Femtosecond Laser Nanogratings Create “Five Dimensional” Storage

March 25, 2016

Scientists from the University of Southampton in the UK have created a new data format that encodes information in tiny nanostructures that are etched into glass discs. A standard-sized disc can store approximately 360 terabytes of data, with an estimated lifespan of up to 13.8 billion years. This breakthrough is not only monumental for records keeping, but also for the optical industry as a whole. The “5D” storage technique has numerous benefits over film, CD’s and other storage medium which have multiple drawbacks. The infographic below shows backup storage media’s expected lifecycle. As you can see the “5D” storage method could be…

Thin-Film Deposition on Flexible Substrates

January 28, 2016

As the touch market explodes in popularity so too does the need for high performance thin-film coatings on flexible materials. These materials include but are not limited to Polycarbonate, Triacetate (TAC), Mylar, and Polyester. For the touch market many of these films are polarized and typically will be bonded to the front surface of the display. The application of these films to displays helps promote optical performance and display acuity. With the addition of broadband anti-reflective films to these substrates numerous advantages can be gained. Among the most beneficial results of adding an anti-reflective coating to a flexible display is the…

Coating Micro Optics

June 18, 2013

As consumer electronics continue to shrink in size and increase in functionality so too will the optics used to power and enable the displays and optoelectronics utilized in these devices. With that being said the need for custom precision thin-film coated micro optics has never been greater. The addition of a thin-film coating to a micro optic could make the difference between an onboard camera application being success or failure due to the coating’s ability to increase light transmission and decrease reflectance both indoors and out. Micro optics are typically created from injection molded polymers. Currently Zeonex E48R is widely…

What is a “Broadband” antireflective coating? What is a “Narrowband” antireflective coating?

June 18, 2013

Many times our industrial optics customers approach us and ask for either broad or narrowband antireflective coatings based on their own unique application. Fundamentally broadband and narrowband antireflective coatings serve different purposes. However there are instances where they can be substituted for each other based on the flexibility of the application and the criticality of the light transmission. Broadband antireflective coatings drastically enhance the efficient light transmission of any optical substrate by reducing surface reflections over a wide wavelength rang. Broadband antireflective coatings also help to enhance image contrast in display applications. A broad wavelength range would be defined as…
