Dove prism

An interesting property of the Dove prism is that when it is rotated around its long axis, the image rotates at twice the angle of the prism’s rotation. This feature makes the Dove prism an effective beam rotator, useful in applications such as interferometry, astronomy, and image recognition.Additionally, Dove prisms have an effect on polarized light. For instance, when light incidents at a specific angle onto a Dove prism, the polarization state of the emerging light changes. This polarization effect is significant for signal measurements in certain instruments.In practical use, Dove prisms are typically made from N-BK7 glass, which has high transmission from the visible to the near-infrared spectrum. Uncoated Dove prisms come in various widths, such as 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, and 30 mm. Some models of Dove prisms are also available with anti-reflective coatings, tailored for specific spectral ranges
