Adjustment of the attenuation is achieved using the thumbscrew on the top of the housing.</p> <p>The attenuator is comprised of an input fiber, collimating lens, blocking device, focusing lens, and output fiber. By turning the thumbscrew, the blocking device is shifted into the beam path, blocking part of the free-space beam (refer to the schematic to the right). Then, a second lens is used to couple light into the output fiber. Therefore, by turning the screw, one can manually alter the coupling efficiency until the desired attenuation is obtained.</p> <p>All in-line PM VOAs have fiber pigtails with a &Oslash;900 &micro;m jacket and are available with 2.0 mm narrow key FC/PC- or FC/APC-connectorized fiber pigtails with the key aligned to the slow axis.

PM VOAs with other center wavelengths exhibit similar performance.&nbsp;Please note: changes in turning direction may cause a small offset in attenuator position due to backlash.</p> <div class="imgFloatRight" style="margin-right: 300px;"><a href="images/TabImages/PM_VOA_Attenuation_780.gif" onclick="return hs.expand(this, {wrapperClassName: 'highslide-no-border', spaceForcaption: 60})"><img src="https://www.thorlabs.com/images/TabImages/PM_VOA_Attenuation_450.gif" border="0" alt="PM VOA Attenuation by Turns" width="450" height="274" /><br />Click to Enlarge</a><br /><a href="images/TabImages/PM_VOA_Attenuation.xlsx">Click for Raw Data</a></div></div><div class="tab-pane" id="0BCB21C2-5C2D-40D9-9BDE-B95550718F4A-6162"><style>.smallestCTag { font-size: xx-small; } .smallCTag { font-size: small; } .mediumCTag { font-size: medium; } .largeCTag { font-size: large; } .largestCTag { font-size: xx-large; }</style><script type="text/javascript">function getdocuments(objectgroupid, divname) { var http = false; if(navigator.appName == "Microsoft Internet Explorer") { http = new ActiveXObject("Microsoft.XMLHTTP"); } else { http = new XMLHttpRequest(); } http.abort(); http.open("GET", "_ajaxDocs.cfm?objectgroup_id=" + objectgroupid, true); http.onreadystatechange=function() { if(http.readyState == 4) { document.getElementById(divname).innerHTML = http.responseText; } } http.send(null); }</script><script>$(document).ready(function() { $('input[name="SubmitAnonymously"]').on('change', function() { if ($('input[name="SubmitAnonymously"]').attr('checked')) { $('input[name="FirstName"]').removeAttr('required'); $('input[name="FirstName"]').val(''); $('input[name="FirstName"]').prop('disabled',true); $('input[name="LastName"]').removeAttr('required'); $('input[name="LastName"]').val(''); $('input[name="LastName"]').prop('disabled',true); $('input[name="EmailAddress"]').removeAttr('required'); } else { $('input[name="FirstName"]').attr('required','required'); $('input[name="FirstName"]').prop('disabled',false); $('input[name="LastName"]').attr('required','required'); $('input[name="LastName"]').prop('disabled',false); $('input[name="EmailAddress"]').attr('required','required'); } }); });</script><script language = "Javascript">function countChars(textareaId, counterId, max) { var count = max - document.getElementById(textareaId).value.length; if (count < 0) { document.getElementById(counterId).innerHTML = "<span>" + count + "</span>"; } else { document.getElementById(counterId).innerHTML = count; } }</script><br /><style>.feedback-tab-title { font-size: 18px; margin: 0 0 0 20px; } .feedback-tab-title-banner { padding: 0 5px; } .feedback-tab-heading { font-weight: bold; padding-bottom: 5px; } .feedback-tab-container { padding: 2% 20px; margin: 20px 0; background-color: #ccc; border-radius: 10px; font-family: arial, helvetica, sans-serif; } .feedback-tab-row { background: #eaeaea; padding: 1%; border-radius: 10px; box-shadow: 1px 3px 10px #888; border-top: 10px solid white; } .first-row { margin-bottom: 20px; min-height: 88px; text-align: center; padding-left: 0px; } .first-row .item:not(:last-child) { border-right: 1px solid #dedede; min-height: 88px; } .feedback-tab-email-textbox { width: 200px; } .feedback-tab-parts-container { margin: 10px 0; } .feedback-tab-useful-scale { margin: 10px 0; } .feedback-tab-captcha { margin-top: 20px; } div .feedback-tab-captcha-text { margin-bottom: 15px; } .feedback-tab-email-optional { font-style: italic; padding-top: 7px; } .feedback-tab-contactme-checkbox { margin-top: 5px; } textarea { resize: vertical; }</style><form action="feedback_submit.cfm?form=product" name="userFeedbackFormylrfez" method="POST" onSubmit="return catchEmptyForm('userFeedbackFormylrfez','CustReply'); "><input type="hidden" name="objectgroup_id" value="6162"><input type="hidden" name="redirectURL" value="NewGroupPage9.cfm?objectgroup_id=6162" /><div class="feedback-tab-title"><strong>Please Give Us Your Feedback</strong></div><div class="feedback-tab-container bsc"><div class="container-fluid"><div class="row"><div class="col-xs-12 feedback-tab-row first-row"><div class="col-xs-5 item"><div class="feedback-tab-name"><span class="feedback-tab-heading">1.

Both the connectors and the internal fiber terminations are using similar epoxies and will see similar thermal related limits due to the total power. At some point the epoxy will soften which can lead to drift of alignment, which increases the loss, and results in damage to the device.
