Please review and confirm that your curves are updated and accurate. Can you tell me what weight these were and what stiffness they were. Thank you for pointing this out! Collimation packages with custom alignment wavelengths, operating temperature ranges, or vacuum compatibility are available by contacting. If focal shifts are present, coupling efficiency will be reduced and therefore so will the damage threshold. High power connectors and fiber would be needed for this application, and even with this, we can see that the third item of interest, the collimator itself, is still a limiting factor. I will contact you to discuss other ways to collimate your source. However maybe this message can save future generations from the same fate.
Although it is possible to use the collimator at any wavelength within the coating range, the coupling loss will increase as the wavelength is detuned from the design wavelength. We have contacted you to continue this discussion. Had I known that they were not labeled, I would have labeled them the moment I opened the plastic pouches! Applications include laser beam delivery systems, as well as coupling the output of a fiber into a detector. However, if you are planning to use this to couple into fiber, you will have some coupling efficiency which will reduce your power. Better yet, can you label them somehow acid-etch, ink, whatever? Response from Tim at Thorlabs: The short answer is no, I would not recommend this part for 40W. Response from Tim at Thorlabs: Thank you for your feedback! That may not sound like a long time ago in the storied history of golf, but that was actually when players began shifting from persimmon to metal woods.
Can you give me all technical information about the lens into the collimator? Thorlabs' metallic-coated Reflective Collimators are based on a 90° off-axis parabolic mirror. It would be helpful to have vertical scales that allowed the read to understand the residual reflectivity, and ideally the V-coats would have the same vertical scales. Please note performance specifications are guaranteed only when used with single mode fiber. Please contact to request a collimator aligned at a custom wavelength. The design wavelength and fiber are specified in the caption for each graph.
Although it is possible to use the collimator at detuned wavelengths, they will only perform optimally at the design wavelength due to chromatic aberration, which causes the effective focal length of the aspheric lens to have a wavelength dependence. Fiber Collimator Selection Guide Click on the collimator type or photo to view more information about each type of collimator. Can you please include little labels that contain the part numbers that we can adhere to the barrels of the collimators when we receive them? Whether you are collimating or coupling will also alter the damage threshold. Hello, thank you for contacting Thorlabs. Response from Buki at Thorlabs: Thank you for using our feedback forum.
Each collimation package is factory aligned to provide diffraction-limited performance for wavelengths ranging from 405 nm to 4. They are also useful for coupling light from laser diodes into fibers, coupling the output of a fiber into a detector, or collimating laser light. The one that looks believable is the 1064 nm coating with a roughly 0. These collimators also utilize epoxy. These collimators provide a variable focal length between 6 and 18 mm, while maintaining the collimation of the beam. Response from Tim at Thorlabs: Thank you for your recommendation.
Simulations of the theoretical divergence when using one of our standard collimators at wavelengths other than the design wavelength are shown in the graphs below. I need very high coupling efficiency. Divergence Angle Comparison The divergence angle can be estimated using the formula shown to the right, given that the light emerging from the fiber has a Gaussian intensity profile. Because these fiber collimators have no movable parts, they are compact and easy to integrate into an existing setup. What that means to the golfer is more energy transfer to the golf ball, yielding increased velocity and resulting in greater distance.
There are a few things we need to look at in order to determine the power handling capability. Underscores the importance of evaluating hard data. If there is ever a question of which product is best for your setup, please contact us at techsupport thorlabs. For other collimation and coupling options, please see our Collimator Guide tab or contact. Depending on your viewing angle and lighting conditions, the shafts can appear anywhere from a dark smoky grey to a mercury silver.
Would like to know which one was highest launch , spin, and dispersion? The result was a divergence angle of 0. We intend to use the collimator as a connection between an optical fiber and the input of an echelle spectrometer. Although this collimator is factory aligned for a specific wavelength, it has a low divergence angle over a broad range of wavelengths. One would then have to choose the closest focal length lens available. Please refer to the theoretical divergence plot for this collimator to determine if it is appropriate for your application. This divergence angle is easy to approximate theoretically using the formula below as long as the light emerging from the fiber has a Gaussian intensity profile.
I see the Recoils felt best, but was that because of the SmacWrap addition, or just the performance of the recoil technology. During the transition, I could feel the shaft loading in my hands, and the tip had a strong release at impact. Our reflective collimators are ideal for single-mode fiber. Introduction has been one of the top graphite shaft manufactures for over 25 years. Response from Tim at Thorlabs: Thank you for your feedback.
