Product Desciption
Meniscus lenses are designed to minimize spherical aberration. When used in combination with another lens, meniscus lenses will shorten the focal length and increase the NA of the system without introducing significant spherical aberration. When used to focus a collimated beam, the convex side of the lens should face the source to minimize spherical aberration. Meniscus lenses include positive meniscus lens and negative meniscus lens. We offer meniscus lenses both coated and uncoated, a wide range of optical glasses for the meniscus lenses for your option, such as N-BK7, Fused silica, N-SK11, N-BAF10, sapphire, silicon glass, etc.

FQA:
Q1: How will you control the quality of the optics ?
We have strict quality control system in house. Our QA ladies are well trained, they will not let any unqualified optics shipping out. Each optics are tested carefully before delivery.
Q2: What's your payment terms ?
We prefer T/T in advance for the first order, but for the regular orders, we accept 30 days net account.
Q3: What are your advantaged products ?
We started with spherical lenses, our production guys have rich experience for production of spherical lenses, like plano convex lens, plano concave lens, double convex lens, double concave lens and achromatic lenses. But through years of development, we are also good at production of optical plates and windows, ball lenses, cylindrical lenses, cylinder lenses, cylinder rod lenses.
Q4: Can you offer the lenses in good quality ?
Yes, we can. Each lenses will be tested before delivery.
Q5: How many workers do you have for production and test ?
We have 65 workers, 58 of whom are professional skilled workers. Most of them joined Nanjing Shuncheng optical since the factory was founded. We have 6 skilled QA ladies to test surface quality, flatness, focal length and so on. New comers will get training before go to the position.
Q6: How will you send the goods ?
We worked with DHL for many years.
