Over the course of a few days, write down when you have to go and when your bladder loses control. Then look for connections. You may find patterns you can change easily, like that urge that always hits when you’ve drank your after-lunch coffee.

When you are wondering “how much pee can a bladder hold”, a summary below shows the average volume of a normal bladder by age.

Fiber collimators are often used to introduce light into an optical setup from a fiber coupled source. Thorlabs offers a variety of fiber collimator packages, some only provide a smooth barrel (like the triplet collimators) and others have a metric thread at the end of the barrel (like the asphere collimators).

Your bladder has receptors that tell your brain how full your bladder is. Essentially, there's an invisible “fill line” in your bladder.

These adapters are designed to mount Thorlabs' C-Lens Fiber Collimators in SM05- or SM1-compatible mounts, lens tubes, and cage components. The adapters' design ensures that the C-lens is aligned with the optical axis when mounted into a lens tube. A 1/16" (1.5 mm) hex, nylon-tipped setscrew is used to press the C-lens fiber collimator against the two lines of contact created by the double-bored mounting hole. Additionally, each adapter has holes on opposing sides of the central bore for use with a spanner wrench. The SM05PT is compatible with the SPW908 spanner wrench while the SM1PT is compatible with the SPW801 and SPW909 spanner wrenches.

For women, one of the common types is Stress Urinary Incontinence (SUI). Check out our blog on Breaking Down Stress Urinary Incontinence: Causes and Solutions for more information on Stress Urinary Incontinence.

Holding your urine for too long can weaken the bladder muscles over time, which can lead to problems such as incontinence and not being able to fully empty your bladder. Additionally, holding your urine for extremely long periods of time can also cause urinary tract infections due to bacteria build-up.

If you find you cannot hold your bladder any longer, this is known as incontinence. There are many types of incontinence and conditions that could cause incontinence.

Click on the Pair Performance icon in the table below to view experimentally measured coupling efficiency data for the collimator pair as a function of the spacing between the collimators. Although the optimal working distance will slightly deviate for any two individual collimators due to small manufacturing variations, these slight deviations do not significantly affect pair or individual performance. This is evidenced by the data given below, which was taken with randomly selected collimators. To achieve the best possible coupling, we recommend mounting both collimators in kinematic adjustable mounts, such as the POLARIS-K05T6 Mirror Mount with SM05PT Adapter, sold below, for final alignment. All specifications, including beam diameter, beam distance, and pair insertion loss, are guaranteed at a working distance of 100 mm for a collimator pair.

Many women often ask the question “How often should I pee?” For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times a day can also be normal if that person is healthy.

For this reason, Thorlabs suggests epoxying the threaded fiber collimators into the threaded mounts if that mounting mechanism is preferred.

In this demonstration, the first fiber is single mode. The optical power incident on the second collimator, as well as the power output by the second fiber, are measured. When the second fiber is multimode with a 50 µm diameter core, alignment resulted in 91% of the power incident on the second collimator being measured at the fiber output. This value was 86% when the second fiber is single mode. Some differences in collimator designs, and their effects on the characteristics of the collimated beams, are also discussed.

Two collimators, inserted into a fiber optic setup, provide free-space access to the beam. The first collimator accepts the highly diverging light from the first fiber and outputs a free-space beam, which propagates with an approximately constant diameter to the second collimator. The second collimator accepts the free-space beam and couples that light into the second fiber. Some collimation packages, including the pair used in this demonstration, are designed for use with optical fibers and mate directly to fiber connectors.

Over two-thirds of women over 70 urinate at least once per night, and up to 60 percent go twice or more each night. It’s very common for most people to wake up once a night, and it becomes more common as you get older.

Therefore, it can’t hold as much urine as before. In women, this can be due to weakened muscles that cause the bladder or vagina to fall out of position (prolapse).

Working your pelvic floor can help with bladder control by strengthening the pelvic floor muscles that are responsible for closing your urethra and keeping urine safely in your bladder until it’s time to go.

INNOVO’s patented pelvic floor exerciser delivers 180 perfect Kegels per session, while you sit back and relax, and let INNOVO do all the hard work.

Adapters for the external thread are available (AD1109F) that allow the user to thread the fiber collimator into a mount.

How to collimate light from afiber

Liquids typically leave your stomach quickly. For example, after you drink a glass of water, it's estimated that only 50 percent of it will be left in your stomach after 10 minutes.

Ideally, 100% of the light emitted by the first fiber would be coupled into the second fiber, but some light will always be lost due to reflections, scattering, absorption, and misalignment. Misalignment, typically the largest source of loss, can be minimized using the alignment and stabilization techniques described in this video.

Try to drink at least 1.5 – 2 liters (6-8 glasses) of fluid each day. When you are not drinking enough, the bladder gets used to holding smaller amounts of urine and can become sensitive.

Thorlabs' FiberBench, which can accommodate pre-aligned FiberPort collimators and allows modular optical components to be placed in the beam path, is offered for modular fiber/free-space setups.

When your urine reaches that point, your brain receives a signal that you need to pee. This actually happens when your bladder is only a quarter of the way full.

A healthy bladder can hold about 2 cups of urine before it's considered full, so how long does take to pee after drinking water? For the average urine output, it takes your body around 9 to 10 hours to produce 2 cups of urine.

How long it’ll be from drinking to peeing depends upon how well your body is hydrated. If you’re dehydrated, a glass or two of water will quench your thirst but you may not need to pee for hours after.

As you age, your kidneys and bladder change, which can affect their function. The elastic tissue stiffens and the bladder stretches less.

C-Lenses and GRIN lenses are both cylindrical lenses used for fiber collimation; however, while a GRIN lens has a flat face, a C-lens features a curved face like a traditional convex lens (in this case with a 1.8 mm radius of curvature). Refracting light in this way allows for longer working distance collimators with lower insertion loss than our GRIN collimators for applications requiring more involved free-space beam manipulation. For Thorlabs' complete selection of fiber collimators, please see the Collimator Guide tab.

We’ve all had to hold our bladder for one reason or another, but the human bladder is only designed to hold a set amount of urine, otherwise getting into the “holding habit” can be dangerous.

Normal bladder volume by age changes over time. For example, children under the age of 2 can hold about 4 ounces. For children older than 2, the capacity can be found by dividing their age by 2, then adding 6. For example, an 8-year-old child can typically hold 10 ounces of urine.

Collimator Pair with Free-Space BeamOur C-lens pigtailed collimators are designed to be used in pairs, with a free-space beam between the lenses (see photo to the left). This free-space beam can be manipulated with many types of optics prior to entering the second lens. The collimators should be placed with a spacing of 100 ± 10 mm (working distance) between the front lens surfaces for maximum coupling efficiency. When used within the specified working distance and mounted on tip-tilt mounts as described in Free-Space Coupling, above, typical insertion losses of less than 0.2 dB are possible.

Thorlabs offers pigtailed fiber collimators that use C-lenses. These C-lens collimators feature a Ø1.8 mm clear aperture and are coupled to SMF-28 Ultra single mode fiber. They are designed to be used in pairs, with a free-space beam between the lenses, and can also be used individually. We offer models centered at 1550 nm with a choice of an unterminated scissor-cut fiber end, a 2.0 mm narrow key FC/PC connector, or a 2.0 mm narrow key FC/APC connector.

Manual pelvic floor exercises are effective, but it can be difficult to know if you’re doing them correctly and results can take a while to show.

You should pee as soon as you feel the need to go. If you have the urge to pee and you think you’ve put at least two cups of liquid into your system, it’s definitely time to go.

When you are well hydrated, the kidneys will efficiently expel urine, which may happen after drinking just one glass of water, meaning you may have to rush to pee after ten or fifteen minutes.

Normal urinary frequency depends on how much fluid you drink in a day and the types of fluid that you drink. It also depends on if you’re taking medication known as diuretics that can cause you to go more often. How healthy and active you are can also have an influence, and to some extent, your age.

For both packages, Thorlabs typically suggests the use of an adapter with a nylon tipped set screw that holds the barrel against a two line contact.

Free-Space CouplingWhen using C-lens collimators to couple a free-space beam into a fiber, precise alignment is needed for good coupling efficiency. We recommend using a kinematic tip and tilt mount and lens tube adapter, paired with an XYZ adjustable platform (such as ourPOLARIS-K05T6 Mirror Mounts, SM05PT Adapters, sold below, and MT3 XYZ Translation Stages), or our 6-axis kinematic mount paired with a lens tube adapter (Item #s K6XS and SM1PT, sold below).

If you have the urge to go to the restroom and it has been at least three hours since your last trip, it’s also probably time to go. Don’t go just because you think you should, but really learn to listen to your body.

However, the use of these adapters results in a stack up of threaded interfaces (threaded fiber connector, threaded collimator, and threaded adapter). As a result, it is possible that unscrewing the fiber connector could inadvertently loosen another thread interface and create an unknown source of instability in the setup.

If you find that you can’t make it to the bathroom in time, you might want to gage what you’re drinking and how much of it. You could be overstimulating it in other ways; caffeine, fizzy drinks, artificial sweeteners, alcohol, tomatoes and citrus can all trigger an overwhelming urge to go.

When we hold our urine by contracting the sphincter against an already strained bladder, the bladder wall can thicken and break down the normal one-way mechanism of urine flow from the kidneys into the bladder. This can increase the risk of infection and lead to long-term kidney and bladder issues.
