一種新的簡單且緊湊的可調(diào)諧濾光方法，將單色儀的靈活性與薄膜濾光片的成像功能結(jié)合在一起，非常適合用于照明和圖像采集。

傳統(tǒng)的濾光工具（例如單色儀和濾光輪）都有一些限制，常常使得它們在科學(xué)和工業(yè)領(lǐng)域的使用受限。但是，現(xiàn)在有一種稱為可調(diào)波長選擇器（FWS）的新型濾光裝置，在照明和圖像濾波領(lǐng)域提供了許多優(yōu)勢。具體來說，F(xiàn)WS裝置將單色儀的波長可調(diào)諧和帶寬控制特性，與濾光輪的圓形均勻孔徑結(jié)合在一起。這類裝置高效、簡單且節(jié)省成本。在本文中，我們將介紹這種創(chuàng)新產(chǎn)品，并展示其在寬帶燈中的應(yīng)用。

A new simple and compact approach to tunable wavelength filtering combines the flexibility of a monochromator with the imaging functionality of a thin-film filters, and is ideal for use in both illumination and image acquisition.

Traditional tools for wavelength filtering, such as monochromators and filter wheels, all have some type of limitation that often compromises their use in scientific and industrial settings. However, a new type of wavelength filtering device called Flexible Wavelength Selector (FWS) now offers a combination of advantages for both illumination and image filtering. Specifically, FWS devices combine the wavelength tunability and bandwidth control of a monochromator with the circular uniform aperture of a filter wheel. These devices are highly efficient, simple, and cost-effective. In this article, we describe this innovative product and show its application with broadband lamp.
