An In-Depth Look at Doublet Lenses

The intricacies of optical elements stem from the differences between simplified, idealized elements utilized for simulations and real optical components that carry certain limitations. Doublets serve as a solution to mitigate optical imperfections in your optical setup. Let’s delve deeper into their mechanics.

Understanding Doublet Lenses

A doublet lens comprises two lenses made from distinct materials that are bonded together.

Every optical substance exhibits chromatic dispersion, which is characterized by its Vd value. This dispersion results in the scattering of signals across various wavelengths.

The primary aim of constructing a doublet lens is to employ complementary dispersive materials that counteract chromatic dispersion, leading to a final doublet lens that maintains uniform focusing power across its entire wavelength spectrum.

These lenses are often referred to as achromatic lenses, indicating their capability of minimizing chromatic dispersion, and the term achromatic doublet is frequently used as well.

Fabrication Process for Achromatic Doublets

The construction of achromatic doublets typically involves two different types of glass: Flint glass and Crown glass. A concave lens is usually crafted from Flint glass, while a convex lens is made from Crown glass, ensuring they share a similar radius of curvature for easier cementing.

Flint glass possesses a high refractive index, resulting in significant scattering of light rays according to their wavelength. Conversely, Crown glass is known for its low dispersion properties. Identifying whether a glass is Flint or Crown is straightforward, as its title will incorporate an 'F' for Flint or a 'K' for Crown (for instance, the frequently used N-BK7 from Schott or H-K9L from CDGM).

The cementing of the two lenses to create the doublet is executed using a thin layer of optically neutral adhesive, which solidifies when exposed to UV light. Proper alignment of both lenses during this process is crucial for achieving a successful achromatic lens.

To further enhance optical transmission, anti-reflective coatings are often applied to the external surfaces post-cementing.

Benefits of Achromatic Doublets

Doublets contribute to improved optical performance by reducing both chromatic dispersion and spherical aberrations. Their initial development occurred in the 18th century in England, primarily for use in telescopic applications.

Today, numerous imaging applications within the visible spectrum utilize doublets, including:

• Astronomy
• Endoscopy
• Microscopy
• Photography

Purchasing Guidelines for Doublet Lenses

While designing a doublet lens is not overly complex, it requires expertise from an optician to thoroughly understand available materials and to define the surface contours of the two lenses.

The design deliverables will encompass a detailed drawing that specifies the optical glass selection for each component alongside an assembly illustration delineating coating requirements, which may include requests for blackening the doublet's edges.

Upon finalizing the design, high-precision optics manufacturers capable of assembling doublet lenses can respond with quotations for its production.
