Eulitha’s DTL technology is highly compatible for creating high-precision nanostructures on optical elements like lenses, mirrors, optical fibers, and gratings. This technology enhances the performance and functionality of these components, significantly advancing fields such as telecommunications, imaging, and photonics by ensuring detailed and accurate patterning. DTL uniquely is able to pattern high-resolution structures over curved substrates and substrates with large topography.
Anti-Reflective Surfaces
Eulitha’s DTL technology creates micro- and nanostructures with deep subwavelength periods on surfaces, significantly reducing reflections and enhancing light transmission. These anti-reflective coatings are critical in applications ranging from eyeglasses and camera lenses to solar panels and electronic displays. By minimizing glare and reflections, this technology improves visibility and image clarity, offering extensive benefits for various optical devices and paving the way for advancements in light transmission technologies.
Spectrometer Gratings
Eulitha’s DTL technology is commonly used for producing Spectrometer Gratings, which are used in many analytical and sensing applications. This technology has the ability to create not only extremely precise linear gratings but also curved and chirped (variable line-space) gratings, combining optical functions such as imaging and focusing with wavelength dispersion.
Laser Diffraction Gratings
Eulitha’s DTL technology is key to producing large-area diffraction gratings with extremely high pitch accuracy and wavefront control. These gratings are essential for manipulating light emission in lasers, spectroscopy, and optical communications. The high precision and large-area printing capability of Eulitha’s tools enable production of gratings with extremely high level of wavefront control for applications such as pulse compression gratings.
Wavelength Selective Switches
Wavelength Selective Switches (WSS) are essential devices in modern fiber-optic communication networks, particularly in Dense Wavelength Division Multiplexing (DWDM) systems. They facilitate the routing of individual wavelengths or groups of wavelengths, allowing for flexible network management and optimization. WSS operates by separating the incoming light into different wavelengths, switching them to desired output ports, and then recombining them for transmission. This ability to dynamically manage traffic not only maximizes network capacity but also enables quick reconfiguration in case of network failures. With increasing data traffic, the importance of WSS is growing, fostering the development of more advanced and efficient WSS technologies. Eulitha’s DTL technology is used in manufacturing of high-precision diffraction gratings are required in separation and combination of light transmitted in optical communication fibers.
Wire Grid Polarizers
Wire Grid Polarizers are optical components used for controlling the polarization of light. Comprising a series of parallel metallic wires, usually made of aluminum or silver, they function by selectively transmitting electric fields oscillating perpendicular to the grid lines while reflecting those parallel. This application requires deep subwavelength periodicity, typically around one third of the wavelength of light. Such patterned surfaces can be considered as meta-surfaces along with anti-reflection structures. Eulitha’s PHABLE technology is ideally suited to produce large area wire grid polarizers with the required periodicity and uniformity.
Diffractive Optical Elements
Sports Optics – Reticles
Reticles, an essential component of sports optics, are the crosshairs or aiming point seen in the field of view in devices like riflescopes, binoculars, or telescopes. They provide a precise point of focus or alignment, critical for activities like hunting, shooting, or stargazing. Reticles come in a variety of designs, from simple crosshairs to complex patterns, and may include features like bullet drop compensation marks for accurate long-range shooting. Some are illuminated for better visibility under different light conditions. Diffraction gratings are used in such illuminated reticles to couple light in and out of transparent glass substrates, very much similar to the waveguides used in the AR application. Eulitha’s DTL technology is used in printing the periodic structures on such reticles.
