On July 2, 2020, staff from Changguang Chenspu brought several core products to Shanghai, kicking off their visit to the Munich Shanghai Optics Fair.
On July 3, the exhibition kicked off as scheduled. The area in front of Changguang Chenspu’s booth was bustling with visitors coming and going. As a technology that has only recently come into the public spotlight over the past two years, attendees posed a wide range of questions about hyperspectral imaging. Teacher Wang Xiaoyi and our staff members patiently answered each question one by one. In the afternoon, Ms. Yang Fei, our company’s Deputy General Manager, delivered a keynote speech on hyperspectral imaging. Starting from the concept of pinhole imaging, she shared a story about how humanity has continuously advanced image technologies, driven by the aspiration to capture the world around us from ever more dimensions. She explained, in a clear and accessible manner, how hyperspectral imaging works by enhancing the spectral dimension to reveal detailed information about materials—and through this, helped even more people gain an appreciation for the technology. Hyperspectral imaging, together with rapid imaging and high-resolution imaging, is bound to become a powerful tool for humanity’s understanding of the world.

In this exhibition, our company’s exhibits can be mainly categorized into three types: Filter products, hyperspectral camera products, and miniature spectrometer products.

Filters have always been a core product of our company. Leveraging our robust design and manufacturing capabilities, we have developed a comprehensive filter product line that includes specialized filters such as deep-ultraviolet filters for day-blind applications, linear gradient filters, and pixel-level filters. Among these, our linear gradient filters boast industry-leading performance nationwide, while our pixel-level filters are uniquely available in China. Our guiding principle is: We can make filters that others can’t, and when others can make them, we can do even better. The hyperspectral camera is an extension of our company’s filter-based products. Our push-broom and staring-type hyperspectral cameras, which utilize linear gradient filters, can perform hyperspectral imaging of targets within the spectral range from 400 nm to 1000 nm. The number of spectral channels can be adjusted between 50 and 200, depending on application requirements. Our snapshot hyperspectral camera, which employs pixel-level filters, enables real-time imaging of targets with a frame rate of up to 90 fps and a spectral range from 600 nm to 800 nm. The key advantages of our hyperspectral cameras include their compact size, light weight, and low cost. Currently, these cameras have been widely adopted in precision agriculture and water quality monitoring. In addition, at this exhibition, we have reached preliminary cooperation agreements with several organizations focusing on defect detection.

The miniature spectrometer is our company’s latest product, which, compared to traditional spectrometers, features ease of portability and convenient operation. By downloading our company’s app, the spectrometer can connect to your smartphone via Bluetooth, enabling it to scan the reflectance or transmittance spectrum of a target object. The scanning results can be viewed directly on your smartphone.

This year’s Optics Expo has provided our company with a platform to promote ourselves to the general public, enabling more people to recognize the advantages of spectral imaging and its promising prospects in the field of identification and detection. The face-to-face interactions with suppliers and customers have also given us a deeper understanding of our own shortcomings and the pain points in the market. We’ve benefited greatly from the Shanghai International Optoelectronic Exposition in Munich, and we’re looking forward to gathering here again next year!
