Anamorphic Prism / APP_APPM
Two anamorphic prisms can be used to change the beam diameter in only one direction. They are used to correct an elliptical beam to circular or to change the ellipticity. Prisms without mounts and three types of mounted prisms with fixed magnification are available.
High transmittance can be obtained at linear polarization (P-polarization) .Three types of anamorphic prisms with anti-reflection coatings are available in the visible, near-infrared, and infrared regions.
Anamorphic prism pair is the beam diameter expansion rate can be changed by adjusting the prism angle. Two prisms are a set of one product.
