Professional Overview: The Science of Negative Focal Length In the realm of precision optics, the 60/40 40/20 Plano Concave Lens serves as a fundamental component for beam expansion and light divergence. A Plano Concave Lens is characterized by one flat surface and one inwardly curved (concave) surface, resulting in a negative focal length. This unique geometry allows the 60/40 40/20 Plano Concave Lens to diverge collimated incident light, making it indispensable for expanding laser beams or increasing focal lengths in existing optical assemblies. Our manufacturing process for the 60/40 40/20 Plano Concave Lens prioritizes surface integrity. By offering both 60/40 (standard commercial grade) and 40/20 (precision laser grade) scratch-dig surface qualities, we ensure that every Plano Concave Lens meets the specific scatter-loss requirements of your application. Whether you are integrating a 60/40 Plano Concave Lens into a basic lighting system or utilizing a 40/20 Plano Concave Lens for high-power laser manipulation, our lenses deliver consistent optical performance across the entire clear aperture.

Frequently Asked Questions Q: When should I choose a 40/20 Plano Concave Lens over a 60/40
Plano Concave Lens? Answer: The choice depends on your light source. A 40/20 Plano Concave Lens is essential for laser applications where surface defects can
cause localized heating or light scattering. If your application
involves non-coherent light, such as LED lighting, a 60/40 Plano Concave Lens offers the same mechanical precision at a more economical price
point. Q: How does the ±0.005mm diameter tolerance benefit my assembly? Answer: In high-precision optical barrels, mechanical play can lead to
decentration. By specifying a 60/40 40/20 Plano Concave Lens with a ±0.005 mm tolerance, you ensure a perfect concentric fit, which is vital for
maintaining the optical axis in sensitive imaging assemblies. Q: Can a Plano Concave Lens be used for high-power CO₂ lasers? Answer: Yes, provided the Plano Concave Lens is manufactured from Zinc Selenide (ZnSe). We apply our 40/20 surface standards to ZnSe substrates to ensure the lens can
withstand high-energy density without thermal fracturing. Q: How do you verify the surface irregularity of a 60/40 40/20
Plano Concave Lens? Answer: We utilize Zygo interferometers to measure the wavefront error.
Every 40/20 Plano Concave Lens undergoes a rigorous ΔN check to ensure the irregularity is within
0.1 to 0.5 λ, ensuring that the diverted light remains uniform and
predictable. Q: What is the lead time for a custom focal length 60/40 40/20
Plano Concave Lens? Answer: Our flexible production line allows for rapid prototyping. A
custom Plano Concave Lens with specific radii can typically be engineered and coated within
2-4 weeks, depending on the material and coating complexity. Q: What are your main products or which field do your products be
used? Answer: We are specialized in optical design, optical element processing,
and lenses assembly. Our products include Spherical lens,
Aspherical lens, Cylindrical lens, Reflector mirror, Filter, Rod
lens, Camera lenses etc. Our products are widely used in imaging,
laser, and lighting applications. Q: What's your advantage? Answer:
Q: What's your MOQ? Answer: 10 pieces. Q: What's your lead time? Answer: 1 day for inventory items and 25-35 days for new projects. Q: What's your shipping type? Answer: Usually by FedEx, DHL, TNT, EMS etc or customer appointed
carriers. Q: What's the payment condition? Answer: T/T, L/C, VISA, PayPal, Alipay or negotiation. Q: What's your quality guarantee period? Answer: Three years. |
