Achromatic (Dual Wavelength) Beam Expanders

Special Optics Achromatic (Dual wavelength) beam expanders provide diffraction limited collimation at both 1064nm and 532nm simultaneously.  The air spaced designs enable usage in high power Nd:YAG applications.  The use of high efficiency antireflection coatings on all interior surfaces also ensures low reflection loss.
