Prism Mount, 0.25 to 1.00 in., ±5 °, M4

The 9411-M Prism-Beamsplitter mount offers three orthogonal axes of rotation. Designed for intuitive alignment, the rotation point is located under the center of the mounting plate so that you get minimal translation during adjustments. Our novel spring clamp (simply press the post down to hold your cube) means you don't need to use messy double-stick tape or wax. M4 Thread.
