ZEISS Interlock Compact 2.8/21 Lens

Highlights

The ZEISS Interlock Compact 2.8/21 is a compact 21 mm industrial lens designed for large-format area-scan and line-scan imaging. Its Distagon optical design provides an aperture range of f/2.8 to f/22 and a 43 mm image circle suitable for full-frame 36 × 24 mm sensors and large line-scan sensors.

An M42x1 screw mount with an 18 mm flange focal distance positions the lens close to the camera sensor, supporting compact and mechanically stable imaging systems. Precise manual focusing, dedicated fixing screws for focus and aperture, ZEISS T* anti-reflective coating, and robust full-metal construction support demanding industrial applications.
