Foundry survice

Our Foundry survice primarily support from panel assembly to substrate mounting both Glass-Silicon and Glass-Glass structures.
In particular, for microdisplays, we can also handle module integration.
If you customers provide us with silicon wafers, we support small-lot production from prototypes to mass production. Please feel free to contact us if you have any specific quantity requirements or other requests.
 

Applications
 

  • AR / VR
  • Microdisplays: LCOS panels, HUD, HMD, Projectors, etc.
  • SLM: Reflective, Transmissive, WSS etc.

Liquid crystal optical elements

Our liquid crystal optical elements are products that using Glass-Glass cells.
Utilizing our proprietary ultra-compact and ultra-thin technologies, we support a wide range of custom products.
Leveraging our extensive know-how in liquid crystal technology gained over many years,we provide products tailored as closely as possible to customer desired specifications.
We can propose suitable liquid crystal materials such as FLC or Nematic liquid crystals, according to customer requirements.
Please feel free to contact us if you have any specific requirements.
 

Ultra-compact optical elements

Ultra-thin optical element


Half wave plate (HWP) / Quarter wave plate(QWP)

These wave plates can control phase retardation for a specified wavelength (λ/2 or λ/4) when passing through the cell.
Please inform us of your target center wavelength and wavelength range,and we will do our best to provide a product covering as much of the specified wavelength band as possible.

ColorSwitch

ColorSwitch is a product that integrates ColorSelect™, ColorLink Japan, Ltd.'s wavelength selective retardation film onto the surface of our Glass-Glass LC cells. It provides tunable color filters and wavelength cut filters that transmit or block specific wavelengths from visible light to the near-infrared range.
 

Types
 

  • ColorSwitch (Wavelength Selective Filter)
  • TrimSwitch (Wavelength Cut Filter) 
 

Applications
 

  • Laser reflection prevention for ophthalmic surgery
    (Electrically Controlled Shutter)
  • Microscope (with adjustable light source color)
  • Automotive applications  etc.

Variable Retarder

A variable retarder can actively control polarization and phase, in contrast to a half-wave plate that simply switches between two fixed states. It switches in milliseconds with no moving parts such as motors are required.
Please inform us of your target center wavelength and wavelength range,and we will do our best to provide a product covering as much of the specified wavelength band as possible.
We are currently developing PSV-FLC using FLC to enable intermediate grayscale.

Applications
 

  • Variable modulation devices
  • Phase-difference control of a laser
  • Optical Coherence Tomography (OCT)
  • Liquid Crystal Tunable Filter (LCTF)

Spatial Light Modulator (SLM) panel using ferroelectric liquid crystal (FLC)

This panel is effective for creating arbitrary patterns in space.
By passing light through prisms or other optical components, it is possible to precisely control the phase, amplitude, and polarization of the light.

Applications
 

  • Holography
  • Laser processing
  • Optical communication: signal modulation and optical switching
  • Display technology: high-resolution image display  etc.

Microdisplays Using Ferroelectric Liquid Crystal (FLC)

We offer four types of microdisplays — 0.24, 0.38, 0.40, and 0.50 inch — using FLC.
By incorporating the high-speed response characteristic of FLC, Field Sequential driving is possible*.
Field Sequential driving allows all RGB colors to be displayed with a single pixel,which allows for display with smaller pixels than devices using Nematic liquid crystals or OLED.
Furthermore, the effect of fringe electric field*2 is reduced, resulting in high-resolution images.
 *1 FLC response speed is approximately 100 μs (about 100 to 1000 times faster than conventional Nematic liquid crystals)
 *2 Using Nematic liquid crystal devices have poor pixel shape due to crosstalk, but FLC has not crosstalk
(Figure: Effect of fringe electric field).
 

Applications
 

  • DSC/DVC
  • Smart glasses (HMD)
  • Head-up displays (HUD)
  • Microscopes,binoculars,ophthalmic,measurement devices
  • Sensors (sensing applications)
  • AR/VR glasses etc



Characteristic
 

  • High-speed response
  • Field sequential drive
  • High resolution

Sales of Ferroelectric Liquid Crystals

The key material, ferroelectric liquid crystal (FLC), is developed and manufactured at our Kitamimaki facility in Tōmi City,
Nagano Prefecture, Japan.
 

We provide contract manufacturing and joint development for customer products utilizing FLC, and we also conduct sales of FLC itself.
