Beschreibung
This 12mm 5MP low distortion M12 fixed focal machine vision lens is a high-precision industrial optical component optimized for 1/2”,1/1.8”,2/3” image sensors, widely recognized as a premium M12 industrial lens for machine vision and CCTV security systems. Adopting 6-group glass plus IR filter optical layout and F2.8 fixed aperture design, it balances stable light intake, low distortion and high transmittance (>82.5%), solving blurring, image deformation and infrared color shift pain points common on generic M12 lenses. It fits mainstream industrial and surveillance cameras, ideal for medium-distance low-distortion visual capture.
Core Product Advantages
- Precision 12mm FOV Calibration Eliminates View Deviation: Tuned 37° diagonal,30° horizontal,23° vertical FOV for 1/2” sensor; avoids uneven framing and over/under view blind spots that cheap fixed focal lenses suffer during on-site debugging.
- <-1.5% Ultra-Low Distortion Guarantees Edge Image Integrity: Strict low distortion design fixes barrel distortion defect, no peripheral image stretch, ideal for dimensional detection requiring full-frame accurate imaging, different from high-distortion ordinary CCTV lenses.
- High IR Transmittance & IR Correction Fixes Night Color Cast: Built-in IR filter with ≥82.5% relative transmittance, correct IR aberration to remove reddish night image drift, saves customers extra IR-cut filter procurement cost.
- Standard M12 Fixed Structure Reduces Assembly Modification Cost: Fixed F2.8 aperture + fixed iris + M12×0.5 mount, plug-and-play installation without lens housing refitting, shortens camera module production cycle vs customized non-standard lenses.

FAQs
Q: Can this M12 low distortion lens work on 1/1.8” and 2/3” sensors besides 1/2”?
A: Yes, the optical design covers three sensor formats (1/2″,1/1.8″,2/3″); actual FOV will shrink moderately on larger sensors, no vignetting occurs under F2.8 aperture.
Q: Is extra IR filter needed for night infrared monitoring?
A: No, 6G+IRF built-in IR filter realizes IR correction, ≥82.5% transmittance ensures clear day & night imaging without additional IR accessory purchase.
Q: Can this fixed focal lens change focal length manually?
A: It belongs to fixed focal M12 lens with fixed 12mm focal length and fixed iris; focal length adjustment is unavailable, ideal for fixed-position monitoring & inspection scenes.
Q: What’s the advantage of <-1.5% low distortion vs regular M12 CCTV lenses?
A: Ultra-low distortion prevents edge pixel deformation, critical for machine vision dimensional measurement where image accuracy directly impacts detection result precision.
