Application Tips
The 74-ACH consists of an anodized aluminum base and adjustable mount bars.
Each bar has four 3/8-24 threaded holes, spaced 2.54 cm (1") apart starting 2.54 cm (1") from
the top of the bar, to accommodate collimating lenses.
The bars can be adjusted on the base by loosening two 10-32 threaded set screws with a
0.40 cm (5/32") hex-head wrench (not included).
The bars can be set far enough apart to accept samples up to ~10 cm (3.94”) thick.
The base is scored at ½ cm (0.20”) intervals as a path length guide.
