General Optics
Powell Lenses
Reshape round, Gaussian intensity distribution laser beams into thin lines with a highly uniform (top-hat) intensity profile along their entire length.
Powell lenses offer a better approach for generating laser lines in applications like machine vision, inspection, and flow cytometry. Coherent supplies both standard and custom Powell lenses covering a wide range of performance and tolerance values.
Coherent Powell Lens Advantages
|
Improved Accuracy Coherent specifies contained power and uniformity for Powell Lenses over 100% of the line length; other manufacturers typically specify performance over the central 80%. And Coherent specifies intensity variation in absolute, rather than average, numbers. Using absolute values guarantees much less intensity variation resulting in better measurement accuracy and signal-to-noise. |
Greater Consistency Specifying performance over the entire line (100%) and in absolute terms also ensures greater unit-to-unit uniformity making it easier for system builders to calibrate their product and maintain consistent performance. |
Volume Production Coherent maintains extensive optical fabrication and coating capabilities, enabling us to produce a Powell Lens that meets your precise needs and to reliably deliver it in any quantity you require. |
