Devices and methods for well logging using a diamond window assembly are provided. A method according to the disclosure includes placing a downhole tool in a wellbore in a geological formation and compressing a window assembly in the downhole tool against the geological formation. The window assembly may include a polycrystalline diamond compound material fused with a monocrystalline diamond window that holds the monocrystalline diamond window in place, despite being compressed against the geological formation. First photonic radiation may be emitted through the monocrystalline diamond window onto the geological formation. Second photonic radiation may be detected through the monocrystalline diamond window. This second photonic radiation may derive from interactions between the first photonic radiation and the geological formation. As such, the second photonic radiation may carry information relating to the composition of the geological formation (e.g., the presence or absence of hydrocarbons). |
