You can now measure 8 independent thermocouples (C,E,J,K,T,R, & S types)
simultaneously with your PC using either DOS or Windows at low cost.
Temperature monitor plugs directly into serial port of PC for direct
display of temperature vs. time in either tabular or graphic format with
data storage to disk. The monitor comes complete with software program
for PC. For further details contact Lazar Research Labs. Inc. at

Did you try Kaiser Optical in Ann Arbor Michigan? They design and manufacture
holographic optics and filters. They do have filters for the visible and
near-IR regions. I know they have notch filters for the 488 nm and 785 nm laser
lines. They use them in their Raman systems.
