Mounting flat mirrors by their edges in a kinematic mount imparts stress onto the mirror surface. This results in distortion and reduced quality of the reflected wavefront, which is especially noticeable when using high-quality mirrors. Stemmed mirrors, on the other hand, are mounted from a smaller diameter “stem” protruding from the back of the mirror, resulting in significantly reduced stress on the mirror surface, high stability, and cost reduction and can be used as a replacement for a more expensive and complex kinematic mount and a conventional mirror.
UV grade fused silica is ideal for UV and visible applications, but IR grade fused silica has better transmission in the IR due to a lack of OH- impurities.
Highly-Dispersive Ultrafast Mirrors for Dispersion Compensation
Learn how Highly-Dispersive Mirrors compensate for dispersion and compress pulse duration in ultrafast laser systems, which is critical for maximizing performance.
Schwarz Mirrors minimize unwanted stray light using an opaque, engineered fused silica substrate that absorbs light that would otherwise be transmitted.
I recently removed the IR cut filter from my camera and did not replace it with any type of clear glass. It has since lost sensitivity in the IR, which was the goal, but also focus ability in the optics. Can you explain why this is so?
I would like to use your Off-Axis Mirror in a laser application with high temperatures. What is the maximum damage threshold and temperature limit these mirrors can withstand?
Edmund Optics' panel of laser optics experts discuss why the industry standard of measuring transmission to infer the reflectivity of high reflectivity laser mirrors doesn’t tell the whole story.
