特長

回折格子または長方形ミラーを Ø25 mm～Ø25.4 mm(Ø1インチ)ミラーマウントに取付け
安定な3点でキネマティック取付け
高さ60 mm以内の光学素子に対応可能な3種類をご用意

このシンプルで汎用性のあるアルマイト加工されたアルミニウム製の回折格子用アダプタは、超安定型キネマティックミラーマウント POLARIS-K1Eを含む当社のフロントローディング方式でネジ切り無しのØ25 mm～Ø25.4 mm(Ø1インチ)ミラーマウントに対応しています。高さ60 mm以内の長方形光学素子を、それぞれ対応するモデルに取り付けることができます(Table 1.1参照、ただし高さ20 mmの光学素子を取り付ける際には、KGM40を使用する必要がありますのでご注意ください)。

回折格子および長方形ミラーの取付けは、アダプタの上方および下方にあるクランプを光学素子の高さに合わせてスライドさせるだけで簡単にできます。このクランプは溝に沿ってスライドし、マウントの後ろ側にある2つのM3ネジで位置を固定します(Figure 1.2参照)。 3点キネマティック取付け機構は、底部の2線の接触と上部の板バネの接触から構成されています(Figure 1.3参照)。加えて、上方のクランプにある先端がナイロン製のロック用止めネジによって保持力が強化されています。

Table 1.1 Grating Compatibility
Item #	Grating Height	Grating Width	Grating Thickness^a
KGM20	< 20 mm	12 mm (Min)	4 - 8 mm
KGM40	20 - 40 mm	18 mm (Min)	5 - 10 mm
KGM60	40 - 60 mm	32 mm (Min)	6 - 12 mm

厚さの最大値にご注意ください。この値以上の厚さの光学素子を使用すると、十分に安定性を保持することができません。

Hello, is there a gap when fully closed? I'm not sure which directions the specs refer to as height, width, and thickness. I'm trying to use this to clamp down on a 1 mm thick piece of metal. Is there another product better suited?

Thank you for reaching out to Thorlabs. These mounts are unsuitable for mounting items less than 4mm thick. I have reached out to you directly to discuss possible alternatives from our product line.

Hello, an SM1 threaded KGM mount would be a nice varient for combining with SM1 threaded mounts like the K6XS, for example. The SM1-smoothbore adaptor leaves a lof of offset. Kind regards, James Good

Hello James, thank you for your feedback. We will consider offering such an item in the future.

Hi, i couldn't find information regarding the mount material. Is it vacuum (10-7mbar) compatible? Thanks.

Response from Chris at Thorlabs: Thank you for using our feedback tool. The material of the KGM series of grating mounts is black anodized aluminum, which is not a material which we would say is vacuum compatible. We have stripped the anodization in the past to provide a custom vacuum compatible version. I will contact you to discuss this further.

Response from Tim at Thorlabs: Thank you for contacting us! We would recommend using the KGM40 for a substrate exactly 20mm tall.

Hi, would you recommend the KGM20 or KGM40 for a substrate exactly 20mm tall?

Response from Javier at Thorlabs to jahan.dawlaty: Thank you very much for your feedback! I will share your comments with our mechanics department and keep you informed of all the details regarding this product.

It would be nice if this product (Kinematic Grating Mount Adapters) also allowed for grating rotation. Grating rotation (along with tip and tilt) is necessary for proper alignment.
