[Laser] Wavelength Sensor

[Terry Morris W5TDM]

This seems to be a handy little photodiode based sensor that can determine 
wavelength with a spectrial resolution of .01 nm. The sensor is from Pacific 
Silicon Sensors and is avalible from Mouser.
They are a little pricy at $48 each. They also have a sensor on evaluation 
PCB but didn't see the price for evaluation board.  Also chech out Pacific 
Silicon Sensors catalog, they have Si diodes with shifted peak wavelengths 
from 600nm to the standard 900nm. Also probably a little expensive.

Just researching detectors and ran across these, thought they were 
interesting.
