• Square Lens and Fly’s Eye Configurations
• Precision Fused Silica Substrates
Microlens arrays are useful for homogenizing a variety of modern light emitters from line-narrowed excimer
lasers to high power LEDs. Microlenses are well suited for applications that require high efficiency and nongaussian
uniformity. All arrays are constructed from UV-grade fused silica, offering exceptional performance
from 193 nm to 2,5 μm. The arrays are manufactured using standard semiconductor techniques, yielding very
accurate shaping of the lens profile and precise positioning of the lenses within an array. A single array can be
used to generate a line and a pair of crossed arrays will generate a square flat top. We offer our arrays in two
configurations.
Square Microlens Arrays
Our square arrays are available in a standard 10 x 10 mm configuration in a variety of lens pitch and focal
length options. Square microlenses are commonly used for beam homogenization and shaping, yielding spot
patterns or a square flat-top pattern. The lenses feature a high fill factor which eliminates zero-order hot spots
in the illuminated field. Square lenses are often used in pairs, in conjunction with a PCX lens (see above). Typical
applications include welding, drilling, laser ablation, and fiber coupling.
Fly’s Eye Condenser Arrays
Our fly’s eye condensers are available in 5 and 10 mm square configurations, and are designed for flat-top and
line generation. The condensers are a monolithic assembly of dual-surface cylindrical microlenses, creating
condensers which are completely free of adjustment. These microlenses are commonly used in applications
requiring a large illuminated field with a short working distance, such as medical laser use, solar simulation,
UV-curing, semiconductor instrumentation and fluorescence microscopy.

Gradient Index (GRIN) Rod Lenses
• Ideal for Fiber Coupling
• Comparable Performance to Conventional Aspherical Singlets
• Multiple Sizes and Wavelength Options
Gradient Index (GRIN) lenses feature plane optical surfaces and achieve focus via a continuous change of the
refractive index within the lens material. By eliminating complex geometries (such as aspherical surface figures)
and carefully designing the lenses for specific working distances, these micro lenses are quite easy to handle
and integrate into optical systems.
Our GRIN lenses are designed to provide a 0,55 numerical aperture, and are available in 2 working distance
options. Lenses with a 0 mm working distance are ideal for collimation of single and multi-mode optical fibers
and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing
applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are
available with a small working distance as well. Each lens is available uncoated (approximately 12% reflection
loss), or with a BBAR coating option for Ravg < 0,5% at the design wavelength. Substrate: Alumosilicate Glass Embedded with Silver Ions
