ABSTRACT Emission‐line galaxies are an invaluable tool for understanding the evolution of galaxies in the universe. Imaging deep fields with narrowband filters allows not only the selection of these ...

Astrophotography filters are either narrowband (for nebulae) or wideband (for galaxies and star clusters). Narrowband filters isolate specific light wavelengths; wideband filters let through a broader ...

The Navy is funding the development of a narrowband optical filter that would permit visible and near-infrared lidar (light detection and ranging) systems to operate during the daytime. When deployed ...

An array of electro-optical components fabricated as a silicon-based photonic IC provides narrowband passband and notch filtering above 10 GHz. How an electro-optic PIC can implement RF filtering ...

Santa Rosa, CA- February 27, 2015 Alluxa, the leader in high performance optical filters and optical coatings is pleased to announce our new online store focused on Ultra Narrow Bandpass filters. Our ...

Santa Rosa, CA. -Alluxa, an emerging leader in next generation optical filters is pleased to announce the production of ultra-narrowband filters with very high levels of in band transmission.

Tunable filters are optical filters that are suitable for applications requiring wavelength tuning. Two of their main specifications are the optical density (OD) and the out-of-band rejection. The ...
