Meniscus Lenses

Meniscus lenses use one convex and one concave surface to control aberration while adding positive or negative optical power.

They are useful in compact imaging groups, beam-expander assemblies and systems that need improved off-axis performance.

SELECTION PRIORITIES

Choose meniscus lenses around the optical requirement

4 product families are available. Use the engineering filters below to narrow the catalog before comparing exact models.

Optical function

Choose positive or negative power and the geometry that matches focusing, collimation, expansion or one-axis beam shaping.

Focal length and aperture

Match effective focal length and clear diameter to the source, working distance, numerical aperture and available mount.

Material and coating

Select the substrate and antireflection band from the operating wavelength, thermal load and laser-power requirement.

SELECTION QUESTIONS

Meniscus Lenses FAQ

Technical answers to the questions that most often affect model selection.

How do I choose between a positive and negative optical lens?

Use a positive lens when the system must converge light, form a real image or collimate a diverging source. Use a negative lens for beam expansion, focal-length extension or divergence control. Meniscus, cylindrical and achromatic geometries address additional aberration, one-axis and broadband requirements.

Which lens material should I select?

K9 optical glass is a practical visible-range choice. UV fused silica is preferred for ultraviolet transmission, low thermal expansion and demanding laser use. Infrared materials such as silicon or calcium fluoride must be selected around their usable transmission band and environmental limits.

Which specifications should be checked before ordering a lens?

Confirm diameter, effective focal length, back focal length, center and edge thickness, surface quality, centration and coating band. The antireflection coating must match the operating wavelength and intended angle of incidence.
