Spectral responsivities, non-linearities, noise, dark signals and stabilities are traits of the sensors. For the measurement of irradiance and exposure an input optic is placed in front of the sensor, i.e. fiber bundles, transmitting or r

These geometrical and imaging factors challenge the task of attempting to accurately measure the photobiologically significant exposure of the cornea, lens and retina to

The Mark IV provides uniform illumination (± 15%) over 0.5 m. at 60 cm utilizing non-spatial collimation with 20–100 µ pulses of UVB/UVA. The optically coated reflectors serve as highly effective bandpass filter

https://doi.org/10.1007/978-3-476-02890-7 regulation of melanogenesis is incompletely understood, evidence suggests that UV-induced DNA is at least one of the initial signals that stimulates melanogenesis in response to UV irradiation.. First, the action spectrum for the tanning response in human skin is essentially the same as that for th

Some studies have evaluated the photoprotective role of facultative pigmentation using erythema and epidermal DNA photodamage caused by a single UVR exposur
