特長

  • 内ネジ付きのターレットや対物ホルダ(レボルバ)に対応するM25 x 0.75外ネジ付きやRMS外ネジ付きのアダプタ
  • Bergamo®および Cerna®顕微鏡システムに対応するM32 x 0.75外ネジ付きアダプタ
  • Cerna取付けアームCSA2100に対応するSM2外ネジ付きアダプタ
  • 内ネジは当社製、Mitutoyo製、Olympus製、Nikon製、Zeiss製、Leica製の対物レンズに対応
  • 突き当て構造により顕微鏡対物ホルダ(レボルバ)に取り付ける際の締め過ぎを防止
  • 真鍮製

こちらの顕微鏡用真鍮製アダプタを使用すると、外ネジ付き顕微鏡対物レンズをRMS、M25 x 0.75、M32 x 0.75またはSM2の内ネジ付き対物ホルダ(レボルバ)に直接取り付けることができます。こちらのアダプタには、対物ホルダ(レボルバ)にアダプタや対物レンズを取り付ける際に締め過ぎを防ぐためのフランジが付いており、それにより対物レンズを適切な位置に保持するとともに、筐体内部の光学素子の損傷を防止できます。また、真鍮はアルミニウムよりも固いため、ネジの噛み込みが発生する可能性が低減されます。アダプタM32M32Sは、多くのM32 x 0.75ネジ付き対物ホルダ(レボルバ)の内ネジ部分が窪みの奥に切られていることから製作されました。TL10X-2Pのような直径の大きい対物レンズの場合、適切に嵌合させるにはより小さな直径のマウントが必要になります。各アダプタにはスパナレンチ用の穴またはスロットがあり、対物ホルダにアダプタをねじ込む際に調整機能付きスパナレンチSPW801を使用することができます。

ネジアダプタの全ラインナップは、ネジ変換アダプタのセレクションガイドをご参照ください。上記のように、顕微鏡対物レンズにアルミニウム製のアダプタを組み合わせて使用することは推奨しておりません。

Hi, Is it possible to receive a quote for an M34 external M25 internal adapter? Best regards Levin Hafa
Devin Porter  (posted 2022-03-07 20:37:54.29)
I have a nikon objective (M25 x 0.75 threading) that I am trying to use with a zeiss axiovert microscope (turret threading appears to be about 25 mm). Is there an adapter that we can use? Thanks, Devin
cdolbashian  (posted 2022-03-15 09:43:13.0)
Thank you for reaching out to us Devin. Threading in microscopy is often very specific to the model of the microscope and corresponding objective turret used. I have reached out to you to discuss the particular model of Zeiss Axiovert, and the objective threading therein. It is likely we do have a threading adapter for you although we first need to correctly identify the threading used on your microscope.

I want to use Olympus W20.32x0.706 (RMS) Objective to Nikon Microscope. Nikon objective have M25x0.75 thread. Please suggest the adapter for the same. Thanks

Hello, thank you for contacting Thorlabs. Unfortunately, we currently do not offer an internal RMS to external M25 x 0.75 thread adapter. We will consider looking into offering such an item in the future.

Hello. I'm looking for an adapter of 0.75 inch diameter to 1.0 inch diameter. The idea is to use Nikon objectives in a Zeiss microscope. Can you help me to decide which option is better? Thanks, Best regards, Andres Medina
YLohia  (posted 2020-09-18 02:28:21.0)
Hello Andres, thank you for contacting Thorlabs. Based on our direct discussion, in order to convert the M25 x 0.75 threads of the objective to the RMS threads of the microscope, you will need the RMSA2 adapter.
Tobias Noebauer  (posted 2020-08-31 21:00:44.693)
We keep having issues with this adapter getting stuck in a microscope objective thread. I think this is because of the two d=0.06in holes that go through the flange ring (the face with the markings). These holes have sharp edges on the opposite side of the flange ring, which get pressed against the microscope housing when the adapter is fastened. These sharp edges create extra friction that can get the adapter stuck quite firmly. Not even the spanner wrench tool can help in these situations, we have to use WD-40 and some special pliers. I would suggest not to drill these holes all the way through the flange ring but leave them blind. Thank you!

Hello Tobias, thank you for your feedback. We're always looking for ways to improve our products, so any thoughts on such matters are always appreciated. I have posted your suggestions on our internal engineering forum for further consideration.
