Product catalog summary
Technical Reference and Applications Overview
This document serves as a comprehensive guide for lens selection, focusing on various types of lenses including spherical, cylindrical, and specialty lenses. It also covers optics sets, optical systems, mirrors, and prisms.

Antireflection Coatings
The document provides detailed specifications for broadband antireflection (AR) coatings across different wavelength ranges:
  • AR.10: Broadband UV AR Coating (250-450 nm)
  • AR.14: Broadband VIS AR Coating (400-700 nm)
  • AR.16: Broadband NIR AR Coating (600-1100 nm)
  • AR.18: Broadband IR AR Coating (800-1300 nm)
Each coating is characterized by its reflectance percentage at typical angles.

Lens Specifications
The guide includes a detailed table of BK 7 Precision Bi-Convex Lenses, specifying:
  • Model number
  • Diameter (mm)
  • Effective Focal Length (EFL) (mm)
  • f/#
  • Back Focal Length (BFL) and Front Focal Length (FFL) (mm)
  • Physical parameters (P1, P2, Tc, R)
These lenses are made from BK 7 optical glass with surface irregularity ≤λ/4 and a scratch-dig specification of 40-20. They are available with broadband or laser line AR coatings.

Ordering Information
To order a lens with a specific AR coating, the coating code (e.g., AR.14, AR.16, AR.18, AR.33) should be appended to the lens product number. For example, KBX064+AR.14 becomes KBX064AR.14.

Additional Resources
The document references additional tools and accessories such as the AC Series Adjustable-Radius Chucks and the LA1V-XY Lens Positioner, which are detailed on other pages.
