Off-axis parabolic mirrors are finite conjugate focusing mirrors that image at a set angle. They have fixed conjugate images and path length of the object. The light passing through a aspherical mirror can be parallel to the optical axis of the parallel light, completely converging to the focal point. The spherical...
Penta Prism Penta Prism containing two reflecting surfaces at 45 to each other, and two refracting faces perpendicular to the entering and emerging beams. It provides a 90° deviation of the beam from the focus plane. supply custom Penta Prism, including N-BK7 Penta Prism and UV Fused Silica Penta Prism for use in the...
Amisi roof prism is named after the inventor Italian astronomer Giovanni amisi. It is a reflective optical prism that can invert and deflect the image by 90 °. He is often used in the eyepiece of a telescope as a system for image erection. The shape of this element is like a standard right angle prism attached to the...
The roof surface of the prism is sometimes coated with optical coating to become the surface of the mirror, which makes the prism not limited to the critical angle of total reflection and can accept incident light at a large angle. Do not confuse the non dispersive Amish roof prism with the dispersive Amish prism....
The wedge angle of wedge prism (fine annealed K9 optical glass) and antireflection film on the back can reduce the ghost image interference reflected on the back surface. High precision substrate ensures the accuracy of reflected and transmitted light wavefront. We provide a variety of wedge prisms and antireflective...
