Otsuka Electronics to launch 3D Optical Wave Field Microscope,"MINUK", for measuring invisible and transparent shapes or structures
Otsuka Electronics Co., Ltd. (hereinafter Otsuka Electronics; Hirakata City, Osaka, representative
director and president: Kuniaki Natsume) will start selling the 3D optical wave field microscope,
MINUK, in Japan and overseas on April 11, 2024.
MINUK is a microscopic observation instrument capable of observing optical wavefields—theamplitude and phase of light as a three-dimensional field.
MINUK Features
1) Capable of observing clearly transparent scratches and foreign substances inside thetransparent body2) Achieves both a wide 700 μm (vertical and horizontal) field of view and high 0.5 μm
xy resolution3) Measures one shot (minimum recording time less than 1 msec) over a wide area of
1400 μm in the z-direction
4) Capable of digital refocusing, allowing stepless changes in focus after measurement.
By using Optical Path Difference (OPD) to measure transparent samples, the shape of the lightwave changes due to differences in the refractive index of the object under observation, andcapturing this change allows for clear observation with high resolution in the order of nm.
The measurement is non-invasive and does not require any pre-treatment of the measurement
object. MINUK is useful for daily research and development by providing clear and easyobservation of transparent objects that were previously difficult to observe.
Otsuka Electronics will continue to contribute to the health and lifestyle of people worldwide
with analytical technology using light.
Manufacturer's suggested retail price: 20-40 million yen
