Product Family Description

  • Stemmed Design Reduces Stress on Mirror Surface when Mounted by Stem
  • Durable Fused Silica Construction for Low Coefficient of Thermal Expansion
  • Enhanced Aluminum, Protected Gold, and Protected Silver Coatings
  • TECHSPEC® Laser and Broadband Dielectric Stemmed Mirrors Also Available

TECHSPEC® Metallic Coated Stemmed Mirrors provide low mounting stress on enhanced and protected metallic coated mirrors. Designed to be mounted to TECHSPEC® Kinematic Circular Optical Mounts and E-Series Kinematic Optical Mirror Mounts, all contact between the mirror and the kinematic mount is through the stem, reducing the stress imparted on the optical surface of the mirror. Due to their stress-reducing design and monolithic fused silica construction, these mirrors provide excellent thermal stability and improved surfaced flatness and durability compared to traditionally mounted λ/10 first surface mirrors. TECHSPEC® Metallic Coated Stemmed Mirrors can be easily mounted and integrated into optical systems and are ideal for beam-steering and reflection applications in the visible and IR spectra.

A comparison of the aberrations introduced to a λ/10 Stemmed Mirror and a λ/10 First Surface Mirror when mounted in a kinematic mount. As shown, a Stemmed Mirror stays within λ/10 specification up to 12 inoz of torque (“hand-tight”) while a First Surface Mirror becomes out of specification with a surface flatness of λ/5.

Stemmed Mirrors are mounted to kinematic mounts by a stem on their back surface, resulting in no contact with the edges of the mirror surface.
