-=====Aligning the DBR Laser Module=====
-The module should not need adjustments, but if necessary the following procedure can be used to fine tune the beam positioning.
-  - Loosen the three locking screws on the back of the DBR module ½ turn past the crack point.
-  - With a 0.050" Allen driver, adjust the vertical adjustment setscrew on the top of the DBR housing to level the beam.
-  - Adjust the horizontal adjustment 4-40 set screw on the left side of the DBR housing (See <imgref DBR_lock_screws>).
-  - Alternatively, use the spectroscopy module as a beam target.  Place the spectroscopy module as far down the table as possible, bolt it down, and center the beam to the input hole.
-  - Gently retighten the three locking screws.
