Field of view (width × height) of the 14 mm lens by sensor format and working distance
Sensor format	At 56 mm	At 150 mm	At 300 mm	At 1000 mm
640 × 480, 17 µm10.88 × 8.16 mm	43.5 × 32.6 mm	117 × 87.4 mm	233 × 175 mm	777 × 583 mm

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.

Questions about the LS-SWL-0005

Answered from this model's printed specifications and our fit tests. Calculated figures say “about”.

What field of view does the LS-SWL-0005 give at 150 mm?

About 117 x 87.4 mm on a 640 × 480, 17 µm sensor, about 777 x 583 mm at 1000 mm (calculated: sensor size x distance / 14 mm focal length).

What sensor size is the LS-SWL-0005 made for?

Image circle: dia. 13.6 mm, calculated from the 640 x 480 detector at 17 micron pixel pitch.

How does the LS-SWL-0005 differ from LS-SWL-0051?

Compared with LS-SWL-0051: aperture F1.2 here, F1 there; sensor 640 x 480 17 µm here, 1024 x 768 14 µm there.

Engineering guides picked for the LS-SWL-0005: how to choose it, set it up and get a better image.

All guides

Thermal camera NETD and lens choice for process monitoringNETD is the smallest temperature difference a thermal camera can separate from its own noise, quoted at a scene temperature and lens F-number: 40 mK at F/1.0 roughly doubles at F/1.4. Machine vision lens calculator: focal length and field of viewDivide the sensor width by the field of view to get the magnification, then multiply the working distance by m / (1 + m) for the focal length.
