Weighing only 1.5 lbs and measuring only 14" long, this portable hand-held illuminated magnifier utilizes a 3.5" 5-diopter optical grade lens and your choice of a white or ultraviolet ring light at the base, providing ample illumination for examining latent prints or small fluorescing evidence such as trace evidence. The long 8-foot power cable allows you the freedom to roam about the crime scene.
