Holmarc offers wide collection of lenses for UV, Visible and NIR applications. Our collection of lenses includes, convex and concave lenses, cylindrical lenses, achromatic lenses, cylindrical achromatic lenses, axicons etc. All the lenses are available in uncoated or Anti-Reflection coated options. In addition to the standard items custom lenses as are also available.



Spherical Singlets


Plano - Convex Lenses

Plano - convex lenses are positive spherical lenses having convex surface on one side and flat surface on the other.



Bi - Convex Lenses

Bi-convex lenses are positive spherical lenses having convex surfaces on both sides. Holmarc manufactures bi-convex lenses with equal radii on both sides



Plano - Concave Lenses

Plano - concave lenses are negative spherical lenses with one concave surface and one flat surface. These lenses can be used to diverge light or to increase the focal length of an optical system.



Bi - Concave Lenses

These lenses have spherical concave surfaces on both sides. Holmarc manufactures many of these lenses as standard products.



Meniscus Lenses

Positive meniscus lens is a convex-concave lens thicker at the center than at the edges. It is used to minimize spherical aberration.



Cylindrical Lenses


Plano - Convex and Plano - Concave Cylindrical Lenses

Plano-concave lenses have a negative focal length and are used for image reduction or to spread light.



Cylindrical Achromatic Lenses

Holmarc’s cylindrical achromatic lenses are used to focus polychromatic light in one dimension with reduced spherical and chromatic aberrations.



Achromatic Lenses


Positive and Negative Achromatic Lenses

Achromatic lenses can be used as collimators, focusing lenses or light collectors. They are designed to eliminate chromatic and spherical aberrations



Cylindrical Achromatic Lenses

Holmarc’s cylindrical achromatic lenses are used to focus polychromatic light in one dimension with reduced spherical and chromatic aberrations.



Axicons


Axicons

Axicons are optical components which can be used to convert a collimated laser beam into a ring shaped non-diffractive Bessel beam.
