STEMMER IMAGING

The TL series of mainly object side telecentric lenses is designed for line scan applications and is suitable for sensor sizes between  21.4 mm and 60 mm. A large line scan length or matrix size combined with a necessary aperture is an enormous demand on telecentric lenses, which is why Sill recommend a variable iris.

Depending on the mount and back flange distance, line lengths larger than 60 mm can be provided with the appropriate magnification as a custom solution. Different mounts are also available on request.
