I'm having an issue with a refractometer I bought several months back. Its always had this problem, I just gave up on it in frustration soon after I bought it, but I bet this forum can help me with the problem.
Essentially, the line between blue and white is *extremely* fuzzy. So fuzzy in fact that its not possible to make even a general estimate about what the reading might be.
The actual scale is in-focus, so its not that the optics are totally screwed up. I've also tried using a single bright light source, which also doesn't help. I've made sure that there are no air bubbles in the sample and that the plate is completely covered. I've let the device sit for a few minutes before taking the reading, and it shows no apparent improvement.
It almost seems like something is not aligned properly internally.
Any suggestions? Is it lemon?
