Fluostar fluorescent particles

FLUOSTAR microspheres are polymer fluorescent particles encapsulating the fluorescent dye, Rhodamine B, which emits the orange-colored fluorescence when illuminated by a green-colored laser (e.g. Nd:YAG, Nd:YLF).

FLUOSTAR feature the outstanding emission efficiency of fluorescence, which are best suited for PIV applications. The strong orange-colored fluorescence may be even observed by sight using a 5 mW laser pointer.

They feature: moderate size dispersity, uniform spherical shape, no swelling or shrinking, minimal photobleaching, and minimal dye leaking.

They can be used for: single-phase liquid flows, multi-phase flows, industrial large-scale flows, near-wall flows, and stereo PIV.
