Achromatic Lens

An achromatic lens is a crucial optical component designed to effectively minimize chromatic aberration, a common issue in lenses where different wavelengths of light are refracted at different angles. This lens is typically constructed using a combination of BK7, fused silica, and CaF2 materials, which work together to focus multiple wavelengths of light to the same point. This makes achromatic lenses an ideal choice for applications requiring improved image clarity and color accuracy.

Photonchina offers expertly engineered achromatic lenses that are tailored to meet specific needs. Our engineering team is capable of designing specialized focusing systems that enhance the performance of these lenses beyond standard configurations. By using a combination of two optical-grade glasses, these lenses significantly reduce spherical aberrations, making them an excellent replacement for single-component lenses where enhanced performance is desired.

For applications demanding precision and compactness, Photonchina provides super small achromatic lenses. These lenses deliver superior wavefront quality, reduced spot size, and an improved modulation transfer function (MTF). With diameters as small as 3mm and short focal lengths, these lenses are crafted under strict quality controls to ensure exceptional performance. The addition of anti-reflective coatings further enhances their efficiency, making them a valuable component in high-precision optical systems.
