Phosphorescent Microspheres – Long Afterglow Particles

Phosphorescent microspheres in particle sizes 10 to 600 microns are now available from Cospheric LLC. These phosphorescent particles are 90% spherical and appear to be off-white under ordinary daylight or regular room illumination.? However, when the lights are turned off these phosphorescent particles exhibit phosphorescent yellow-green after-glow. The spheres have tight particle size distributions and … Read more

Fluorescent Tracer Microspheres – Properties and Applications

Fluorescent Tracer Particles

Fluorescent microspheres are round spherical particles that emit bright colors when illuminated by UV light. Ability to emit intense color under UV (black light) illumination provides contrast and visibility of microspheres relative to background materials.
