Where to Buy Beam Homogenizers

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.

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 m, 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.

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.

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.

Focuslight Technologies offers 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.

PowerPhotonic manufacture high quality beam homogenisers for single and multimode beams. These refractive homogenisers create a controlled, uniform profile that can withstand very high powers due to the LIDT of the fused silica used in production. Due to PowerPhotonic’s unique manufacturing process, customisation of the shape size and profile of the output beam is easy.
