1. What is a Plano-Concave Lens?
A plano-concave lens, also called a flat-concave lens, is an optical component with one flat surface and one inward-curved surface. It is designed to diverge light rays and expand laser beams in optical systems.

6. People Also Ask
- Q: What is the difference between plano-concave and biconcave lenses?
- A: Plano-concave lenses have one flat and one concave surface, while biconcave lenses have two concave surfaces, making them more powerful for diverging light.
- Q: Can plano-concave lenses be coated for UV applications?
- A: Yes, we offer UV anti-reflection coatings to optimize performance in ultraviolet light systems.
- Q: How do I choose the right plano-concave lens size?
- A: Lens size depends on your system’s beam diameter and required divergence angle; we provide custom sizing to fit your needs.
