Abstract
A portable thermal imager has a shock-absorbing lens mount that minimizes the transfer of the impact forces to the fragile lens. The lens of the portable thermal imager is encased within a circumferential grommet and then received in a cavity defined by the housing such that the lens is essentially suspended within the cavity. Since the lens is essentially suspended, little or no force is translated to the lens if the thermal imager is dropped or otherwise impacted.
Claims5
A portable thermal imager, comprising:
- a housing;
- a sensor contained within said housing that reacts to infrared radiation, converting sensed radiation into a visible thermal image;
- a video display secured to said housing and operably connected to said sensor for displaying said visible thermal image;
- and
- a lens that focuses infrared radiation onto said sensor, said lens being encased within a circumferential grommet and received in a cavity bounded by a rim extending from said housing, said grommet being compressed against an internal wall of said rim.
