JSD3936

Product Overview

The JSD3936 is a specialized M12 S-Mount fixed focal lens, precision-engineered for 1/2.5-inch image sensors. Distinguished by its outstanding optical correction, this lens features a 4.18mm focal length and an F3.0 aperture, delivering a natural 83° field of view. Its defining characteristic is an ultra-low distortion rate of less than 0.45%, ensuring virtually zero geometrical deformation. This makes it the ultimate choice for precision machine vision, text recognition (OCR), and biometric scanning where image fidelity and straight-line accuracy are non-negotiable.

Key Features & Benefits

High-Definition 5MP Resolution:Designed to resolve high-density pixels, delivering sharp, 5MP imaging suitable for detailed inspection and high-accuracy recognition algorithms.

Extreme Low Distortion (<0.45%):Features superior optical engineering that reduces distortion to under 0.45%. This rectilinear performance ensures that the captured image perfectly matches the physical object, eliminating the "barrel" effect common in standard lenses.

Optimized for 1/2.5" Sensors:Custom-calibrated for 1/2.5" sensor formats, featuring a precision image circle that ensures edge-to-edge sharpness without vignetting.

Standard 83° Field of View:Provides a focused 83° viewing angle, offering a balanced perspective ideal for capturing specific targets or subjects without the perspective distortion of wide-angle lenses.

Precision Optical Design:The F3.0 aperture and multi-element glass construction are optimized for depth of field and contrast, critical for scanning documents and static objects.

Compact & Industrial Build:Equipped with a standard M12x0.5 thread and a Total Track Length (TTL) of 21.5mm, designed for easy integration into handheld scanners, industrial cameras, and compact detection devices.
