Product catalog summary

Technical Reference and Fundamental Applications

This document provides a comprehensive guide on lens selection, including spherical, cylindrical, and specialty lenses, as well as optics sets, optical systems, mirrors, and prisms.

Ordering Information

The document lists models with their respective wavelength ranges and dimensions. For example, the GBS-AR14 model covers a wavelength range of 430 nm to 700 nm and has specific dimensions provided in inches and millimeters.

Refractive Beam Shaper Accessory Products

To improve input beam quality, the use of a single-mode optical fiber is recommended, which can produce a nearly Gaussian optical profile. However, the optical power delivery is limited to several hundred milliwatts. Suggested products include precision single-mode fiber couplers and polarization-preserving single-mode fibers.

Improving Beam Quality with Spatial Filters

Spatial filters can be used to enhance beam quality. The document suggests specific models like the 910A Compact Five-Axis Spatial Filter and the 900 (M-900) Three-Axis Spatial Filter, with user-selected objective lenses and pinholes based on input beam parameters.

Input Beam Waist Size

For optimal performance, the input beam waist diameter should be 4.732 mm for the visible GBS-AR14. A zoom beam expander is recommended for adjusting the beam size. Suggested products include the ZB-128X Zoom Beam Expander and LP-2A Precision Lens Positioner.

Refractive Beam Shaper Mounting

The Refractive Beam Shaper requires precise mounting and alignment, with at least four degrees of freedom for optimal performance. Suggested products for mounting and alignment include the LP-2A Precision Lens Positioner and LP2A-1-32 Adapter.

When used with a high quality collimation optic, a fiber is capable of generating a good Gaussian optical profile. The drawback of a fiber input system is, of course, the optical power that can be delivered. Experience has shown that several hundred milliwatts can be delivered through such as system.

It is important that the parameters of the filter (input focal length, pinhole size) be chosen astutely for best power transfer and beam quality.
