Shadow cast carbon replicas of diffraction line gratings (spacing 462.9 nm) which are used typically for calibrating electron-optical magnifications up to the x80,000 to x100,000 range.
Rulings of 2160 lines/mm, ruled at 90° to one another, give additional accuracy to magnification checks and aid in checking distortion. These replicas should be used with care, avoiding excessive exposure at high probe/beam currents.
The AGS106L standard for calibration, provides a double-check of the accuracy of magnification calibration and is particularly useful for higher magnifications. The latex sphere size is 0.261µm and the grating replica is 2160 lines/mm. Supplied on a 3.05mm grid.
Some or all of these products require refrigeration storage between 2-8˚C. As a result, and to retain the integrity of the product, we will not ship on Fridays or where we cannot confirm a next day delivery. Additionally, we cannot accept customers returns for these products if ordered in error as the storage has been outside our control.
LEAD TIMES: Average Lead Times are shown individually in days for any products not currently in stock. Whilst we are working closely with our suppliers to minimise the impact of global supply chain issues, and regularly update our product prices and lead times, some are subject to change due to supply chain fluctuations.
Delivery is calculated at the checkout, please see our delivery and returns page for more information.
