Precision Optical’s belief in having a wide variety of coating deposition technology is one of the reasons we are a world leading in high precision coatings. In addition to our ion-assist capabilities, Precision Optical also has plasma assisted technology. Unlike ion-assist that uses ion beams, plasma assist combines the reactive ions with the coating materials using Argon plasma and in certain applications can yield better spectral performance and greater adhesion results than with other deposition technologies.
