Tunable beam expander is Galilean type telescope, which allows compact design which is reasonable for industrial environment. Emplyed lenses are air spaced, thus expanders are suitable for high power applications. Altechna offers three different type attenuators, each type is designed for specific application: 
  • For Nd:YAG lasers 
  • For Femtosecond lasers 
  • For two wavelengths (e.g. High power beam + guiding beam, or fundamental + harmonic).
Standard beam expanders are designed for four most popular lasers: Nd:YAG; Ti:Sapphire; Yb:KGW and Yb:YAG, but custom wavelengths are available. Standard mouinting thread is M27x1, which is compatible with common 4-axis mounts. Models with 1.5x-5x and 1x-8x magnification distinguish by their “fixed-length” design which simplifies both integration and usage.
varna "One turn adjusment" option
varna Expansion ratios 1.5x-5x; 5x-8x; 2x-8x
varna High laser induced damage threshold
varna Transmission better than 97% for both wavelengths
varna Fixed-length design option
