Model 85720 Camera Includes On-Camera Electronic Viewfinder. Operates in the Visible , Near IR, and Short-Wave IR Spectrums (400–1800 nm). Features On-Board Electronic Viewfinder, Standard Monochromatic (B&W) Video Output. Camera includes Power Supply, 25 mm ƒ:1.4 Lens and Carrying Case. (Camera above is shown with standard lens and viewfinder.)

The FIND-R-SCOPE® 85720 is a Visible to Short-Wavelength Infrared camera operating in the 400-1800nm region of the electromagnetic spectrum. The camera includes an On-Board Electronic Viewfinder. These cameras utilize proven infrared viewing technology. The high resolution infrared vidicon tube CCTV camera generates a clear view of objects, sources & images which cannot otherwise be seen with the naked eye.

The camera can be easily mounted on a standard tripod. No external processing box is required. The video image can be viewed on any monitor that accepts a video input. The camera video output can be fed directly to a video recorder, or to a computer via a standard image acquisition card (frame grabber card).

Alignment of Beams from Invisible Sources Use camera to align beams from invisible sources such as lasers and LEDs emitting in the invisible Near-IR and SWIR regions.

Light Intensity in the Near-Infrared and SWIR regions View light intensity of infrared light sources such as infrared LEDs, and transmission characteristics of optical fibers.

Surveillance and Covert Observation Use with IR light source for surveillance in low/no visible light and darkrooms conditions.

Microscopy Camera can be mounted to a microscope for applications such as detecting internal IC defects and biomedical observations.

External Processing After capturing video via a video capture device, third party software can be utilized for further image processing.

Biological Detect unseen bruising in fruits. See indications of plant diseases invisible to the naked eye. Detect the presence of small insects not apparent due to small size and protective coloration.

Document Examination and Forgery Detection Infrared viewers can help with deciphering of erased markings, detection of alterations or overwriting, restoration on certain inks removed by abrasion or bleaching and other forgery methods.

Electronic Industry Applications Detect stress patterns in silicon crystals and various semiconductor wafer materials. Study of gaseous lasers.

Industrial Applications Detect flaws not visible to the naked eye. Infrared penetrates many dyes and pigments used in textiles and various paints and coatings.

Fine Art Analysis and Authentication Using Infrared Refrectography can allow viewers to look beneath the surface of a painting or look through years of soot and dust accumulation and to see beneath layers of darkened varnish or over glazing. This often allows the conservator to view under drawings and modifications that are invisible to the naked eye.
