BK7 Glass Powell Lens PARAMETER: The Powell lens is a quantum leap forward in line generator performance over the simple cylinder lens. A cylinder lens produces a poorly illuminated line, one limited by the non-uniform, Gaussian laser beam. The Powell lens' rounded roof is in fact a complex two-dimensional aspheric curve that generates a tremendous amount of spherical aberration that redistributes the light along the line; decreasing the light in the central area while increasing the light level at the line's ends. The result is a very uniformly illuminated line used in all manner of machine vision applications; from bio-medical and automobile assembly to chocolate chip cookie production. The Customized Powell Prism resembles a round prism with a curved roof line. The lens is a laser line generator, stretching a narrow laser beam into a uniformly illuminated straight line .

PARAMETER: Rhombic prisms are used to displace a beam laterally without changing its direction. They may be coated to transmit part of the beam and produce two parallel and displaced emerging beams. Can be coated to produce a polarizing beam separator. These prisms are manufactured from either BK7A or Fused Silica. Rhomboid Prism with Coating are supplied uncoated but many coating options are available. Rhomboid prisms are commonly used to displace a laser beam without changing its direction. In imaging applications, rhomboid prisms will displace the optical axis without inverting the image. The lateral displacement is equal to the length of the prism. Specification.

BRD Optical supplies bespoke ball and half-ball lenses to our customers specifications. Ball lenses can be manufactured in quartz to have excellent UV and IR transmission between 185nm to 2000+nm, while sapphire lenses have a higher refractive index allowing a very short fall back length to better facilitate fibre coupling. Custom ball lenses are available in a range of alternative materials such as optical grade glass or even ceramics or IR crystal. Our half ball lenses offer uniform dispersion of light and typically used in LED displays and LED traffic lights.
