Optical Delay Lines: Key to Time-Resolved Measurements
To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.

Mounting Precision Enhances Laser Performance
Optical mounts frequently play a critical role in overall laser system performance, but their impact may become obvious only when optical misalignment from vibration, thermal drift or long-term mechanical creep causes system operation to degrade. This article reviews basic styles of optical mount design and construction, and compares various mount types in terms of stability, functionality and cost.

Active Alignment Techniques Improve Lens Centering
An optomechanical engineer faces many challenges when assigning tolerances for precision lens assemblies. Beginning with a functional requirement for optical centration, the engineer must determine mechanical tolerances for the various lens and housing components. To avoid overspecifying such tolerances, it is helpful to understand alignment and assembly processes that can achieve different levels of accuracy in the resulting optical centration.
