PRODUCT FAMILY

Negative Spherical Lenses

Negative spherical lenses diverge incident light and extend the effective focal length of an optical system.

This family groups plano-concave and bi-concave geometries for beam expansion, collimator adjustment and negative-power imaging assemblies.

SELECTION QUESTIONS

Negative Spherical 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.
