Attention! You can customise this product to your needs.
Tunable beam expander is Galilean type telescope, which allows compact design which is reasonable for industrial environment. Employed lenses are air spaced, thus expanders are suitable for high power applications. Altechna offers three different type beam expanders, 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.

varna Expansion ratios 1.5x-5x; 5x-8x; 2x-8x
varna High laser induced damage threshold
varna Transmission better than 97% even for two wavelengths
varna Fixed-length design option
