Wedge prisms introduce a controlled angular deviation. The wedge angle, thin-edge thickness, clear aperture and AR coating should be specified together. The 25.4 mm reference below is a starting point for a custom part, not a stock commitment.
- Beam steering
- Wavefront correction
- Interferometry
- Custom wedge angle
- N-BK7
- AR coating options
- Thin-edge control
