This Bk7 cylindrical meniscus lens from Changchun Sunday Optoelectronics is engineered for precision optical applications, with diameters spanning 2 mm to 600 mm and a diameter tolerance of +0.00/-0.02 mm or custom design. Surface quality meets 10-5 scratch-dig, and surface irregularity is controlled to λ/10 at 632.8 nm or as specified. The lens features a thickness tolerance of +0/-0.02 mm, a clear aperture exceeding 90% of the diameter, and a chamfer of 0.05-0.5 mm x 45° tailored to customer requirements.
The Bk7 substrate provides high homogeneity and low inclusion content, typical for borosilicate optical glass used in imaging and laser systems. Centeration is held to 3 arcmin, and coating options include single-layer MgF2 or multi-layer AR coatings across bands A (350-650 nm), B (650-1050 nm), C (1050-1585 nm), or custom ranges. Bk7 is a standard choice for visible to near-IR applications where cost-effective performance and broad transmittance are required.
These lenses are used in beam shaping, line generation, and anamorphic systems for industrial, medical, and scientific instruments. Buyers typically source in bulk for OEM integration, with packaging and lead times aligned to project schedules. Importers should confirm coating compatibility with their wavelength range and verify chamfer specifications for mechanical assembly.

Before ordering, verify the lens’s coating compatibility with your system’s operational wavelength range, as mismatched coatings can reduce transmission efficiency. Confirm the diameter and thickness tolerances meet your mechanical and optical design requirements, particularly if the lens will be integrated into a multi-element assembly with tight spacing constraints.
Discuss logistics such as packaging standards for optical components, which typically include individual foam-lined cases to prevent scratching or contamination. Clarify lead times, as custom coatings or diameters may extend production schedules. Incoterms should be agreed upon upfront, with FOB or CIF terms common for optical imports from China, and payment terms often structured as 30% deposit with 70% balance before shipment.
Request quality inspection reports for surface quality, centration, and coating performance to ensure compliance with specifications. For critical applications, arrange third-party optical testing, such as interferometry for wavefront error or spectroradiometry for transmission curves. Ensure the supplier provides material certifications confirming BK7 composition and homogeneity, as deviations can affect thermal stability and optical performance.
