Where to Buy Beam Homogenizers

PowerPhotonic design and manufacture beam homogenizers made of fused silica for use with single mode beams and multimode beams. Multi-mode homogenizers maintain a Gaussian beam profile. However, PowerPhotonic can also design and manufacture homogenizers that change the beam profile and shape e.g. from Gaussian to top hat or to supergaussian or other custom shapes.

Shanghai Optics offers light pipes which can be used as beam homogenizers. They can be straight or bent pipes with a bending angle up to 90°. A five-layer coating ensures light transmission with low losses.

Focuslight Technologies offers LIMO beam homogenizers that can handle a wide range of field geometries and beam shapes – top hat, rectangular, square and lines – and are suitable for many different laser sources (e.g., excimer laser, solid-state laser, diode laser).

Features:

• extraordinary homogeneity (up to 1% non-uniformity)
• high NA
• high fill factor
• retention of polarization
• optical efficiency up to 90 %
• low cost

They are manufactured from high-quality materials, e.g., fused silica or CaF₂. Customized freeform surfaces with highest precision on different wafer sizes (up to 300 mm) are also available.

IRD specializes in high-precision light homogenizers and light pipes. IRD manufactures traditional square and round homogenizers, as well as more exotic rectangular, hexagonal, and octagonal homogenizers, including straight and tapered designs. Their designs are optimized based upon your specific needs and requirements; typical materials include, but are not limited to, fused silica, nBK7, and sapphire.

As the name suggests, beam homogenisers are used to produce uniform beam profiles. Used for the most forward-thinking laser-based applications, our beam homogeniser range is only available in a custom-made option to meet the precise needs of each application. Commonly specified in BK7 (or equivalent) and UV-grade fused silica substrates, Knight Optical's custom-made homogenising rods are also available with rod holders for seamless integration.

Edmund Optics offers the world’s largest inventory of off-the-shelf optical components. The majority of Edmund Optics’ light pipes are hexagonal in shape, which leads to 35% less light loss than for comparable square light pipes. Fused silica light pipe homogenizing rods are ideal for applications utilizing UV LED light sources. Tapered light pipe homogenizing rods offer several magnification options, including 2× or 3×. Edmund Optics offers light pipe mounts for either tapered or hexagonal light pipes, designed to offer easy system integration solutions, or to ease handling.
