The lenses are being used on passenger rolling stock with the focal range depending on viewing lines. The units are functioning from compact Sanyo colour cameras and the client reports that the lenses are producing excellent image quality in both low light conditions and under harsh fluorescent strips. Images are stored using an MPEG4 capture board assembled by Madrid-based Sato Electronica who have specified and implemented the project.

The 3.0~8.5mm unit being used predominantly in the carriages is 1/3” format and has an iris range of F1.0-C. Iris drive is manual and the lens has a CS mount. Horizontal angle of view (1/3”) is 90.5°-33.6° and (1/4”) 67.2°-25.2°. Minimum object distance is 0.2m and dimensions (mm) are ø35 x 46. The lens weighs 51 gs.
