Transform your underwater macro photography with the Backscatter Optical Snoot OS-2 for Atom Flash. Engineered specifically for the Backscatter Atom Flash strobe, this optical snoot channels and shapes flash output to isolate small subjects against dramatically dark backgrounds.

Precision Macro Illumination and Easy Handling The Backscatter Optical Snoot OS-2 projects a razor-sharp,circular beam of light directly onto your macro subject. Utilizing the Atom Flash’s built-in white and red LED target lights, the OS-2 casts an exact optical footprint that mirrors the flash beam. This visual targeting capability eliminates guessing games and lets you position light accurately on tiny marine life.

Backscatter equips the OS-2 with a secure bayonet mount, allowing fast, tool-free installation and removal on dive boats or underwater. The package includes two swap-able aperture cards—one circular and one oval—featuring four different hole sizes to adjust beam dimensions for tiny nudibranchs, frogfish, or larger reef subjects. An integrated lanyard loop provides convenient attachment to double-ended snaps for safe storage when swimming between macro sites.
