From September 16th to 18th, 2021, Nanjing Kanshijie Intelligent Technology Co., Ltd. (hereinafter referred to as Nanjing Kanshijie) participated in the 23rd Shenzhen Photoelectric Exhibition, where its Snapshot Hyperspectral Camera Protocam-1/-2, based on the newly developed 100-channel filter array chip, made its debut at this highly influential comprehensive exhibition in the photoelectric industry.

Based on the filter array process, the snapshot hyperspectral camera has the ability to extend to different bands such as visible light (VIS) and near-infrared (NIR), with two specifications of multispectral (35 channels) and hyperspectral (up to 140 channels). At the same time, the snapshot hyperspectral camera has a natural advantage in the field of spectrometer, with a collection speed of up to 31.6 cubes/s. The self-developed array filter chip has the advantages of high precision, low cost, and mass production, and can be widely used in smartphones, industrial inspection, agricultural inspection, medical and health care, and other fields in the future.

September 16-18, 2021, on the 23rd China International Optoelectronic Exposition, Nanjing KrystalVision Technology Co. Ltd. (KVT) debuts its new 100-channel hyperspectral camera Protocam-1 and Protocam-2, with the proprietary photonic filter arrays.

The released filter-array-based snapshot hyperspectral camera can be extended to visible and near infrared wavelength range, capable of multispectral (35 channels) and hyperspectral (up to 140 channels) sensing, reaching a rapid acquisition speed of 31.6 cube/s. The self-developed filter-array photonic chips can be mass produced in high precision and cost-effectively. They can be widely adopted in cellphones, industrial and agricultural application, and healthcare areas.
