Import Achromat Lens — Buy in Bulk from Supplier in China

Achromat lenses from Tian Cheng Optics Co., Ltd. are precision optical components designed to correct chromatic aberration, a common issue in imaging and laser applications. These lenses consist of two elements: a positive low-index crown glass cemented to a negative high-index flint glass, optimized for wavelengths of 480.0 nm, 546.1 nm, and 643.8 nm. The standard material used is BK7 grade A optical glass, a borosilicate glass known for its excellent optical clarity and low thermal expansion. The lenses are available in diameters ranging from 0.5 mm to 350 mm, with a diameter tolerance of +0.0/-0.15 mm and a thickness tolerance of ±0.2 mm.

In addition to chromatic aberration correction, these achromatic doublet lenses also reduce spherical aberration and coma, making them ideal for applications requiring high-resolution imaging. Surface quality is specified as 60-40 scratch and dig, a standard for precision optics, while surface irregularity is limited to λ/4 at 632.8 nm. The lenses can be supplied uncoated or with anti-reflective (AR) or high-reflective (HR) coatings, depending on the application. Centration tolerance is maintained at 85%, ensuring optical axes alignment for consistent performance.

Tian Cheng Optics Co., Ltd. offers both positive and negative achromatic lenses, with standard part numbers such as TPA101 to TPA105 for positive lenses and TNA101 to TNA102 for negative lenses. These lenses are used in microscopy, telescope systems, laser beam steering, and machine vision applications. The company’s production capacity supports custom sizes, materials, and coatings upon request, catering to specialized optical needs. Buyers typically source these lenses for integration into scientific instruments, industrial inspection systems, and defense optics.

Tian Cheng Optics Co., Ltd. is an optical components manufacturer based in Changchun, Jilin Province, China. The company operates from No.1188 Ruipeng Street, Chao Yang Zone, a location known for its concentration of precision engineering and optics firms. Their harbor trust tier indicates a baseline level of verification, though response metrics such as rate and hours are currently unavailable.

The supplier specializes in the production of achromatic lenses, offering both standard and custom solutions for visible and laser applications. Their product range includes positive and negative achromats, with detailed specifications provided for focal length, diameter, and material combinations. Tian Cheng Optics does not disclose additional details such as certifications, production volume, or client references in their profile, so buyers should request this information directly.
