UM10-45A In Stock

The UM10-45A by ThorLabs is an exceptional low group delay dispersion (GDD) mirror that is designed to meet the demanding requirements of high-performance femtosecond laser systems and imaging applications. The UM10-45A offers a remarkable combination of reflectance greater than 99% and |GDD| less than 30 fs2, making it an ideal choice for applications where pulse broadening is a critical concern. The UM10-45A mirror is optimized to work seamlessly with Ti:sapphire femtosecond lasers, ensuring that optimal results can be achieved with minimal distortion. Additionally, this mirror is a perfect choice for imaging applications like two-photon microscopy, where high-quality mirrors with low GDD are essential for delivering outstanding results.

This UM10-45A is designed with a 45° angle of incidence and is compatible with wavelengths ranging from 700 nm - 930 nm. The mirror is coated with a dielectric thin film using the ion-beam-sputtering (IBS) technique, ensuring high precision and durability. The UM10-45A has a diameter of Ø1" and comes with an engraving on the edge of the optic that displays the item number and an arrowhead pointing to the coated surface. The back surface of the mirror is polished, making it possible to use the small percentage of light that leaks through the reflective coating for applications like power monitoring. The UM10-45A is a reliable and high-performance mirror that can handle the most demanding applications. With its outstanding combination of reflectance and low GDD, the user can expect exceptional performance and consistent results with every use.
