74-ACH Adjustable Collimating Lens Holder
The 74-ACH A DJUSTABLE C OLLIMATING L ENS H OLDER is a versatile assembly for mounting lenses at multiple
positions, and is especially useful for transmission measurements of large or thick samples not easily
accommodated by other sampling optics such as our FHS-UV and FHS-VIS In-line Filter Holders.
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 1" apart starting 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 5/32" hex-head
wrench (not included).
" The bars can be set far enough apart to accept samples up to ~10 cm thick.
" The base is scored at ½ cm intervals as a path length guide.
