Overview

PD Series laser beam dumps feature a patent-pending structure designed to absorb incident light and passively dissipate heat through natural convection. Laser beam dumps are used to capture unwanted and stray beams or contain a beam within a portion of an instrument.

Absorbs incident laser beams
Patent pending design minimizes backskatter
Up to 80 W maximum power
Multiple imperial and metric mounting options built-in

Notes:

General Notes:

To help identify the appropriate beam dump, utilize the Ophir Power Density Calculator to determine your specific power density or energy density requirements.
Caution: Beam dumps may become hot to the touch when operated near their maximum power rating.

Features

Enhanced Laser Safety with Backscatter Control

The PD Series Beam Dumps feature an innovative patent-pending structure designed to absorb incident light and passively dissipate heat through natural convection. The interior incorporates a Silicon Carbide scattering surface, effectively able to suppress and reduce backscatter of incident CW and Pulsed beams. As a result, laser safety for personnel and equipment is greatly enhanced.

Versatile Mounting Options

These beam dumps are designed to be post-mountable and feature an 8-32 and M4 threaded holes on opposing sides. This configuration allows for direct mounting onto a variety of our posts and pedestals. The PD30, PD50 and PD80 models are also equipped with front imperial and metric tapped holes, providing additional mounting options.

Easily Integrate with 30 mm Cage System

The PD10 and PD30 can be coupled with adapters (SP30C and AP30C respectively) to conveniently integrate into existing 30 mm cage assemblies.
