Angle and Refractive Index Measurement System in Visible Range
Features
The high-accuracy encoder achieves ±1" angular measurement accuracy and ±0.00001 refractive index measurement accuracy. The angle measured by the encoder is directly displayed on a digital counter. High-accuracy ball bearings used for all rotary sliding parts ensure smooth and accurate rotation. The color-corrected objective lens eliminates the need for readjustment when the measurement wavelength changes.
Applications
Precise angle measurements for prisms, etc.
Refractive index measurements for transparent materials, such as glass.
