Multiband Filter Set Terminology

Fluorescence imaging has revolutionized the study of biological samples, offering insights into cellular dynamics and molecular interactions. Traditionally, capturing high-quality multi-color images involved cumbersome processes, such as switching single-band filter cubes and subsequent electronic synthesis. While effective, this method suffered from pixel shift and sluggish image acquisition.

Semrock's BrightLine ZERO filter sets addressed the pixel shift challenge, yet the demand for swift, high-fidelity imaging persisted. Recent strides in multiband optical filter technology present promising alternatives. Three configurations—full multiband, Pinkel, and Sedat—emerge as frontrunners, each offering distinct advantages in speed, contrast, and image fidelity.

Discover how these advancements are reshaping simultaneous multi-color imaging, meeting the demands of real-time analysis in live-cell studies and beyond.
