Adjustable Collimating
Lens Holder
 The 74-ACH Adjustable Collimating Lens
Holder 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 sampling optics such
as our FHS-UV
In-Line Filter Holder. 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.
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).
