Achromatic Triplet Lenses

One-stop customized production: Solar Valley processes a variety of round and square achromatic triad lenses, such as positive achromatic lens, negative achromatic lens, asspherical achromatic lens and so on achromatic lenses,  according to customer requirements.

Material: Use a variety of high and low refractive index optical glass, calcium fluoride lenses,  optical quartz, fused quartz substrates, and other materials.

Achromatic triplet lens performance: Tianyang Valley strictly matches the diameter and center thickness to ensure the adhesive thickness and the center thickness required by high precision. Using UV curing/gluing technology on different glass materials, Tianyang Valley dynamically adjusts the optical center of the three parts during the gluing process, eliminating the overall optical center eccentricity after gluing. For high refractive index optical materials, the use of high refractive index UV photosensitive adhesive corresponding, accurate control of the center thickness tolerance of the adhesive can be used for optical design that is very sensitive to air spacing. From ultraviolet to near-infrared achromatic lenses, the operating band can be 193nm to 1000nm, achieving a consistent focal length and minimizing spherical aberration performance.
