Optical Wavemeters

[Bryan]

I measure wavelength in the 600-1650 nm range, my Advantest TQ8325 has develope a malfunction & is no longer supported, curious what others are using?
Advantest did sell a Q8326 which I presume was a follow on model.  Anritsu made the MF9630A but it doesn't show up on their site, Agilent makes the 86120B, it appears current and there is a company called ADCMT that broke off from Advantest making the 8471 and I found another comapnay called Bristol Instruments that makes some.  Looking for any input regarding your experiences with support or other suggestions from similar products with support at present.  TIA.
