Ergonomy
Ergonomic, light and small, the VISION dosimeter does not affect the user’s activity and view. It is made from a plastic resistant to twisting.
The dosimeter is flexible and can be placed close to the eye, providing a more accurate measurement of the lens of eye dose. The VISION lens of the eye dosimeter is to be worn in conjunction with radiation safety glasses or safety shields, with the detector behind the shielding.
If the field is uniform or shielding is not present, the VISION dosimeter should be placed as close to the eye as possible without interfering with the field of view.
The cap with titanium oxide particles is laser etched for permanent marking and identification. This also allows for easy cleaning.
