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. Technical Specifications
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. Product Images 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:
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. Q: What's your advantage?
