20 x 20mm, 800µm Pitch, 0.3° Div., Cyl. Microlens Array VIS-NIR

Product Details Generate Non-Gaussian Line Patterns Ideal for Light Homogenization Excellent Performance from 193nm – 2.5μm Cylindrical Microlens Arrays are used to homogenize a variety of light sources, including lasers or high power LEDs. Unlike Square Microlens Arrays , which generate spot patterns, Cylindrical Microlens Arrays yield non-gaussian line patterns, and are ideal for welding, drilling, or laser ablation applications from the UV to IR. Cylindrical Microlens Arrays are available uncoated, VIS-NIR, or UV-NIR coated, including options with lenses on a single side for line generation applications or double-sided (with cross-oriented lenses) for beam homogenisation. Additionally, these lenses can be used as fast axis collimators.
