The optional Trinocular Attachment TH-2 is actually a complete trinocular head to replace the monocular head to make it possible to use the microscope for photography directly via the third camera position. To attach a dSLR you would also need to purchase the SLR Camera Adapter CA-5 and a camera specific T-ring.
To make it complete, you're also advised to purchase additional eyepieces as the 500LM only comes with a singular set of eyepieces...
