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.

• CNC Polished Aspheric Surface
• S-LAH64 or N-BK7 Substrates
• Optimized for Applications in the NIR
TECHSPEC® Near-Infrared (NIR) Precision Aspheric
Lenses are designed at 780nm and are optimized to
eliminate spherical aberration. Manufactured from SLAH64
or N-BK7 substrates and polished through a
computer numerical controlled (CNC) process, these
aspheres achieve high precision performance across
the NIR spectrum. 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.
For custom designed CNC polished aspheric lenses,
please contact us.
