Coating

In support of our products for different applications, II-VI has invested a world class coating and metrology facility, which includes Vecco IBS, Leybold and Optorun IAD/EB, Internally-designed MS, and other domestic coating machine. Teamed with the coating engineers in Fuzhou, Guanghzou, Santa Rosa, and Florida, II-VI can provide anti-reflective, high reflective, partial reflective, mirror, beam splitter, and filter coatings for applications including Telecom, Industrial Laser, Life Science and Instrumentation with wavelength range from deep UV to NIR.

Advanced Coating Center

II-VI Advanced Coating Center located in Santa Rosa, CA designs and manufactures high performance optical coatings for telecom, industrial, and life science applications. With the use of our advanced coating chambers, our state-of-art automated production facility, and our world class thin film design engineering team, Photop Advanced Coating Center can provide the coating solution you need. 

• Standard AR, HR, Mirror, PBS coating
• Deep UV coating from 120nm
• High reliability filter coating
• High-end non-polarization beamsplitter (NPBS) coating
• High energy laser optical coating for wavelength range of UV to NIR

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.

IBS Coating

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.

MS 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.

 

 

Diffraction Gratings

II-VI’s diffraction gratings feature precise periodic structures that achieve diffraction with high wavelength resolution. Our products are manufactured using II-VI in-house holography, ion-etching and replication processes. II-VI provides planar and concave reflection gratings and planar transmission gratings for various applications including in wavelength selective switches (WSS) in communications and in ultrafast lasers for materials processing.

Capabilities

  • Optics are available with Aluminum, Gold, Silver, Dielectrics and/or AR Coatings
  • All products are manufactured using volume precision grating fabrication techniques
  • Quality control parameters include: efficiency, stray light and laser damage tests
Filters

Optical filters selectively transmit light in a particular range of wavelengths and block the remainder, passing the long or short wavelengths only(singpass), or blocking both longer and shorter wavelengths (bandpass). With our unique IBS and MS coating technologies, Photop Optics provides reliable filters with high performance, such as OD6 filters, Linear filters, Notch filters and others.

Flow Cells

The II-VI Optics engineering team has developed unique processes that provide high reliability and high performance flow cell products for flow cytometry, hematology analysis and other systems. With our precision optical CNC processing, we offer different types of flow cells with different shapes, cuvette dimensions, and cuvette sizes.

Focusing Lenses

A lens is a curved piece of ground and polished or molded material, usually glass, used for the refraction or focusing of light. Photop provides lenses a wide range of size and materials including BK7, Fused Silica, CaF2 and other glass types specified by customers. Similar to the cylindrical lens, spherical lenses are also widely used in the different applications, and II-VI provides singlets, doublets and customized lenses assemblies.

Lenses Assembly

Based on our strong Design and Package technologies at our NPI production, II-VI also designs and assembles Rod Lenses for Endoscopy, Objective Lenses, Beam Expander, and other customized assemblies.

Objective Lenses

The objective lens is an optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objective Lenses can be as simple as a single lens or more complex combinations of several optical elements. II-VI designs, fabricates and assembles high performance objective lenses for use in many applications.

Optics for Display

Based on our new product introduction (NPI) team, micro-optics and precision optics manufacture platforms, II-VI is providing various optical products for consumer and industrial applications, which include dichroic filters, LED extracting lens, light pipes, CMOS windows, large size optics and precision cube assemblies for projector light engine, LED light source modules, automobile and solar products.

Optics for Surveying

Integrated with our Green Laser products in our laser group, II-VI provides the total solution for Surveying and Construction Instruments like Auto Lever, Rotating Laser, and Total Station. Our key products include Green Lasers as the laser source, lenses to shape and collimate the beam, prisms to deflect the beam or rotate the image, and windows and assemblies.

PACC Filters

II-VI Advanced Coating Center located in Santa Rosa, CA, designs and manufactures high performance optical coatings for life science and telecom applications. With the high energy reactive magnetron sputtering technique known as “Advanced Energetic Deposition (AED)”, PACC is enabling hard coating and superior performance. PACC provides a full range of filters optimized for a variety of life science and telecom applications.
