Precision UV Fused Silica Aspheric Lenses
• Low f/#s for Optimum Light Gathering
• Low Coefficient of Thermal Expansion
• Prescription Information Available
TECHSPEC® Precision UV Fused Silica Aspheric
Lenses offer the benefits of an aspheric element
combined with the manufacturing precision of stateof
the-art grinding and polishing equipment. With the
available prescription data, these fused silica optics
can be easily designed and integrated into complex
optical systems. Featuring low f/#’s for optimum light
gathering and focusing performance, these fused
silica lenses are computer optimized to eliminate
spherical and minimize higher order aberrations. UV
fused silica optics substrate offers a low coefficient of
thermal expansion.

TECHSPEC® Near-Infrared (NIR) Precision Aspheric
Lenses are optimized to eliminate spherical aberration
in the near-infrared. Manufactured from SLAH64
or N-BK7 substrates and polished through a
computer numerical controlled (CNC) process, these
aspheric lenses achieve high precision performance
across the NIR spectrum. These NIR aspheric lenses
include uncoated substrates designed at 780 nm with
coating options at 350-700 nm, 600-1050 nm, or 900-
1700 nm. TECHSPEC® Near-Infrared (NIR) Precision
Aspheric Lenses are available with low numerical
aperture designs for applications that require beam
shape to be maintained as well as high numerical aperture
designs for light-gathering applications.
