λ/40 Aspheric Lenses
High-Precision Aspheric Lenses
• 0,25 μm RMS Aspheric Figure Error
• High Numerical Apertures to Maximize
Throughput
TECHSPEC® High Precision Aspheric Lenses are
CNC polished aspheric lenses that feature a 0,25 μm
RMS aspheric figure error. The precision aspheric
figure error makes these lenses ideal for applications
that require spherical aberration correction, including
imaging and laser focusing applications. These
aspheric lenses can also be used to replace multiple
spherical elements in optical assemblies to reduce
weight and cost.

• l/40 RMS Asphere Figure Error
• High Numerical Aperture Designs
• 3D Surface Profile Included with Each Lens
TECHSPEC® λ/40 Aspheric Lenses guarantee better
than λ/40 wave aspheric figure error. Achieved
via precision magneto-rheological finishing (MRF),
these aspheres offer high numerical apertures with
diameters ranging from 15 to 50 mm and are ideal for
a variety of imaging and low light level applications.
Each TECHSPEC® λ/40 Aspheric Lens is individually
measured and a 3D surface profile is included.
