Hamamatsu製サイドオン型光電子増倍管(PMT)用アダプター
- Light-Tight Design Securely Holds PMT via Threaded Retaining Collar
- Compatible with SM1 Lens Tube and 30 mm Cage Construction Systems
- Post Mountable via 8-32 (M4) and 1/4"-20 (M6) Taps
The PXT1 housing centers the PMT active area along a beam path built using our SM1 lens tubes and 30 mm cage system.

概要
- SM1ネジ穴の中心に光電子増倍管(PMT)の受光面
- 光軸はケージによって決められ、またレンズチューブとも適合するためアライメントが容易
- PMTはPXT1/Mの筐体に取付けることで遮光可能
- レンズやフィルタはSM1レンズチューブ内に取付けることで光路の遮光が可能
PXT1/Mを使用すると、Ø1-1/8インチバレルのHamamatsu製サイドオン型光電子増倍管(PMT)と、当社のSM1レンズチューブおよび30 mmケージシステムを遮光された状態で接続することができます。この筐体を使用すれば、PMT用に独自のアダプタープレートを設計する必要がありません。
深さ9.5 mmのSM1内ネジを使用して、当社のØ25 mm~Ø25.4 mm(Ø1インチ)レンズチューブに接続できます。4つのØ6 mmの穴にはケージロッドを取り付けることができ、その穴間隔は30 mmケージシステムに対応しています。PXT1/Mの本体には、ポスト取付け用としてM4タップ穴が2つとM6タップ穴が1つあります。
PMTをPXT1/Mに差し込むには、まず固定用カラーを外します。下の図のように、PMTの受光面をPXT1/Mの筐体に滑り込ませます。本体内部はOリングにより遮光されます。固定用カラーを取付けることでPMTが固定され、さらにもう一つの遮光用シールも取付けられます。
PXT1/Mは、Ø28.6 mmの円筒形の外側にウィンドウが付き出ているタイプのPMTには対応していませんのでご注意ください。

PMTs usually have a metal magnetic shield case around them to protect the PMT (which is sensitive to interference from magnetic fields) from external mag fields. The standard Hamamatsu E989 shield case has a diameter of ~ 35 mm, so the PXT1 housing in its current form can only be used with an unshielded PMT.
I cannot find the material that the PXT1 is made from in your literature so I am not sure if it has magnetic shielding properties. Maybe you need to introduce a model with a wider barrel to allow the Mag shield casing to be included. cdolbashian

 (posted 2020-09-21 03:13:59.613) Hamamtsu R9182-01 is marked as compatible with the PXT1 product. However, in the case of R9182-01, it seems that it will not fit into the PXT1 product because it has an insulation cover. I really want to know if R9182-01 is compatible with PXT1. llamb
 (posted 2020-09-25 08:42:13.0) Thank you for contacting Thorlabs. The insulation cover on Hamamatsu's R9182-01 PMT would need to be removed for fitting into the PXT1. While Hamamatsu generally doesn't offer support on their PMT after that cover is removed, doing so will indeed allow it to be compatible with the PXT1. The outermost tube can be easily peeled off by making a cut with a blade. Then, the paint inside can be washed off with water. In the case of R9182-01, if water gets in through the gap of PMT body and base part, it may cause a short circuit, so caution will have to be used if you choose to remove the insulation cover. I have reached out to you directly as well to discuss this further. david.hill

 (posted 2017-08-03 12:11:29.0) Hello, thank you for contacting Thorlabs. Looking at both drawings, it appears that that PMT has a larger diameter than our housing is designed to hold. I will reach out to you directly to discuss your application. sdmt99

I have a Hamamatsu H10723 PMT which doesn't fit with your PMT housing. Maybe thorlabs could consider developing housings for the kind of PMT I mentioned? jlow
