Step Down Adapters for Oriel Light Sources

Product catalog summary

Calibration Sources: The document provides technical specifications for various calibration sources including deuterium, arc, incandescent sources, monochromator, fiber illuminators, solar simulators, and photolithography instruments.

Step Down Adapters: These adapters are designed to convert larger series flanges to smaller ones, specifically from 3 or 2 inch series to 1.5 inch series, and from 3 inch series to 2 inch series. This allows for compatibility with a wider selection of accessories. It is noted that there may be power loss from a collimated beam due to the reduction in clear aperture, but this can be mitigated if the beam is focused and then re-collimated using a secondary focusing lens assembly.

Ordering Information: The document lists models of step down adapters with their respective conversion specifications and clear aperture reductions. For example, Model 66292 converts a 2 Inch Series Male to a 1.5 Inch Series Female with a clear aperture reduction from 1.9 to 1.3 inches (48 - 33 mm).

Keep in mind that there will be power loss from a collimated beam due to the reduction in clear aperture. If the beam is focused, the step down can be made without power loss. You can then re-collimate the beam with a 1.5 Inch Series secondary focusing lens assembly.
