Being able to thermally stabilize an LED is useful for any sort of high accuracy sensing application. I was looking for an LED module that would incorporate a thermistor and something to adjust the temperature like a TEC.
I was able to find this company: https://www.laserscom.com/products that have the three packaged together with a fiber optic connector coming off of it and am wondering if I can find more convenient options (In terms of location/availability). But overall, I'm finding it surprisingly hard to find anything like it. I tried looking in the different optoelectronic categories at digikey and looking at the product list for some big LED companies but really didn't find anything like it.
It seems like something that would exist based on reading application notes and datasheets of PID controllers intended to work in tandem (http://www.analog.com/media/en/technical-documentation/data-sheets/ADN8835.pdf). Am I just not using the right search terms to find it or are LED+thermistor+TECs typically bought separately and put together?
