GCL-040201 Wedge Prisms
GCL-04 Wedge Prisms
An optical element has plane-inclined surface. Wedge prisms are used as small beam steering elements in optical systems. By combining two wedges of equal power (equal wedge angle) in near contact and independently rotating them, a ray passing through the combination can be steered in any direction within a narrow cone.
