High-precision equiconcave lens
Introducing our high-precision equiconcave lens. This lens is expertly crafted from H-ZF1 glass, offering exceptional performance for a wide range of optical applications. Its equiconcave design, with identical concave surfaces, is ideal for diverging light and is a staple in systems requiring the expansion of light beams or the increase of focal lengths.
Key features
- Premium material: manufactured from high-quality H-ZF1 glass for excellent optical properties.
- Broadband anti-aeflection coating: Coated on both surfaces for minimal reflection and maximum transmission across the 400nm to 1000nm wavelength range.
- Precision canufacturing: engineered to tight tolerances for consistent and reliable performance.
- Protective chamfer: Features a protective chamfer to prevent chipping and ensure durability.
