A thermoluminescent reader module having a hardened, durable construction has a casing which houses a filter, a ball lens and detection module. After a thermoluminscent material is heated by a laser diode, the ball lens collects the hemispherical photon emissions. The filter is positioned at the front of the casing to ensure the ball lens receives a predetermined transmittance value of the photons emitted from the thermoluminescent material within a predetermined range of wavelength. The ball lens sends the collected photons via a fiber-optic connection to the detection module. The detection module is connected to a CPU for purposes of processing the detected information. The filter, ball lens and detection module are securely attached and mounted within the interior of the casing.
