Ocean Optics Provides Easy-to-Use Collimation Testers for Laser Light

Dunedin, Fla., May 2005 – Ocean Optics offers a comprehensive line of Shear-Plate Collimation
Testers that can be used to examine and adjust the collimation of laser light. Each tester is
available in apertures ranging from 10 mm to 200 mm in diameter and is usable from 350-2500
nm. Additionally, the testers are valuable tools for measuring the wavefront curvature and
divergence/convergence magnitude of optical components such as large-radius optics.
Each Ocean Optics Collimation tester is a lateral-shearing interferometer consisting of a wedged,
high-quality optical flat housed in a heavy-duty anodized aluminum frame. With no moving or
adjustable parts, the collimation testers are remarkably easy-to-use and produce instant results.
To examine an optical wavefront in a collimating system, the user simply places an Ocean Optics
Collimation Tester at a 45-degree angle incident to an expanded beam so that the face of the
collimation tester is illuminated. The beam is reflected onto a screen placed at a right angle to the
reflected beam. Two overlapping circular images bisected by the shadow of the collimation
tester's reference wire will appear on the screen. Fringes -- parallel patterns of light and dark
areas – can be seen in the overlap region of the two images. To properly collimate the beam, the
user simply adjusts the collimating system until the fringe pattern is parallel to the shadow of the
tester's reference wire.
