Product catalog summary
Lens Selection Guide Overview
This document serves as a technical reference for selecting various types of lenses, including spherical, cylindrical, and specialty lenses. It also covers optics sets, optical systems, mirrors, and prisms.
BK 7 Precision Plano-Concave Lenses
The lenses are made from BK 7 optical glass and feature a surface irregularity of ≤λ/4 with a 40–20 scratch-dig specification. They are available with broadband or laser line antireflection (AR) coatings. Standard diameters and focal lengths are offered.
Ordering Information
To order a lens with an AR coating, append the coating code (e.g., AR.14, AR.16, AR.18, AR.33) to the lens product number. For example, KPC034 + AR.14 becomes KPC034AR.14. Detailed AR coating specifications are available on page 455.
Lens Specifications Table
The table provides detailed specifications for various lens models, including diameter, effective focal length (EFL), f-number (f/#), back focal length (BFL), front focal length (FFL), P2, thickness at edge (Te), and radius (R).
Availability
Guaranteed availability for select items is provided at newport.com.
