Externally Mounted Light Source

Externally Mounted

Externally mounted light source designed to ensure uniform radiance from integrating spheres

Features:

  • Compatible with Labsphere's Modular and Uniform Source Integrating Spheres
  • Long-life Rated for Greater Radiance Stability
  • Operates with Labsphere's Precision Lamp Power Supplies.

The External Halogen Light Source (EHLS) assemblies are designed to give you the ultimate flexibility with your integrating sphere. The EHLS projects light into the integrating sphere allowing you to place light attenuators and filter holders in the beam path. Add a variable attenuator to vary the light input or an optical filter to alter the spectral distribution.

Each EHLS consists of a tungsten halogen lamp with a dichroic or rhodium reflector mounted in a lamp housing. A simple twist of a screw securely mounts the lamp onto a 1 inch Labsphere port frame. The lamp is positioned outside the integrating sphere wall and stable radiance is projected into the integrating sphere. Each light source consists of a tungsten halogen lamp, lamp housing with integrated reflector and diffuser, and a 10 foot cable.
