Diffraction Standard- Camera Length AluminumThe nominal value of the effective camera length of an EM operating in the selected area mode is not sufficiently accurate for calculations of lattice spacing. The actual value of camera length must be calibrated at the same accelerating voltage and objective lens setting by reference to a known substance with well defined diffraction spacings. A normal specimen is evaporated film of aluminum with a thickness of around 31nm. Very small crystallite

This is a well constructed wallet and they used good material
Color: Coffee Brown, Style: Casual
I really like the leather, and all the compartments for the credit cards and two IDs. The only issue I’ve had with this wallet is it’s just a little too high. Should be a quarter of an inch shorter because it’s awkward putting it in and out of your your pocket.

Fit in pocket
Color: Dark Gray, Style: Classic
Bought as a gift. My husband really liked it, held all his cards. The leather was very nice. Color was very soft gray and I liked it better than the normal black or brown. Wallet fit well into his back pocket.
