Hi all,

I'm looking for some dual-channel phototransistors or photodiodes in the side looking packages with shutters and very smalll gap between these shutters. I found out only dual-channel phototransistor PT2559B from Everlight. Does anybody know any alternatives or any others?

Thanks.

- the mouse - I need this photo-components in the serial production and buying of the mouses is not very profesional.... What do you mean?

- Agilent - I tried to look over theirs web sites but I didn't find anything such I need. Do you have any tips???

Thanks

Thanks Ratburn, but there are not any dual-channel photodetectors in this document and also on theirs web.
