A well logging apparatus includes a probe having a detector assembly. In an exemplary embodiment, the detector assembly includes a scintillator having scintillation a crystal capable of producing light when exposed to gamma rays, a photo-multiplier, and an optical interface positioned between the scintillator and the photo-multiplier. The optical interface optically couples the scintillator and the photo-multiplier. The optical interface includes a gadolinium doped filter glass.
