![]() Direct metrology provides higher stability and linearity compared to inferred metrology feedback - usually based on piezo resistive strain gauges, a technique also available from PI for entry level piezo nanopositioners.īest in Class Design, Millisecond Step & Settle, Sub-Nanometer Precision PIHera closed-loop stages are equipped with direct-metrology capacitive sensors and provide resolution down to the sub-nanometer-level, in a compact, FEA optimized package for high stiffness and long lifetime. Travel ranges start at 50µm and go all the way up to 1,800µm (1.8mm) - a record for flexure guided piezo stages.Ī total of 60 standard variations are available, including closed-loop, and UHV compatible versions.ĭriven by PI's proprietary PICMA® piezo ceramics (tested by NASA/JPL for 100 billion cycles and employed on the Mars Rover), PIHera piezo stages have unique properties especially important in long-term research and industrial applications.Ĭlosed-Loop, Direct- Measuring Feedback Sensors PIHera stages come in single axis (horizontal and vertical), two-axis (XY), and XYZ combinations. The PIHera flexure positioner series offers the largest variety of travel ranges and options of any high precision piezo nanopositioning stage currently available. Largest Variety: 60 Models / X, XY, Z, XYZ / 50 to 1800 µm Travel Ranges Tax advice is not provided by JPL and supplier compliance or exemption questions should be referred to the supplier’s tax preparer.PI (Physik Instrumente) L.P., a leading manufacturer of nanopositioning and precision motion-control equipment for nano-biotechnology, life science and photonics applications, provides the PIHera family of compact X, XY and Z flexure-guided piezo nanopositioning stages, offering record travel ranges to 1.8 millimeters. Questions about the JPL tax reporting and withholding process please direct to the JPL Subcontract Manager for your PO or Subcontract. JPL endeavors to simplify the process while managing compliance. Below you will find reference links to the taxing authority sites and regulations. Jet Propulsion Laboratory (JPL), as a division of California Institute of Technology, is subject to tax reporting and withholding in compliance with CA State Franchise Tax Board and U.S. To verify if multiple projects and/or tasks pertain to your subcontract, please follow up with your subcontract manager. We require the project and task numbers for subcontracts with multiple projects and/or tasks so we can properly allocate billed costs. Why do I include the subcontract project and task numbers? A Pro forma invoice is an estimate invoice from the seller before shipment or delivery of goods and used as preliminary invoices with a quotation. A Pro forma invoice does not meet JPL’s invoice requirements. IMS will review your submitted W-9 form as a cross-reference.Ĭan I submit a Pro forma invoice for payment? The company name on the invoice should correspond to the legal company name. Progress payment and deliverable with SF1443Ĭost Reimbursable with an Educational Institution (CREI)įor Purchase Order (PO) invoices and Consultant Service Agreement invoices send to: Subcontract invoices send to: attach only one invoice per email submission with any applicable back up documentation in pdf file format.ĭoes the company name on the invoice have to match the company name on the Purchase Order or Subcontract? Date of invoice and when it was sent to JPL.Please have the following information on hand so we can better assist you. We want to make sure we provide you with excellent customer service. Please see Forms & Instructions section linked above for requirements.įor more questions, please visit the FAQs section linked above. Please ensure invoice requirements are met before submitting otherwise invoice will be rejected. Sufficient back up documentation submitted with invoice (documents required for payment).Modification issued to extend the Subcontract or SWO end date.Amount billed is within the Subcontract Work Order (SWO) value.Avoid sending duplicate copies of the invoice.Re-bill by line item and at unit prices on PO.Quantity billed is the quantity received.Please send Proof of Delivery to us at Verify good(s) and service(s) are authorized on PO.
