xThe PL-2445D-M9 is a compact fixed-focal lens engineered by BOSHI Optical Technology for high-resolution industrial imaging. With a 24mm focal length and F/4.5 aperture, this lens delivers exceptional clarity and consistent brightness across a 1/2.5" sensor, covering a maximum image circle of Ø7.4mm. Its all-glass (3-element) construction ensures thermal stability and superior transmission, while the M9 thread mount (P0.35) provides reliable mechanical integration into space‑constrained systems. The lens offers a narrow field of view (16.7° diagonal) ideal for long‑distance inspection, with a TV distortion of merely -0.05% and relative illumination of 97.0% – values that guarantee faithful geometric reproduction and minimal vignetting. The chief ray angle (CRA) stays below 6.6°, ensuring excellent compatibility with modern sensor micro‑lens arrays. Whether deployed in automated optical inspection, precision metrology, or surveillance, this 24mm focal length lens from BOSHI Optical Technology maintains sharpness from center to edge. Its robust optical design supports consistent performance under varying temperatures, making it a dependable choice for OEM integrators who demand repeatable imaging quality without compromising on size or cost.
