手動ビームシャッタSM1SH1は便利なラベル付きスイッチで、光学アセンブリ内にビームを伝搬させる際に使用できます。このようなレバー作動シャッタは、精密戻り止め機構によって開閉の両方の位置でしっかりと固定されます。シャッタを開けた時の有効径はØ7.2 mmです。
こちらのアルミニウム製シャッタの片側にはSM1内ネジ、もう片側にはSM1外ネジが付いているので、当社のレンズチューブシステムでの使用に適しています。シャッタの内ネジ側(上のFront View参照)にはシャッタの機構が内蔵された金属プレートがあり、外ネジ側はDelrinが露出しています。入射ビームに対しては金属プレート側を向けることをお勧めいたします。

なお、シャッタSM1SH1を30 mmケージシステム内でご使用になることはお勧めいたしません。ケージロッドがシャッタのレバーアクチュエータに接触してしまいます。ケージシステム内でご使用になる場合は、上の写真のようにシャッタを1番端の部分に取り付けることをお勧めいたします。

(posted 2017-04-19 21:08:59.097) Hi,
we're using the SM1SH1 shutter to contain the output beam from our Coherent RegA (regenerative amplifier) with a pulse length of ca. 30fs and a CW-equivalent output power of ca. 1.5W, and it works very well; the shutter hardly feels warm, and several days of constant usage haven't left a mark on the shutter plate itself.
However, this is true only if the shutter is built in metal-plate first. The fact that one of the plates enclosing the shutter mechanism is actually plastic is somewhat surprising, and gave us a nice cloud of blue smoke.
An all-metal version of the shutter, possibly even a high-power version with steel plates, would be a nice addition.
The existing version could be improved by simply printing arrows on the outer ring designating the preferred (i. e. non-smoke-producing) travel direction for high power/short pulse beams. tfrisch

(posted 2014-06-27 08:19:09.0) Response from Mike at Thorlabs: Thank you for your feedback. The SM1SH1 Threaded Beam Shutter can be post mounted using the SM1RC Lens Tube Slip Ring found here http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1533&pn=SM1RC. The SM1RC contains a bottom-located 8-32 tap that allows it to be directly connected to any of our 1/2" diameter posts found here http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1266. Based on this feedback we have updated our website to include information on how the SM1SH1 can be post mounted. jjurado

We currently do not have a precise laser induced damage threshold value for this shutter; however, since the shutter material is aluminum, the power required in order to ablate it is in the order of tens to hundreds of Watts. david.merino
(posted 2011-05-09 17:11:26.0) What is the maximum power from a parallel beam that this shutter would handle?
Thanks Javier
(posted 2010-06-10 09:43:37.0) Response from Javier at Thorlabs to jc7: yes, the lever would be blocked by the cage rods. We will look into designing a cage compatible shutter based on the SM1SH1. I will contact you directly with more details. jc7
(posted 2010-06-09 17:39:40.0) Hello, Would the lever of the SM1-Threaded Manual Beam Shutter (SM1SH1) be blocked by the rods of a 30mm cage system? Thank you, James. |
