Features and Benefits

Reduced granularity in laser output intensity

Fiberguide’s De-Speckler System averages the modal noise in a single optical fiber to lower the speckle contrast, which increases the image contrast.

Most original equipment manufacturers (OEMs) require a speckle-reducing solution that can fit within their application, although most take up a significant amount of space. Fiberguide’s De-Speckler System is an ideal choice for any application requiring a small, integrated design.

Small form factor with a 76.00mm (3") length:
• Works well in space-constrained applications.

Overview

Life science OEMs, along with manufacturers of laser projectors and photolithography and other equipment that rely on multimode fiber optics, risk less-than-optimal performance due to mutual interference, or "speckle," in the transmission of lightwaves. The Fiberguide De-Speckler System averages the modal noise in a single optical fiber to reduce granularity in laser output intensity.

Most OEMs require a speckle-reducing product that can fit within their application, though most speckle-reducing products require an unrealistic amount of space. (See below.) Fiberguide’s De-Speckler System is about 76.00mm (3 inches) in size and can provide custom fiber lengths to fit any application.

A simple all-in-one design is ideal for most applications. The ability to reduce the amount of moving parts/equipment allows for a greater range of applications to achieve speckle reduction. The all-in-one De-Speckler System requires no additional equipment and works by plugging it in.

Frequently Asked Questions

What is speckle?
Speckle is a random granular pattern in an image. It’s caused by mutual interference of modes traveling down the fiber.

What are the different types of interference?
1. Dark spots are out of phase and cause destructive interference
2. Light spots are in phase and cause constructive interference

How does Fiberguide’s De-Speckler System work?
Fiberguide De-Speckler System technology uses mechanical agitation to average modes in a fiber. And it’s the mode averaging that reduces speckle.
