This is my first time reading sci.electronics: I hope these questions have not been asked before. I am building a light meter. Can anyone recommend a visible light phototransistor for this purpose. I have only come across phototransistors that work in the IR range. I noticed my camera uses a "Silicon Blue Cell". Is this a phototransistor or ...? Are blue diodes available? If so, who makes them. Any suggestions for Canadian distributors? Any help would be most appretiatied, Linas Dauksa ieee@ecf.toronto.edu or dauksa@ecf.toronto.edu
