NEW!! Refractive Index Measurement System from UV Range to Near-IR Range
Features
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.
Applications
Angular measurement of transparent samples, such as new materials and glass, across the UV, visible, and near-IR ranges.
Extensive Options
Variable to user-defined wavelength specifications by adding a laser diode or other light source.
