λ/40 Laser Grade Aspheric Lenses
• 1/40 Wave Aspheric Surface Figure Error (RMS)
• Strehl Ratio >0,8
• Laser Line V-Coats with <0,25% Reflection
TECHSPEC® λ/40 Aspheric Lenses are polished through precision magnetorheological finishing (MRF), providing
them with an ultra-smooth aspheric surface with an aspheric surface figure error of λ/40 RMS. The
resultant aspheric lenses feature a Strehl Ratio above 0,8, guaranteeing diffraction-limited performance at the
specified design wavelength. TECHSPEC® λ/40 Aspheric Lenses are coated with a high-performance Laser
Line V-Coat to minimize reflection when used at their Nd:YAG design wavelengths. Standard imperial sizes
with f/2 designs made from fused silica are ideal for integration into OEM applications.

• Reduces Spherical Aberration
• Broadband AR Coatings Available
TECHSPEC® Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from
divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase
the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce
the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight
while providing advantages such as increasing throughput or simplifying assembly.
