Frequently Asked Questions

What is the primary purpose of this plano-concave lens?
This lens is designed to increase the divergence of a laser beam or serve as the negative optical element in beam expanders, telescopes, and other precision laser systems.
Why is UV fused silica used as the substrate?
UV fused silica offers excellent transmission across a broad spectral range, extremely low thermal expansion, high optical purity, and superior resistance to laser-induced thermal effects, making it ideal for demanding laser applications.
What advantages does the AR909 coating provide?
The AR909 coating is optimized for 1064 nm and reduces surface reflections to below 0.1%, improving optical throughput, minimizing ghost reflections, and reducing unwanted heating in high-power laser systems.
Is this lens suitable for high-power laser applications?
Yes. The combination of UV fused silica and ion beam sputtered anti-reflection coatings provides excellent durability, low absorption, and high resistance to laser damage, making the lens well suited for high-power laser environments.
What optical systems commonly use a -75 mm plano-concave lens?
A -75 mm plano-concave lens is commonly used in laser beam expanders, beam shaping assemblies, optical relay systems, scientific instruments, and precision photonics setups where controlled beam divergence or negative focal power is required.
