Tereos 50 and Tereos 50 OM have been developed as a Clip-On Thermal Scopes for use with RGW90, which comes with optical sight EOS1.5x. The products work by overlaying LWIR thermal image over VIS image, in front of optical sight. Overlaying is done by beam splitter. They have optical magnification 1x.

Tereos 50 can be used as an independent device. In this case, it can be used with zoom up to 2x.

Tereos 50OM can be used as an independent device. In this case, it can be used with digital zoom.
