CHANCCTV expands ToF lens lineup for facial recognition and AI projects

Fuzhou ChuangAn Optics says its time-of-flight lens portfolio is built to support facial recognition, gesture control, depth sensing, and other AI vision projects. The company is emphasizing model-level specs, sample testing, and customization as engineering teams look to match optics with 940 nm ToF sensor systems.

Why it matters: - Facial recognition and AI vision systems depend on stable depth data at the optical level, not just software. - Matching a ToF lens to the sensor, wavelength, field of view, and operating conditions affects depth accuracy, spoof resistance, and recognition reliability. - For engineering teams, verifiable lens specs and sample testing can shorten the path from concept to prototype.

What happened: - Fuzhou ChuangAn Optics Co., Ltd. highlighted its CHANCCTV ToF lens portfolio for facial recognition and artificial intelligence projects. - The lineup covers 1/2-inch and 1/3-inch sensor formats, compact M12 mounts, multiple focal lengths, and 940 nm bandpass options. - The company says the lenses have been used in depth measurement, skeleton recognition, motion capture, and automotive sensing. - CHANCCTV said it supports buyers with model-level specifications, application guidance, and customization for sensor integration and calibration. - The company directed readers to the official website for product inquiries and custom optical consultations.

The details: - CHANCCTV said its ToF lens development focuses on sensor format compatibility, focal length, aperture, horizontal field of view, wavelength transmission, and thermal stability. - The current product lineup supports 1/2-inch and 1/3-inch sensors and sensing resolutions up to 5 MP. - Focal lengths range from 1.62 mm to 7.76 mm. - Horizontal field of view options range from about 48° to 109°. - The company said these M12 ToF lens configurations are aimed at different working distances and depth-camera designs. - CHANCCTV said final depth accuracy depends on the lens, sensor, illuminator, calibration, and processing algorithms working together. - For 940 nm systems, CHANCCTV pointed to the CH3731C as a model-level example. - The CH3731C is built for 1/3-inch sensors, has a 3.3 mm focal length, an F1.1 aperture, a 74.5° HFOV, a BP940 nm filter, and an M12 mount. - The CH3731C is rated for operating temperatures from -20°C to 85°C. - CHANCCTV said project teams still need module-level testing to confirm working range, depth accuracy, modulation frequency compatibility, and eye-safety standards. - The company said its application context includes iris recognition, smart homes, VR/AR, automotive ADAS, CCTV, and surveillance. - CHANCCTV said its product development and manufacturing focus dates to 2010. - The company said it offers selectable models, test samples, datasheets, and system test indicators for evaluation. - CHANCCTV said standard components can be ordered with one-piece samples and no minimum order quantity. - Stock samples are typically available in about 3 days, and the company said it responds to inquiries within 24 hours.

Between the lines: - The pitch is less about a single lens and more about reducing integration risk for depth-sensing systems. - CHANCCTV is positioning optical validation as the first hurdle before algorithm tuning and full module calibration. - The emphasis on samples, datasheets, and custom parameters suggests the company is targeting engineering teams rather than end users.

What's next: - Buyers are expected to submit sensor model details, active area dimensions, illumination wavelength, working range, target FOV, aperture, mount type, temperature range, depth accuracy goals, calibration method, and production volume. - CHANCCTV says engineering teams can use sample testing and physical depth validation before committing to larger builds. - The company is looking to convert specification screening into custom lens selection and prototype verification.
