Laser Collimator Successful Because of Our Optical Gold Coating Expertise

Critical Nature of Exact Optical Coating Specifications

Understanding specifications and environmental requirements is absolutely critical when coating large scale optical components. So when a customer came to us unsure of the exact specifications for a gold coating of their large laser collimator, we were all ears.

Collimation

“Collimation” refers to all the optical elements in an instrument being on their designed optical axis. It also refers to the process of adjusting an optical instrument so that all its elements are on that designed axis (in line and parallel). With regards to a telescope, the term refers to the fact that the optical axis of each optical component should be centered and parallel, so that collimated light emerges from the eyepiece. Most amateur reflector telescopes need to be re-collimated every few years to maintain optimum performance. This can be done by simple visual methods such as looking down the optical assembly with no eyepiece to make sure the components are lined up. However, collimating a large telescope requires special, very precise equipment.

EMF’s Optical Gold Coating Expertise Ensures Success

Dynasil’s EMF technical team discussed with the customer at length the application and environmental requirements for the component. Their expertise helped the customer narrow down their options and ensured the end product was going to be exactly what they needed. Once the optimal characteristics for the customer’s product were finalized, EMF got to work.

Upon completion of the project, we delivered to the customer one of the largest gold coated optical components in our history.  Being able to assist the customer in developing the requirements, and then delivering a coating that even surpassed these requirements,  was only possible because of the combination of EMF’s willingness to listen and their optical coating expertise.
