While I did find a little information in searching your site I am still unsure what to use in my application. I want to detect the (red) laser light hitting a screen or target. My questing is what is a good device to use, I read that photo diode is faster than a photo transistor. Can any one give me any part numbers to try?
Application Simple laser target, when the training pistol laser hits the target I need a fast detection. I will experiment with the final output later in this project, to start with I might just turn on a light. I also have realized that other indoor lighting may need to be filtered, I have knowledge of filters, I will later research this.
