114-0220E 25.4 mm Dia. x -150 mm FL; Uncoated; Double-Concave Lens
The 114-0220E is a high-quality double-concave lens, sourced from the reputable optical components manufacturer, EKSMA Optics. This lens is characterized by its concave-concave base shape and circular geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 25.4 mm and a thickness that varies from 4 mm at the edge to 3 mm at the center. It boasts an effective focal length (EFL) of -150 mm, indicating its diverging nature, which is further emphasized by its radii of curvature, r1 and r2, which are -156.1 mm and 156.1 mm respectively. The lens's inner and outer radii are both 0, suggesting a symmetrical design.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is designed to operate at a wavelength of 546 nm. The lens does not come with any coating, offering users the flexibility to apply the coating that best suits their specific application requirements.
