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.

Developed by BOSHI Optical Technology, the PL‑1645F‑M12 is a compact fixed‑focus cone lens built around 16mm focal length and F4.5 specifications to serve 1/2" sensor imaging hardware. This M12 mount optical assembly adopts full‑glass four‑element structure, delivering 28.3°FOV alongside 8.5mm image circle to match 1/2" sensor and smaller image sensors for space‑limited board‑level camera optics systems. It reaches 95 percent high relative illumination and realizes low distortion performance with TV distortion value of ‑0.25 percent. Its mechanical back focal length measures 3.65 mm and overall total track length hits 28.65 mm for easy embedding into compact camera modules. Created for machine vision and other embedded imaging scenarios from industrial inspection to biometric identification, the lens from BOSHI Optical Technology tightly controls chief ray angle under 8 degrees to restrain vignetting and color shift when cooperating with mainstream CMOS sensors. It balances resolution, miniaturized dimension and cost efficiency, and fits factory automation, logistics barcode reading and medical imaging devices for stable and authentic image output.
