Density: 0.985g/cc - 1.005g/cc (Designed for Water Suspension)Daylight Color: Fluorescent Red (607nm Peak) Fluorescent Response: Fluorescent Red under 300-550nm wavelengths. Works well with Green Lasers. Peak emission of 607nm when excited at 575nm Particles in Size Range: >90% Spherical Particles: >90% Polyethylene microspheres are hydrophobic and suspend easily in oil-based solutions. They can also be suspended in aqueous solution if coated with a surfactant prior to suspending in...
