General agent of fully automatic WPA-200 digital stress distribution detector

The WPA-200 series is a birefringence/stress measuring instrument developed by the Japanese company Photonic Lattice. The PA series measures birefringence within a range of 0-3500nm and can measure samples ranging from a few millimeters to nearly 500 millimeters. The PA series birefringence measuring instrument, with its technology of photonic crystal polarizing array and birefringence algorithm design and manufacturing, has the ability to measure each sample in just a few seconds, making it the choice for birefringence measurement/stress measurement in the industry, especially in the industrial sector. It is the general agent of the fully automatic WPA-200 digital stress distribution detector

（1） Product Technical Parameters

（2） Core Technology Highlights

1. Principle innovationBased on the photoelastic effect, a non-contact global measurement is achieved by integrating photonic crystal polarization array and polarization photoelectric vector synthesis technology.

2. efficiency breakthroughOne time global imaging, replacing point by point scanning, supporting real-time monitoring of the production line.

3. Maintain advantagesNo mechanical rotating parts, modular design reduces downtime maintenance costs.

（3） Application scenario expansion

• Optical fieldVR/AR Pancake lens stress detection (controlling Δ n<10nm), optical film substrate stress analysis;

• industrial manufacturingControl of edge distortion of car HUD cover plate (<0.5%), optimization of annealing process for quartz glass tube (reducing cracking rate by 60%);

• semiconductor fieldIdentification of submicron level stress defects on glass substrates, compatible with SEMI F40 standard.

3、 Background of Japanese Photonic Lattice factory

2. Company ProfileOriginating from Northeastern University's photonic crystal technology in 2002, headquartered in Sendai, Japan, focusing on the research and development of optical measurement systems, it was acquired by high-speed imaging Photron in 2020.

3. Technology InheritanceThe core technology of "self cloning photonic crystal preparation method" has been recognized by the industry, and WPA-200 was certified as an "excellent product" in Miyagi Prefecture in 2015.

4. product iterationThe WPA-100 series was launched in 2009 and upgraded to WPA-200 in 2015, becoming the mainstream equipment for stress measurement in the industrial sector.
