Overview: An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as F2, which has relatively high dispersion, and the other is a positive (convex) element made of crown glass such as BK7, which has lower dispersion. The lens elements are mounted next to each other, often cemented together, and shaped so that the chromatic aberration of one is counterbalanced by that of the other.
Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy.
General Specifications Of Positive Achromatic Lens:
Standard Products Of Positive Achromatic Lens:
Coating Options Of Achromatic Lens: Star Optic offers a large variety of Achromatic Lenses. The above standard achromatic lens are coated with single layer MgF2 centered at 550nm. We have other multiple anti-reflection coating options for the Ultraviolet (UV), visible, or Infrared (IR) are available, including UV-VIS, VIS-NIR, NIR II, or SWIR. Additionally, Achromatic Lenses designed specifically for the Ultraviolet (UV) or Infrared (IR) are available, which offer superior performance when compared to a standard Achromatic Lens that has been coated for the same or comparable wavelength range.
Mounting Options For Achromatic Lens: An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses. Our standard achromatic lenses are unmounted. However, we can provide fixed mount and adjustable mount for our lenses.
Custom Your Own Lens: You have your full design freedom, and we are able to work with complex designs to get you exactly what you need including optical design, mechanical design and optical coating design.

UV FS Spherical Glass Lens MgF2 Coating Double Convex Lens With Fixed Mount
Double Convex (Bi-Convex) Spherical Lens, UV Fused Silica, Finite Imaging Lens Overview: Double-Convex (DCX) Lens, also referred to as bi-convex lens, has two positive, symmetrical faces with equal radii on both sides. These lenses are generally recommended for finite imaging applications. Bi-convex lenses are most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object distances (conjugate ratio) is between 0.2 and 5. Star -
CaF2 Cylindrical Concave Lens Curved Surface Cylinder Laser Lenses
Plano Concave Cylindrical Lens, Rectangular, UV Fused Silica Overview: Plano Concave Cylindrical lens is also called negative cylindrical lens act as plano-concave spherical lenses, except on only one axis. These lenses are used in applications that require one dimensional shaping of a light source. A typical application is to use a single cylindrical lens to turn a collimated laser into a line generator. Pairs of cylindrical lenses may be used to anamorphically shape images. -

Large Feild Angle Optical Waveplate 12.7mm True Zero Order Waveplate
True Zero Order Λ/2 Half Wave Plate, Large Feild Angle, For Imaging Systems Overview: Comparing with normal two plates design Zero order waveplates having a relatively larger thickness which reduces the field angle, the True zero order wave plates are made of a very thin plate or cemented with a BK7 substrate, which ensures the best possible field angle, temperature and wavelength performance. True zero order waveplate is widely used in laser Lab and optical instrument. True
