Detailed Product Description
Round Convex Meniscus Lens
Product Overview

Our Round Convex Meniscus Lenses are engineered for high-performance optical assemblies, designed to significantly reduce spherical aberration in multi-element systems. By leveraging a steeper curvature on one side, these lenses provide superior wavefront control, making them indispensable for precision imaging and laser focusing tasks.

Engineering Excellence

Our engineering team selects premium substrates like Fused Silica or N-BK7, ensuring exceptional thermal stability and transmission rates. Whether you are developing a custom telescope or a medical diagnostic device, our lenses offer the technical reliability required for mission-critical applications.

Quality Assurance

Manufactured in our ISO-certified facility, each Round Convex Meniscus Lens undergoes rigorous interferometric testing to meet strict MIL-PRF-13830B standards, a trusted choice for Tier-1 optical integrators.

Every shipment includes a comprehensive QC report covering dimensional tolerances and surface flatness. We utilize Class 100 cleanroom packaging to ensure your optics arrive contamination-free and ready for immediate system integration.

Frequently Asked Questions
Q1: Why choose a Convex Meniscus lens over a standard Plano-Convex lens?
The primary advantage lies in aberration control. When used in combination with other lenses, a convex meniscus lens can significantly reduce spherical aberration and improve image sharpness. It allows for a more favorable distribution of refractive power, which is particularly critical in high-resolution imaging systems and laser beam steering.
Q2: What are the typical surface quality standards for your optical grade meniscus lenses?
Our standard production follows the MIL-PRF-13830B protocol, typically offering a 40-20 or 20-10 Scratch-Dig surface quality. For high-power laser applications, we provide precision polishing that ensures a surface roughness of Ra < 0.5 nm, minimizing light scatter and maximizing damage thresholds.
Q3: How do I determine the correct orientation (which side should face the source)?
For most applications aiming to minimize aberration, the surface with the steeper curvature (the convex side) should face the more distant object or the collimated light source. This configuration ensures that light rays are bent more gradually across both surfaces, leading to a smaller focal spot size.
Q4: Can these lenses be customized with specific Anti-Reflection (AR) coatings?
Yes. We offer a variety of thin-film coatings tailored to your application's wavelength. Options include:
  • VIS (400-700nm): Ravg < 0.5%
  • NIR (700-1100nm): Optimized for Nd:YAG or Diode lasers
  • Broadband AR (BBAR): For multi-spectral imaging
Each coated batch is verified with a spectrophotometer test report to guarantee performance.
Q5: What substrates are available for infrared (IR) applications?
Beyond standard N-BK7 and Fused Silica, we manufacture meniscus lenses using IR-optimized materials such as Germanium (Ge), Silicon (Si), and Zinc Selenide (ZnSe). These are ideal for thermal imaging and CO₂ laser systems where high transmission in the long-wave infrared spectrum is required.
Q: What are your main products or which field do your products be used?
We are specialized in optical design, optical element processing, lenses assembly. Such as Spherical lens, Aspherical lens, Cylindrical lens, Reflector mirror, Filter, Rod lens, Camera lenses etc. Our products are widely used in imaging, laser, lighting applications.
