In application scenarios such as all-weather security monitoring, Intelligent Transportation Systems (ITS), and night vision inspections, the Sony IMX462 has become a star sensor model in the market, thanks to its exceptional infrared sensitivity powered by STARVIS 2 technology. This sensor exhibits extremely high quantum efficiency in the near-infrared (NIR) spectrum from 850nm to 940nm.

However, many engineers encounter a common pain point when pairing it with M12 lenses: "sharp images during the day, but out-of-focus images at night when the IR illuminator is turned on." The core solution to this issue lies in selecting a true IR-corrected (infrared confocal) lens.

1. Core Technical Logic: What is an IR-Corrected Lens?

Standard optical glass has different refractive indices for different wavelengths of light. This causes an axial position deviation—known as axial chromatic aberration—between the focal points of visible light (daytime) and infrared light (nighttime).

Standard M12 Lenses: When the IR illuminator turns on at night, the focal point shifts backward, causing the 1080p HD image to become completely blurred.

IR-Corrected M12 Lenses: By incorporating Extra-low Dispersion (ED) glass and specialized optical structural designs, the focal planes of both visible light (400–650nm) and near-infrared light (850–940nm) are maintained at the exact same position, eliminating day-to-night focus shift.

To fully leverage the starlight-level and infrared advantages of the IMX462, strict adherence to high-standard optical parameters is required during lens selection. Below is the comprehensive technical specification matching table:

3. Lens Solution Expansion: The Hardcore Capabilities of JSD Optical

Addressing the stringent demands of the Sony IMX462 for day/night IR correction and ultra-large apertures, Shenzhen Jinghuadu Optoelectronics Co., Ltd. (JSD Optical) has delivered an ideal production-grade solution backed by deep technical expertise.

A. Outstanding Optical R&D Capabilities

JSD Optical boasts an experienced optical design team specializing in the precise matching of Chief Ray Angle (CRA) and spectral response curves for mainstream sensors. Tailored for the IMX462, the JSD R&D team successfully overcame the technical bottleneck of combining an F1.0 ultra-large aperture with a 400–950nm ultra-wideband day/night IR correction. Through a precision aspherical glass lens element combination design, the system ensures consistently sharp imagery during all-weather transitions, eliminating the need for frequent backend motor focus adjustments.

B. Cutting-Edge Manufacturing Prowess

As a leading lens supplier in the industry, JSD Optical operates a massive Class 10,000 modern dust-free workshop and automated production lines. The assembly of 4K and starlight-level M12 lenses demands micron-level precision for lens centering. By introducing internationally advanced processing equipment and precision optical testing instruments (such as automated MTF testers), JSD Optical ensures that every mass-produced IR-corrected lens exhibits exceptional consistency, perfectly meeting rigorous industrial-grade and security-grade quality control standards.

C. Trusted Endorsement from Global Industry Giants

JSD Optical's products are exported to major domestic and international markets, including France, the United States, Germany, and Japan. Whether in complex outdoor intelligent transportation monitoring or high-precision industrial machine vision, the synergistic performance of JSD lenses paired with sensor models from Sony, OmniVision, and Onsemi has been thoroughly validated over the long term by numerous world-renowned enterprises.

4. Seamless Day-and-Night Synergy Unleashes True Starlight Performance

The Sony IMX462 is a premier night vision asset in total darkness. However, it can only achieve true all-weather precision capture and data delivery when paired with an IR-corrected M12 lens that refuses to compromise on resolving power, even at the 940nm band. Choosing the JSD Optical solution provides you with one-stop, closed-loop support spanning from optical design to large-scale mass production.
