Fluorescent Seeding Particles for PIV Applications
|
|
|
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. >> Technical Handbook |
