25 May 2010 . The Optical Surfaces Ltd. range of Laser Beam Expanders provide a proven means of focusing and shaping laser beams with a high degree of accuracy.
Designed to be easy to use and to provide accurate, unobstructed and achromatic expansion of any collimated input source - four standard beam expanders are available offering x5, x10, x15 & x20 magnification. OSL Beam Expanders are ideal for applications in which a small spot must be formed at some distance from the laser, or where the collimation range must be extended for illumination, or for alignment of distant objects.
Manufactured to better than lambda/10 surface accuracy, the off-axis design of OSL Laser Beam Expanders produces no central obscuration & highly efficient transmission is obtained, unspoilt by spider diffraction patterns. |
