Abstract
To characterize the spectral and photometric properties of the 16 filters of a commercial Bagolini bar and to determine whether successive filter numbers correspond to a uniform progression of spectral attenuation, illuminance, and interocular contrast. An instrumental spectrophotometric characterization of the 16 filters of a commercial Bagolini bar was performed. Spectral measurements were acquired over the 320-810 nm instrumental range, with the 380-780 nm visible range used for the principal spectral analysis. Spectrophotometric analysis demonstrated non-linear, step-wise changes in the optical properties of successive Bagolini filters. The transmission spectrum peak with increasing filter number shifted from approximately 610 nm to 770 nm. The transmitted light intensity and Weber contrast also exhibited non-uniform, step-wise changes. The 16 filters do not provide a uniformly graded progression of optical attenuation. The measured spectral and photometric transitions provide an optical basis for testable hypotheses concerning non-uniform perceptual responses, but their clinical consequences require psychophysical and clinical validation.
