500nm Diffraction Grating Replica with Latex Spheres PTFE over SS The pattern with the 350-400µmDESCRIPTION magnification calibration specimen 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
