• Standard, OEM or custom
• Sinusoidal, binary, or other grating profiles
• Photoresist on silica, etched silica, or other substrate materials available
• High diffraction efficiency
• Uniform intensity patterns
• Operating wavelengths 250 nm to 1550 nm

Coherent offers a wide selection of standard and custom diffractive optical elements (DOEs). These DOEs transform a single laser beam into various simple or complex structured light patterns, as illustrated below. In "dot" patterns, each of the several outgoing beams carries the same power. In "line" patterns, the lines are of uniform intensity.

Our DOEs can be fabricated in photoresist (for use with lower power lasers). Alternately, they can be etched in fused silica (for use with high-power or UV applications). Each individual DOE is tested to ensure repeatable and reliable results.
