Triplet Lens

The working principle of triple cemented achromatic lens

Its core technology lies in its unique optical design and gluing process. This lens consists of three different cemented optical elements, each with a different refractive index to accommodate different wavelengths of light. It enables the elimination and control of chromatic aberration by precisely adjusting the thickness and refractive index of each element, as well as the gluing angle between them.

The triplet achromat is the simplest lens combination for correcting all primary aberrations. The three-component design helps to maximize the correction or elimination of pincushion distortion, chromatic aberration and spherical aberration.

BOTE optics offers various styles of doublet achromatic lenses. At the same time, BOTE optics also provides a variety of anti-reflection coatings suitable for ultraviolet, visible or infrared light.

The triple objective lens can advantageously correct chromatic aberration because the radius of curvature of the mirror surface, lens material, lens thickness and mutual gap can be selected arbitrarily. When the relative aperture is very small, if the glass is properly selected, the secondary spectrum can be eliminated. We call this type of objective lens an apochromatic objective lens. Triplet lenses can also be designed as astrophotographic objectives.

As an important technological achievement in the field of optical instruments, triple cemented achromatic lenses have the advantages of high precision, high stability, and low cost, and provide strong support for the development of modern optical instruments. With the continuous advancement of optical technology and the continuous expansion of application fields, it will continue to play its important role and promote the further development of the optical instrument industry.
