Angle and Refractive Index Measurement System from UV Range to Near-IR Range
Measures refractive index over the UV, visible, and near-IR ranges.
Measured angle is clearly displayed on a dedicated counter.
Minimum deviation method offers highly accurate refractive index measurements.
Excellent ±1" angular measurement accuracy. The 1/2-ratio gear system and photoelectric detection easily determine the angle of minimum deviation.
Angular measurement of transparent samples, such as new materials and glass, across the UV, visible, and near-IR ranges.
Variable to user-defined wavelength specifications by adding a laser diode or other light source.
