Where to Buy Beam Homogenizers

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.

The beam homogenizer from lightsource.tech works in the wavelength range for 350 nm to 2000 nm, or 200 nm to 2000 nm with quartz glass optics. It offers extremely high homogeneity with a deviation of only ±2% and at the same time a transmission of more than 50% of the coupled light. This is made possible by a flyeye condenser, which is equipped with two microlens arrays with 400 lens elements each.

Avantier provides light pipes that can serve as beam homogenizers. These pipes can be either straight or bent at an angle of up to 90°. The light pipes are coated with a five-layer coating that facilitates light transmission while minimizing losses.

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.

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.

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.

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.

Knight Optical offers hexagonal homogenising light pipes which provide uniform illumination from non-uniform polychromatic light sources through the process of total internal reflection. Manufactured from fused silica, these light pipes achieve an approximate 35-40% increase in the output of light. Custom beam homogenisers are available including tapered light pipes.
