Sometimes, a fiber collimator is used together with another optical component to perform a special function. The combination of a fiber collimator and quarter-wave plate will produce a half-wave plate reflector, and a combination of a fiber collimator with a Faraday rotator will produce a fibered Faraday mirror.

Grasp the handles so that your palms are facing down (or at a downward angle), maintain a small bend in your elbows, and move your hands down toward the ground following the angle of the cables.

NewportFiber Collimator

A fiber collimator may be adjustable, with screws for controlling beam directional and working distance, or fixed. It may be polarization maintaining. The exact fiber collimator you need will depend on the specifications of your application and the wavelength of light you need to have collimated as well as on collimated beam size.

When the weights are at the lowest point in the arc, contract your chest muscles and move the weights up along the same arc until your arms are back in the starting position. That’s one dumbbell fly.

The cable chest fly — also called a standing cable fly — is a variation of the weighted dumbbell fly that’s been a staple chest exercise for decades.

To perform the incline cable chest fly, position an incline bench between the cable uprights and set the pulleys to their lowest possible point. Then perform the movement as you would a weighted dumbbell fly.

To perform the decline cable chest fly, position a decline bench between the cable uprights and set the pulleys to their lowest possible point. Then perform the movement as you would a weighted dumbbell fly.

The output from an optical fiber can be collimated with a simple collimation lens placed at a fixed distance from the end of the fiber; a distance equal to the focal length. For ease of use, fiber collimators that are mounted to the fiber are often preferred.  These come in two types:

Because flys engage your muscles when they’re in a stretched position (with your hands out wide), they work your chest slightly differently than bench pressing movements.

Once in that position, you’ll move the weights away from each other in a downward arc while keeping your elbows slightly bent at all times.

At Avantier we can produce custom high-performance fiber collimators for every application. Whether you need a non-adjustable, permanently attached collimator for pigtailed fibers or a thermal-resistant adjustable collimator for use with a high powered laser, we can get you what you need. Our experienced optical designers are available to work with you and come up with a solution that provides the collimation you need while surmounting any challenges you might have. Call us today to schedule a first introductory consult or place your custom order.

The cable chest fly helps prevent imbalances because, when done correctly, it’s impossible for your left arm to compensate for your right arm (and vice versa). Both sides have to do their own work.

That’s one cable chest fly. Follow the same process — starting with contracting your chest muscles — to perform as many reps as your workout calls for.

The cable chest fly is an isolation exercise, which means only one joint is moving at a time. In this case, the shoulder joint takes the bulk of the load when you move your hands through the correct range of motion.

Compound exercises are great for building strength, size, and definition. But consider taking it up a notch by adding an isolation exercise into your routine, like the cable chest fly.

A muscle imbalance can develop when one side of your chest is stronger than the other. These imbalances can lead to back pain and discomfort when performing certain exercises.

The cable chest fly incorporates the same group of movements, but with cable-based weight stacks instead of dumbbells. Rather than moving dumbbells toward and away from each other, you’re moving handles attached to cables.

In a standard weighted dumbbell fly, you lie down on a flat bench, hold a dumbbell in each hand with handles parallel to your body — arms extended up in line with your shoulders, and elbows bent slightly (like you’re trying to hug a barrel or large tree).

Fiber collimators with mechanical interfaces that attach to a fiber connector. These can be designed to connect with whichever fiber connector you use; FC/PC, FC/APC and SMA are two popular options. These types of collimators are more expensive, but also more flexible as they can be easily attached or removed from a setup. Fiber collimators may include different types of lenses, including gradient-index (GRIN) lenses, singlet or doublet lenses. When you have a fiber with small mode radius and large beam divergent, you may need to use an aspheric lens to minimize aberrations.

Add to that the fact that you can use less weight during the exercise (while still experiencing strength gains), and it’s easy to see how the cable chest fly can be easier on your joints than some other exercises when performed correctly.

This stretched position engages more muscle fiber and requires the muscle to work a bit harder to move the weight from bottom to top. That targeted, stretched position helps your chest muscles get stronger faster (with the right routine, of course).

But what is a cable chest fly and how do you do it? Don’t worry — we’ve got you. In this article, we discuss the benefits of this exercise, the muscles it works, and how to perform it safely and correctly for the best results.

But to really target your chest without relying on other muscles to help get the job done, you’ll want to incorporate isolation movements, like the cable chest fly, that target specific muscles.

When compared to other chest exercises, the cable chest fly provides more tension on your muscles throughout the entire range of motion.

A fiber optic collimator designed for a large collimated beam will be longer and larger than one designed for a small beam. Collimators to be used in high power laser applications must also be optimized for the high power levels and heat present in such situations.

When you get into the correct position to start a cable chest fly, your muscles are already engaged under tension. That means it’s all but impossible for you to rest until you complete every rep and release the handles. And increased time under tension helps your muscles grow.
