Dicyanin dye, when incorporated into glass, creates a unique optical filter historically associated with near-infrared (NIR) photography and certain spectroscopic applications. This type of glass selectively transmits light in the red and NIR spectral regions, while absorbing visible light at shorter wavelengths. An example of its historical use includes purported ability to photograph auras, though…
Dicyanin dye, when applied to optical lenses, purportedly allows the wearer to perceive near-infrared radiation, a portion of the electromagnetic spectrum invisible to the unaided human eye. This claim initially arose in the early 20th century, with anecdotal accounts suggesting applications in scientific fields like astronomy and medicine. However, rigorous scientific evidence confirming these purported…
