Crossline Diffraction Grating

500nm Magnification Calibration Diffraction Grating Replica

Carbon replica with Au/Pd shadowing on a cross line grating with well-defined trench type grooves. Pitch or "d" spacing for parallel line grating is 500nm. The trench type groove makes it easy to measure the pitch. Typically, cross line grating is used up to 100,000x with 2,000 lines/mm in both directions. Instructions included. Made on a G400, 400 square mesh copper grid.

500nm Diffraction Grating Replica with Latex Spheres

Two-in-one; this standard for calibration provides a double-check of the accuracy of magnification calibration. It is particularly useful at higher magnification; up to 150,000x. The latex sphere size is 261nm and the carbon cross line grating replica with Au/Pd shadowing has a pitch or "d" spacing of 500nm or 2000 lines/mm. Replica has well-defined trench type grooves, which makes it easy to measure the 500nm pitch. Supplied on a G400, 400 square mesh copper grid.

Carbon replicas with Au/Pd shadowing of diffraction line gratings, parallel line, waffle pattern gratings. Made on a G400, 400 square mesh copper Gilder grid. Typically, parallel is used up to ~40-50,000x, while the waffle is used up to ~80-100,000x. Parallel line gratings are 2,160 lines/mm (54,864 lines/inch). The waffle is 2,160 lines/mm in both directions. Line or "d" spacing for parallel line grating is 462.9nm. Instructions included.
