FJW Find -R- Scope (For Parts / Not Working). Unfortunately I’m not Sure What’s Wrong might be a wire or a battery. Custom f/1.0 Infragon Lens. The FJW Optical Systems 84499A Find-R-Scope Infrared Viewer is a self-contained, hand-held infrared viewer operating in the near-infrared region of the spectrum. A high-resolution image converter tube, and high voltage power supply combine with proprietary Infragon objective lens and other precision optics to permit a clear view of objects or images which cannot otherwise be seen by the naked eye. The Find-R-Scope has a wide variety of applications in many different industries. These applications are further expanded by taking advantage of the available accessories. The optional close-up lens allows for viewing within 2 to align and verify fiber optic sources. The infrared filters increase the signal-to-noise ratio by blocking visible light while inspecting infrared emitting diodes, aligning laser systems and examining art and other historic or legal documents. Other applications include low light surveillance, biological research, electrical maintenance, hot-spot detection, clinical medicine, and viewing in photographic darkrooms.
