From March 17th to 19th, 2021, Nanjing Kanshijie Intelligent Technology Co., Ltd. (hereinafter referred to as Nanjing Kanshijie) participated in the 16th Messe und Kongress光学 Exhibition in Shanghai, China. The Spec, a miniature spectrometer based on the newly developed 100-channel filter array chip, made its debut at this highly influential comprehensive exhibition in the field of optoelectronics.

Miniature spectrometer manufactured based on the filter array process, with the ability to extend to different bands such as visible light (VIS) and near-infrared (NIR), featuring two types of specifications: spatial light type and fiber type, with accuracy up to 0.2nm, linearity >0.95; dynamic range 1000:1; signal-to-noise ratio >100.

At the same time, the self-developed array filtering chip has the advantages of high precision, low cost, and mass production, and can be widely used in color recognition, industrial inspection, environmental protection inspection, food safety and other fields in the future.

Nanjing KrystalVision Technology Releases A New Micro Spectrograph Product With >100 Channels

March 17-19, 2021 on the 16th LASER World of Photonics China, Shanghai, Nanjing KrystalVision Technology Ltd. (KVT) debuts a new filter-array-based chip-scale spectrograph with over 100 spectral channels.

The released micro spectrograph is based on filter arrays and can be conveniently extended to visible (VIS) and near infrared (IR) wavelength range. The spectrographs are designed in two configurations, including free-space sensing and fiber-coupled sensing. The products achieve an accuracy <0.2 nm, a linearity>0.95, a dynamic range >1000:1, and a signal-to-noise ratio (SNR) >100.

The filter-array photonic chips can be mass produced in high precision and cost-effectively and are promised to be widely adopted in color calibration, environment protection, and food safety applications.
