Optical wedge prism GCL-04 series

BK7

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. • Dimension Tolerance: +0.0/-0.15 • Flatness: λ/4~λ • Surface Quality: 60-40 scratch-dig • Clear Aperture: 90% surface area • Coatings: 1/4 wave MgF2 coating at 550nm for 0° angle of incidence • Beam Deviation(e˚): ≈(n*-1)·α˚ n*: Index of the material
