Thin-lens approximation: field of view ≈ sensor size × working distance ÷ focal length, with the distance measured to the front of the lens; closest to reality when the distance is many times the focal length. Sensor sizes are typical for each optical format.

Which cameras does the LS-SWL-0243 cover?

Its image circle (about 17.5 mm) covers these fit-tested cameras: LS-CMR-0551 (3/4", 0.3 MP), LS-CMR-0525 (1/1.4", 5.2 MP), LS-CMR-0497 (1/2", 1.3 MP) and LS-CMR-0548 (1/1.4", 5.2 MP).

What field of view does the LS-SWL-0243 give at 500 mm?

About 141 x 103 mm on a 1.1" sensor, about 564 x 412 mm at 2000 mm (calculated: sensor size x distance / 50 mm focal length).

Does the LS-SWL-0243 need an adapter for C-mount or CS-mount cameras?

No for a C-mount camera: it is a C-mount lens. Yes for a CS-mount camera: fit a 5 mm C-CS adapter ring such as LS-LXR-0266.

What sensor size is the LS-SWL-0243 made for?

The sensor format is 1.1".
