FLUOSTAR microspheres are polymer 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.
- Moderate size dispersity
- Uniform spherical shape
- Minimal photobleaching
- Minimal dye leaking
- No swelling or shrinking
- Good mechanical stability
