Applications for Ion Beam Sputtering (IBS) Coatings

High Power Laser Applications

The high density and low loss exhibited by Ion Beam Sputtering coatings, make them perfectly suited for laser optics and applications. ECI can deposit AR coatings with reflection of less than 0.03%. ECI can also deposit dielectric mirror coatings with reflection greater than 99.9%, which exhibition absorption and scatter loss of less than 10ppm. Evaporated Coatings’ IBS coatings for laser applications perform very well when used with high power lasers. ECI has deposited IBS AR coating that can withstand greater than 40J/cm^2 for a 10ns pulse width at 1064nm and 2GW/cm^2 for continuous wave at 1064nm. ECI has deposited dielectric mirror coatings that can withstand greater than 60J/cm^2 for a 10ns pulse width at 1064nm. While these coatings can be deposited on a variety of different substrates, laser damage threshold will depend on the type and quality of your substrate. ECI’s Ion Beam Sputtering coatings are also great for applications that use ultrafast lasers.

Medical Applications

Ion Beam Sputtering coatings are ideal for a variety of medical applications because of increased environmental stability, low loss characteristics, and their ability to meet very strict optical requirements. ECI produces broad band dielectric mirrors using Ion Beam Sputtering for many medical imaging applications. These applications range from scanning mirrors to intra oral mirrors. Some such mirrors are even deposited on the ends of fiber optic assemblies that will be inserted into the human body. ECI can also produce excitation filters, emission filters and dichroic filters for applications that utilize fluorescence microscopy.

LiDAR Applications

Specialized mapping and geographical information systems (GIS) technology are using a specific laser technology known as LiDAR (Light Detection and Ranging). LiDAR is a unique and versatile laser system that actively sends light energy to the ground, allowing for information to be sent back to the sensor regarding surface composition, elevation, etc. LiDAR can also be used for safety features on vehicles, as well as for testing methods for law enforcement officers and traffic safety. Through targeting the transmittance of certain wavelengths, sensors can interpret these readings to analyze speed and proximity to nearby objects. The precision of our IBS coatings make them an ideal match for filters and mirrors used in LiDAR systems.
