Engineers are available to assist.
Edmund Optics® uses a wide variety of state-of-the-art metrology technologies to ensure that all specifications are met. Our in-process metrology capabilities include cavity ring-down spectroscopy, white light interferometry, non-contact 3D profilometry, and much more. An in-house laser testing lab allows for internal process improvement and verification of laser damage threshold.
 Special LED source used to measure parallel, flat surfaces while minimizing reflections off back surfaces
 Eliminates the need for special treatment of the rear surface, which minimizes measurement time, the risk of damage to the part, and the risk of inaccurate measurements
 Ideal for measuring dual-side-coated optics such as IBS coated mirrors with stress-compensating coatings on the backside
 Accurately measure absorption for better characterization of the spectral properties of optical coatings and substrates
 A pump-probe geometry measures change in refractive index due to absorption-induced thermal expansion
 More sensitive and accurate absorption measurement for very low levels of absorption than spectrophotometers, which determine absorption indirectly by directly measuring transmission
 In-house testing to measure assembly performance
 Transmitted wavefront error
 Laser beam profiling
 Measuring power in bucket and energy on target
 Development of application-specific tests
 In-house laser lab performing long-run applied UV laser exposure experiments at 355nm with a 10ns pulse duration
 Laser-induced contamination is a key concern for UV laser systems
 Contamination resulting from the environment or outgassing can significantly reduce performance or lead to system failure
 Intimate knowledge of cleaning and assembly techniques to mitigate these effects
