Large-aperture aspherical lenses are designed for collimating, focusing, and imaging.
The paraxial aberrations are completely corrected for monochromatic light.
Very high image quality can be achieved for a narrow bandwidth.
- Single element
- Diffraction limited
- 630 nm to 1550 nm
- Use as alignment flats or
for collimating
|
- Ease of assembly
- Piece to piece uniformity
- Negligible birefringence
- Broad environmental
stability range
|
- Applications:
Fiber communications
Optical data storage
Instrumentation
Bar-code scanners
Printers
Medical

You have the choice of ordering a lens by itself, a holder by itself, or a
lens-and-holder combination. Lenses and lens assemblies (lens + holder) are
available in relative apertures of 1/3.5, 1/4, and 1/5. When ordering a lens,
please specify the relative aperture and the wavelength you need it for.
