About Optical Simulation
In order to meet the various requirements of our customers, we possess several in-house optical simulation technologies.
In addition, we are constantly developing simulation technologies to realize state-of-the-art optical elements.
Here is an example.
Optical Multilayer Simulation
Simulation results of transmittance and reflectance of optical multilayers.
They are the key to the accuracy of our photonic crystal products.
Simulates the behavior of light, which is a wave.
It is essential for the design of photonic crystals.
(Beam propagation method, FDTD method)
Simulates the state of polarization.
This technique is indispensable for calibration of birefringence measurement systems and ellipsometers, and analysis of measurement results.

Half-Mirror Polarizer for Laser Cavity
Reflectivity for each polarization can be tuned separately. As a half-mirror in a laser resonance cavity, the element is used to generate and select the output polarization of the laser. Because of its inorganic nature, the element can withstand very high optical power.
KAMAKIRI Birefringence Measurement Module
The KAMAKIRI birefringence measurement module is an effective product in situations where installation on the production line is difficult in terms of space.
This mapping ellipsometer can measure the entire surface of up to φ8" wafers (up to ⌀300mm with option), enabling high-speed, high-resolution surface measurement of film thickness changes of 1nm or less.
By using the near-infrared band for the measurement wavelength, this system can measure birefringence/phase difference distribution even for materials that are opaque to the naked eye. Suitable for measurement targets that transmit near-infrared wavelengths, like chalcogenide lenses, LiDAR automotive components, etc.
Birefringence & Stress Strain Measurement
We have improved conventional birefringence measurement from point measurement to 2-D surface measurement. High-speed, high-precision birefringence measurement contributes to quality evaluation and functional improvement of optical materials.
Full-length, full-width film quality control
With the industry's first full-surface measurement technology for birefringence distribution in optical films, we contribute to the improvement of film quality that leads to the assurance of image quality across the entire display screen.
Ultra-precision micro laser processing
Microfabrication technology is becoming increasingly important for next-generation EVs and semiconductor devices. We support the development of this field with our unique beam shaping, polarization control, and high speed temperature imaging technologies.
