi-band filters used in series with broad blocking filters; and (iii) efficient searches for object classes with highly structured spectra. We present the design and anticipated photometric properties of a prototype reduced-background JR filter, which we plan to buy and test in 2010.",
