Laser Optical Assemblies: Beam Expanders & Attenuators

23 Oct 2023

At EKSMA Optics, we deliver new solutions by covering the entire value chain from the initial optical system design and manufacturing of custom-tailored precision components to the final assembly.

Our expertise:

• Design - optical, opto-mechanical, electro-optical
• Manufacturing - cleanroom assembly: prototype and volume quantities
• Testing - advanced metrology and performance testing

We invite you to discover our standard product range, including beam expanders, f-theta lenses, and laser power attenuators, and to contact EKSMA Optics as your partner for custom precision optics and optical assemblies.

Fixed Ratio Beam Expanders for High Power Lasers – designed for short pulse (ns/ps/fs) laser applications, these beam expanders incorporate precision thin lenses with high-LIDT anti-reflection coatings and robust opto-mechanics, featuring sliding lens design.

• IBS AR-coated for Yb:KGW/KYW and Nd:YAG laser wavelengths
• Low GDD: relative pulse broadening <20%
• Fixed magnifications: 1.5X to 10X
• High total transmission: >99%

Compact Variable Laser Power Attenuators – designed to attenuate linearly polarized laser beam continuously. Robust design and a wide choice of models for different laser lines and beam sizes.

• Designed for Yb:KGW/KYW and Nd:YAG laser wavelengths
• Laser damage threshold up to 10 J/cm²(10 ns @ 1030 / 1064 nm)
• Extinction ratio: >1:1000
• Clear apertures:  ⌀10 m -⌀22 mm
