A capsule-inspection apparatus includes a base (12) and a capsule-receiving tray (10) slidable on the base to cause all of the capsules (14) cradled in pockets (28) formed in the tray to be turned simultaneously about their longitudinal axes to enhance visual inspection of substantially the entire exterior surface of the cradled capsules. An inspection mask (78) is positionable on the tray to permit a user visually to inspect the coating dip line of coated caplets cradled in the tray quickly and easily to determine if the coating dip line is located substantially in the middle of the caplet to ensure that the caplet coating causes the caplet to resemble a two-piece capsule.
