Kowa LM28LF-48 28mm Fixed Lens for 46mm Sensors with TFL-II Mount 4K Resolution 3.1µm Pixel Support f/2.8 to f/22 Visible Spectrum

*Please note this product is subject to tariff fee*

The Kowa LM28LF-48 is a premium-grade 28mm fixed focal length lens tailored for large-format industrial sensors with a 46mm image circle. Engineered to meet the resolution demands of 4K imaging systems, this lens supports pixel sizes down to 3.1µm with high resolving power, achieving 160 lp/mm at the center and 63 lp/mm at the edge. It delivers a wide horizontal field of view of 424.3mm and vertical FOV of 281.1mm at the minimum focus distance. Low optical distortion (-0.17%) ensures precision image reproduction, essential for machine vision, metrology, and inspection.

This lens features a TFL-II mount for strong mechanical stability, paired with manual focus and iris control (f/2.8–22) for field tuning. Designed for use in visible light (400–800nm) applications, the LM28LF-48 performs consistently in demanding environments with temperatures from -10°C to +50°C. Its compact design (Ø75 x 127mm) and robust housing (500g) make it ideal for integration into automated systems requiring high clarity, low distortion, and consistent focus over a wide field.
