retroflectors
(OP)
looking for sheet retroflectors. all the stuff we've found is for the safty/automotive industry and not of good enough quality for our app. an body know of anyone making better stuff for 'scientific' or display applications?
thanks.
thanks.

This is a visual imaging app. where an image from an LCD is reflected and magnified several times. Right now the retrofeflector causes the image to be quite 'hazy' or soft. This, presumably, is caused by the ideally sharp angles of the corner-cube detail being slightly rounded or imperfect which disperses the incident light in a random manner. At the end of the day we need material where this geometry is as good as possible and the 'peaks and troughs' of the individual facets are as sharp as possible. Right now we're using a 'sign' type material from Reflexite.
Any help would be appreciated.

Is there no other way to accomplish what you need? What are the dimensions involved, IFOV's, etc.?
Based on the limited information and some outright guessing, you'd better performance than obtainable from any commercially inexpensive retroarray. Both the surface intersections and the actual angles of intersection are going to impact your application.
I'm having a lot of trouble imagining where you might use a retroreflector, as there are many applications where a retroreflection is more easily obtained by using a plane mirror that's aligned in-situ.
