Full Spectrum Camera

A Full Spectrum Camera is a digital imaging device that has been hardware-modified by removing its factory internal infrared-cut (IR-cut) filter from the sensor plane. This modification expands the sensor’s spectral sensitivity beyond the narrow human visible spectrum (approximately 400nm to 700nm), allowing it to simultaneously record into both the near-ultraviolet band (300nm to 400nm) and the near-infrared band (700nm to 1100nm).

In paranormal research, full spectrum imaging is based on the working hypothesis that spiritual manifestations or residual energy disturbances emit or refract light outside the physiological boundary of human retinas. Paired with dual-frequency UV and 850nm/940nm IR illuminator arrays, these cameras allow field teams to capture environmental shadows, silhouettes, and refractive mists in zero-light conditions without introducing visible flashbulbs.

Operating full spectrum equipment requires disciplined image verification. Unfiltered sensors are hypersensitive to everyday materials: black synthetic fabrics often reflect bright white under infrared illumination, and fine airborne dust particles glow intensely under UV and IR LEDs. Investigators mount full spectrum cameras on stationary tripods to prevent shutter blur and pair them with visible-light control cameras to isolate true multispectral anomalies.
