WebAn increased demand for high-performance optical filters with edge transitions steeper than 0.5% of edge wavelength from 90% transmission to OD6 (-60dB), wide-range blocking beyond OD6, and ultra-narrow filters with sub-nanometer bandwidths has driven recent advancements in thin-film design and coating technologies. WebOct 28, 2011 · The UV-to-optical color does show a weak trend with luminosity, becoming redder at higher luminosities. This is most likely due to dust. At z ≳ 5, we find blue [3.6]–[4.5] colors ∼ −0.3 mag that are most likely due to rest-frame optical emission lines contributing to the flux in the IRAC filter bandpasses.

WebFor optical interference filters, changes in the thickness and refractive index across the part result in changes in the spectral performance or in the uniformity. Among other things, the ability to control the uniformity determines the size of a filter that can be manufactured to a given tolerance. The WebTunable bandpass filters can be used in various fields; some examples: One can realize a broadband tunable light source by combining some kind of white light source (for example, a supercontinuum source) with a monochromator.Compared with a tunable laser, one can cover a significantly wider wavelength region.However, there is a trade-off concerning the …
