Product Family Description

  • λ/40 RMS Asphere Figure Error

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 50mm 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. For diffraction-limited aspheres designed at specific Nd:YAG laser wavelengths, see our TECHSPEC λ/40 Laser Grade Aspheric Lenses.
