Specifications for Iodine Cells

In addition to the specifications below, see the attached drawings. The cells shall be manufactured with a stopcock and shipped to Langley. Langley will set the iodine density in the cells, and then send the cells back to the vendor for pinch-off of the stem+stopcock assembly.

Item 1: Iodine cell with dimensions 1.50” diameter x 4.00” long (length includes windows) Cell Material = Quartz Diameter = 1.50" +/- 0.2mm Length = 4.00” (length included windows) +0/-0.08” Window Type = Flat Window Angle = 7 degrees +/-1 , windows angles parallel to each other Window Diameter = 1.50” +/- 0.2mm Window Thickness = 0.125" +/- 0.1mm Window AR-Coating = AR V-coat at 532 nm on both sides of windows Fill Stem = With glass stopcock and high-temperature O-ring gasket Quantity = 6

Anti-reflection coating for all windows All windows shall have an AR-coating for 532nm with AOI range 0 to 12 degrees optimized at 7 degrees for R< 0.5, applied to both sides of the windows.

Iodine Cell General Specs (before pinch‐off)

Max stem length ~ 1.5‐2” Stem inner diameter shall not narrow appreciably near the cell; stem diameter needs to stay as uniform as possible along entire length.

Note orientation of stopcock with respect to cell orientation.

(See next page for detailed dimensions of cell)

Stopcock material = glass

All iodine shall be below the closed stopcock; no iodine in the cell.

Use high‐ temperature gasket only.
