“Previously, a lens of this scale would have been impossible to create,” Coelho said. “Window to the Heart serves as an example of what’s possible with the latest advances in design, materials, and fabrication.”

“On the 10th anniversary of the Times Square Valentine Heart competition, what better place to host the world’s largest lens than the Crossroads of the World–one of the most photographed places in the world and a hub for innovative technology and design?” said Times Square Alliance president Tim Tompkins.

Window to the Heart’s Fresnel design is a diffusing lens, rather than a focusing lens like that of a lighthouse or magnifying glass. Instead of projecting light, it captures it.

Form Cell includes a row of Form 2 3D printers, a post-processing solution, and an industrial robotic gantry system, plus software to optimize print scheduling and API endpoints.

This coming Valentine’s Day, the title will transition to a new lens: a 10-by-12-foot Fresnel lens made of interlocking 3D printed bricks. The installation, Window to the Heart, is a collaboration between Formlabs head of design Marcelo Coelho and design studio Aranda\Lasch, and is the winner of the 2018 Times Square Valentine Heart Design Competition. Previous winners include The Office for Creative Research, Collective-LOK, Stereotank, Young Projects, and Situ Studio.

Coelho and Aranda\Lasch chose a Fresnel lens design for the installation. Originally developed for lighthouses, Fresnel lenses are made of a set of concentric annular sections, enabling a large aperture and short focal length without the mass and volume required by a conventional lens design.

Today, the world’s largest lens is located in a lighthouse on Oahu, Hawaii. The Fresnel lens at Makapu’u Point, 12 feet tall, 8 feet wide, and painstakingly crafted out of glass, has held the title since 1893.

Fabricating the lens’ bricks will require running approximately 50 3D printers for two weeks. To minimize labor, lenses will be printed on Form Cell, an automated production system powered by Form 2 stereolithography 3D printers.

Window to the Heart is designed and 3D printed specifically to distort and capture the image of Times Square, optically bending light—and attention—to a heart-shaped window at its center. Visitors can look through the window or photograph themselves within it, completing the loop between the lens of the eye and the lens of the camera.

The lens is composed of 98 concentric rings, and each circle is made of a series of bricks 3D printed with Formlabs’ Clear Resin, which is capable of the resolution and clarity that optical elements require. The entire sculpture is composed of 1,090 bricks.

The installation is segmented into concentric rings that flatten a large spherical curvature while retaining its optical effect. Each individual lens is uniquely designed to act as both a brick and optical element.

The models have the same set of rich features as the cased versions, enabling both automatic and accurate manual control across on-camera pre-processing and over image capture.

The Blackfly S board-level models are perfect for integrating into handheld, mobile and desktop devices due to their 29 x 29 x 12-mm board-level footprint and GigE or USB3 across FPC connection with a latching connector. The models also include a low profile JST GPIO connector and do not need a fixed lens mount.

In contrast to several board-level cameras, the Blackfly S board-level models have a rich set of features applied to the advanced CMOS sensors—the same set of features as the cased model.

A Lens that Reflects Culture “Marcelo and I walked around Times Square and noticed that everyone has their camera out, photographing themselves in the light of the media around them. In this sense, Times Square is a symbol for how we experience our world,” Aranda said. “It is a physical manifestation of our culture, one dispersed and absorbed through cameras and screens.”

3D Printing a 12-Foot Lens Lens making has traditionally involved tedious labor and precision, requiring a series of steps of casting, cutting, and repeatedly polishing glass.

It is uncommon for board-level cameras to combine the latest CMOS sensors and include a complete set of features. The Blackfly S board-level models combine the new Pregius global shutter CMOS image sensors for capturing distortion-free and high dynamic-range images.

The Blackfly Board Level models from FLIR Systems are high performance, machine-vision, area-scan cameras that are specifically designed for integration into limited spaces.

The entire Blackfly S camera range is perfect for embedded systems and offers established compatibility with well-known SBCs and operating systems, such as Linux on ARM, x86, x64 and desktop Windows.

Window to the Heart places the world’s largest lens in one of the world’s most Instagrammed places: the center of Times Square.

Once printed, the individual bricks require cleaning and post-curing, but do not require the laborious polishing process required from traditional lens making.

The Blackfly S board-level models can be readily integrated into well-known SOMs and SBCs with established compatibility. These models allow OEMs to develop lighter, smaller and more economical solutions with rich features and embedded system connectivity.
