Custom DLC Chamber to Solve Coating Issues with IR Optics
Channel: Dynasil Corporation
Date: 2019-03-08

It's a well-known fact in photonics that a Diamond-like Carbon (DLC) coating is the preferred choice for coating external optics that must withstand the harshest environmental conditions. 

Drawing from decades of experience it was clear to that most customers who needed a #DLCcoating expressed 4 common issues with their supplier.

1. Pinholes
2. Uniformity
3. Stress
4. Adhesion

At EMF, we challenged ourselves to design and develop a system that would address these issues.

• We designed the chamber against conventional industry thinking - our DLC chamber uses a process that coats up
• Unlike typical box coating systems, we chose a circular geometry for our coating chamber to ensure a more uniform coating
• A proprietary PE-CVD deposition technique was developed

These unique attributes enable EMF to achieve:
• Virtually zero pinholes
• Exceptional uniformity
• Low coating stress
• Excellent adhesion

EMF's DLC coating chamber can coat nearly all substrates including Germanium, Silicon, Zinc Selenide, Zinc Sulfide and #Chalcogenides.

EMF can help you save loads of time and money by offering in-house metrology, MIL standards, wiper testing and more. EMF's commitment to quality, continuous improvement and unparalleled customer service make us a trusted partner to handle your most complex #opticalCoatings.
