• Stemmed Design Reduces Stress on the Mirror Surface when Mounted by Stem
• Monolithic Fused Silica Construction
• Designed to Fit TECHSPEC® Circular Kinematic Mounts and E-Series Kinematic
Optical Mirror Mounts
TECHSPEC® Stemmed Mirrors are flat mirrors designed to be mounted by a stem on their back surface 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. These mirrors feature a monolithic design and are manufactured from fused silica. TECHSPEC®
Stemmed Mirrors can achieve a higher surface flatness when mounted than λ/10 flat mirrors directly mounted
into kinematic mounts due to their stress-reducing design.

• Greater Than 99% Reflection Over Broad-
Wavelength Ranges
• Designed for all Polarization States from
0 - 45° AOI
• Excellent Thermal Stability
TECHSPEC® Broadband Dielectric λ/10 Mirrors are
ideal for beam steering or reflection applications utilizing
multiple laser sources. These dielectrically optical
mirrors feature greater than 99% reflection, significantly
better than that of metal coated mirrors, and
increases system performance by minimizing energy
loss. The highly durable fused silica substrate offers a
low coefficient of thermal expansion and a high resistance
to abrasion. TECHSPEC® Broadband Dielectric
λ/10 Mirrors are designed for applications from the
UV to the near-infrared spectra.

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