IAD EB Coating
lon-assisted deposition (IAD) is the technique that while the film is being deposited, one beam of ions bombard the substrate. EB is the electron beam gun deposition technique. Compare to IBS and MS technologies, IAD/EB coating is less stress, low absorption and less dense, but is suitable for high volume production.
Ion-beam sputtering (IBS) is a method that atoms of materials are bombarded and deposited on the substrate by impact of ions. The second ion source is used to bombard the substrate when the sputtered atoms are deposited on the substrate. IBS makes coating film very dense, very low pinholes, low absorption, increases the adhesion and humidity resistance of films, to make a reliable hard coating.
Start the essential components of Magnetron control sputtering (MS) is a cathode and an anode, between which an electric field is established that produces a specific power density. Similar to IBS, MS can make very good quality hard coatings, it was because the sputtered atoms has the energy of a few eV level even with no second source assisted. Photop Santa Rosa Coating Center is equipped with advanced MS coating machines.

New Product Introduction (NPI)
For our Vertically Integrated Solution strategy and better support to our customers, Photop Optics NPI team work closely together with our customers from design to prototype and volume production. Our NPI production line is equipped with most advanced processing equipment include MRF precision processing machine, large size Planetary Polishing stations, Photolithography processing and advanced metrology equipment, like large aperture ZYGO interferometers, AFM, and engineered performance setups.
Based on our strong Design and Package technologies by our NPI team, and utilizing our unique technology platforms of Optical Contact, Diffusion Bonding, and Seam Sealing, Photop specializes in high reliable opto-opto and opto-mechanical assemblies which enable a wide variety of integration for different instrumentation applications.
Magnetorheological Finishing (MRF®) provides the control of finishing processes and bottom line. This patented, deterministic process combines magneto-rheological fluid a unique, magnetically-sensitive (or “magnetorheological”) material – with sophisticated computer algorithms. It has the unique ability to improve figure and finish simultaneously. Flexible and fast, stable and accurate – MRF does it all. You’ll get predictable and precise results every time.
Photop MRF machine enhances our conventional polishing capabilities to achieve higher level products quality and repeatability with maximal product dimension of 500mm. The surface finish could achieve better than Lambda/50 and surface roughness better than 0.2 nm.
