Fundamental Technologies

Optics

State-of-the-art light control, optical design, sensing and imaging technologies

  • We manipulate light transmission, reflection, refraction and scattering by precisely designing molecules and structures. The technology can be integrated into a compact, palm-sized device.

  • We extract information by measuring the properties of light with high precision. Gathered information is visualized to create value.

Light has the functions of visualizing, recording, detecting, measuring, identifying, photographing, projecting and controlling how things are seen. We apply these functions to imaging technologies such as photography and printing, sensing technologies such as endoscope systems and social infrastructure inspections, optomechatronics technologies such as lenses for digital cameras and TV cameras, and light control technologies such as liquid crystal displays and semiconductor materials.

Manipulating light

Precise control of the transmission, reflection and refraction of light

Through innovative material and structural designs, we improve display performance in TVs and smartphones, and enhance the image quality of image sensors. For example, our light wavelength-selective films transmit only specific wavelengths of light, by controlling molecular alignment at the nanolevel. Precise control of film thickness results in film that uniformly reflects light, even across large areas, without inconsistencies.

Some optical wavelength selective films transmit only red light when white light is applied to them. Additionally, by controlling the thickness of the film and the arrangement of the molecules used, it is possible to create a film that transmits only green light.

Optomechatronics

Delivering the ideal filming experience

Fujifilm lenses feature sophisticated optical systems that combine dozens of individual lenses and precise mechanical structures. These systems are realized and made available to consumers through advanced manufacturing technologies.

Inside a broadcast zoom lens, multiple lens groups work together and move precisely back and forth according to the zoom magnification, creating ideal images without distortion or color shift.

Sensing

Capturing information with light

We have developed technology to elucidate the transmission and reflection states of light within human skin. By analyzing the state of light within the skin at various wavelengths, such as red, green, blue and ultraviolet, we have uncovered the mechanisms behind how skin appears and how ultraviolet light penetrates deep into the skin. This knowledge assists in the development of functional cosmetics.

Imaging

Visualizing hidden information and functions

We use bioimaging techniques to quantify the functions of cells. By developing sophisticated imaging and image analysis technologies, we can visualize the state and activity of induced pluripotent stem cells (iPS cells) for drug discovery and therapeutic applications. This advancement allows for accuracy and the robust quantification of cellular functionalities.
