43-710 2.50 mm Dia. N-BK7 Ball Lenses Uncoated

The 43-710 2.50 mm Dia. N-BK7 Ball Lenses Uncoated are precision optical components designed for a wide range of applications. Sourced from the renowned vendor Edmund Optics, these lenses are known for their exceptional quality and performance.

The lenses feature a base shape of a circle, with a diameter of 2.50 mm, making them suitable for use in compact optical systems. The material used for these lenses is N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is identified by the vendor as "n-bk7 schott," indicating its high-quality Schott origin.

The N-BK7 material is particularly suitable for applications that require high transmission in the visible spectrum. The wavelength of 587.6 nm, specifically the d-line of sodium, is often used as a reference for this transmission.

These ball lenses come uncoated, offering users the flexibility to apply their own coatings based on their specific application requirements. However, it's important to note that uncoated lenses may have higher surface reflections, which could affect the overall system performance.
