Huanyu Optical Tilt and Rotation Stage 2.6 inches Precision angle stage 2-axis Manual Angle adjustment platform Two-dimensional 3°Tilt Table Thread Secondary Rotary Tilt Table

I bought this stage to use in my lab to tilt a very sensitive setup for 5th harmonic generation (I am a laser spectroscopist). Compared to the "high precision" rotation stage from typical scientific equipment vendors (Thorlabs not to name them...) this one is substantially better! It completely put the more expensieve stage to shame!!! Full tuning of the 5th harmonic on the crystals with the Thorlabs stage happened in less than 1/10 th of a turn on its micrometer screw. Not much optimization possible there. By contrast, this Huanyu stage gave me more than 1 full turn of its rotation screw to fully tune the same range. No contest! Plus, this stage has another tiling axis which the Thorlabs one just didn't offer. So far, this is a great purchase!
