Miniature Powell Prism
Hobbite's Powell prism is specially designed to generate uniform laser lines. It converts a Gaussian laser beam (characterized by high center intensity and weaker edges) into a linear, uniformly illuminated laser line. Compared with traditional cylindrical lenses, which usually produce "strong edges and weak center", the Powell prism redistributes beam energy through its specially shaped curved surface, ensuring consistent brightness along the entire laser line.

Pentaprism
Prisms
Sunday-optics
Material: BK7, UV fused silica, sapphire, ZnSe, Caf2, Si, Ge, etc. Dimensions: 3mm-380mm Dimensional tolerance [Customer requirements]: +/-0.02mm or Customer requirements
Pentaprisms are widely used in laser levels, imaging, precision systems and optics. Their 90° deviation is independent of prism orientation, making them especially important where orientation cannot be precisely controlled. We manufacture high-precision pentaprisms with customer-specified coatings.
