Plano‑Convex Spherical Lenses from Changchun JH Optics
Published: 2026-08-20 10:42:50 Views: 20
As fundamental refractive optical components, plano‑convex spherical lenses consist of one convex spherical surface and one flat surface. Widely used for beam focusing, collimation and image formation, they are essential building‑blocks for laser systems, spectroscopic instruments, machine‑vision equipment and laboratory optical setups. Changchun JH Optics Co., Ltd. supplies fully custom‑fabricated plano‑convex spherical lenses. With well‑established optical grinding, high‑precision polishing and metrology capabilities, the company delivers spherical lenses with superior surface figure and surface quality for global customers.
Premium Certified Optical Substrates
Blank materials are sourced from world‑renowned RoHS‑compliant optical glass manufacturers, including CDGM, SCHOTT, OHARA, HOYA and CORNING. High batch‑to‑batch consistency and excellent optical homogeneity guarantee stable optical performance and long‑term reliability of finished lenses.
Custom Manufacturing Specifications
- Diameter: Available sizes range from 0.5 mm to 500 mm, covering micro‑optics and large‑aperture industrial lenses.
- Radius of Curvature: Curvature radius can be customized from 0.5 mm to infinity. Infinite‑radius surfaces correspond to flat planes for flexible focal‑length design.
- Centration Error: High‑precision centration measuring instrument reaches the measurement accuracy of 3 arc‑seconds for components up to 3 inches, minimizing offset between optical axis and mechanical center.
- Surface Quality (S/D): The highest achievable scratch‑dig specification is better than 10/5. Standard industrial grades such as 60‑40 and 40‑20 are also available based on application requirements.
- Surface Flatness: The reference interferometer lens achieves surface figure accuracy better than λ/20. Mass‑produced plano‑convex lenses can reach measurable surface performance superior to λ/20.
- Transmitted Wavefront RMS: Measured wavefront‑error test reports can be provided upon request. Final wavefront performance depends on substrate material and lens geometry, and will be technically evaluated before production.
Additional tolerance parameters including edge‑sag and concentricity can be assessed case‑by‑case. Please send your drawings and specifications for custom plano‑convex spherical lens quotation and technical review.
