N-BK7 Dove Prism for Controlled 180-Degree Image Rotation
This rhombic Dove prism is precision ground and polished to rotate an image by 180 degrees while keeping the transmitted beam path compact. Felix Glass Co., Limited supplies drawing-based dimensions, uncoated parts, and optional high-reflection mirror-coated surfaces for optical alignment, interferometry, laboratory imaging, and instrument integration.

Direct answer
What Does a Dove Prism Do?
A Dove prism inverts an image after one internal reflection. When the prism rotates around its optical axis, the observed image rotates at twice the prism angle. This behavior makes the component useful where image orientation must be changed without adding a multi-element relay assembly.
System performance depends on entrance angle, material, surface quality, prism geometry, and any reflective coating. Final dimensions and tolerances should therefore be reviewed against the optical path and mounting design.

Evaluation points
Why N-BK7 Is Used for Visible-Light Dove Prism Designs
Manufacturing flexibility
Drawing-based dimensions and tolerances can be reviewed for prototypes, replacement parts, and repeat production.
Coating choice
Use an uncoated prism when appropriate, or request a reflective coating based on wavelength and system requirements.
Compact image control
The prism supports image inversion and rotation without requiring a long multi-lens image relay.
Application fit
Where a Rhombic Dove Prism Can Be Integrated
Optical alignment
Image-orientation control in calibration fixtures and compact optical benches.
Interferometry
Optical measurement equipment where image inversion or controlled rotation is part of the system design.
Laboratory imaging
Research imaging paths, beam-rotation platforms, and experimental optical assemblies.
Instrument modules
Miniature sensing, spectroscopy, and custom optical modules with restricted installation space.

Buyer questions
Frequently Asked Questions About Custom Dove Prisms
Does the prism rotate the image by the same angle as the prism?
No. In the standard operating principle, the image rotation is twice the mechanical rotation angle of the Dove prism.
Can the prism be supplied without coating?
Yes. The original product supports an uncoated option as well as an optional high-reflection mirror coating.
Which project details are needed for a quote?
Send the drawing, dimensions, material, wavelength, coating faces, tolerances, quantity, and inspection requirements.
Can dimensions be customized?
Yes. Drawing-based side length and related mechanical requirements can be reviewed for custom production.
