  • Description: . This replacement reduces the number of back reflections and ultimately yields higher transmission. They are usually mounted in pairs, so that their convex surfaces are nearly in contact. These systems require lenses somewhat larger in diameter than the diagonal measurement of the slide or target

    • Lens Type: Aspheric Lens
    • Focal Length: 0.5118 inch
    • Materials: Other
    • Surface Quality: 80-50 Scratch / Dig
