1. A dosimetry device that is connectable to a phototherapy apparatus to apply a targeted dose of UVB light to a treatment area of diseased tissue to determine a minimal blistering dose, the dosimetry device comprising:
a tubular housing having a sidewall with an outer surface and an inner surface extending along an axis between a first end and a second end, which is spaced from the first end, the housing defining a single cavity extending contiguously along the axis about the inner surface of the sidewall between a single opening at the first end and a single opening at a second end, the cavity being devoid of a light source arranged therein, and the first end of the sidewall configured to be releasably connected directly to a distal end of a hand piece of the phototherapy apparatus that is configured to distribute the targeted dose of the UVB light through the housing to the treatment area of the diseased tissue to determine the minimal blistering dose; and
a single optical matrix including a plurality of transmissive regions that include at least a first transmissive region and a second transmissive region that are at least one of connected to and formed within the housing at the second end of the sidewall of the housing,
wherein at least one of the transmissive regions includes at least one of a metallic, multi-dielectric and a dielectric coating that is configured to reduce an intensity of the UVB light passing through the housing and the at least one of the transmissive regions, and
wherein each of the plurality of light transmissive regions each permits a different transmission of the UVB light to pass therethrough and contact the treatment area of the diseased skin.
