Lummer Brodhun Photometer
High-Transmission Lummer-Brodhun Cube: Utilizes two optically matched right-angled glass prisms with a precision-ground central contact area, creating a concentric visual field for seamless brightness matching with near-zero parallax error.
Micrometer-Controlled Positioning: Integrated with a heavy-duty graduated optical bench and rack-and-pinion drive, providing the sub-millimeter displacement accuracy required to strictly adhere to the inverse-square law during sensitive intensity evaluations.
