Student Spectrometer

SEM-5701

 

DETAILS

Introduction:

 The Spectrometer is spectroscopic angle measurement instrument. It can be used for the angular measurements based on refraction, diffraction, interference or polarization.

We offers this high-quality spectrometer that allows students to perform accurate prism and grating spectrometry. High-quality, large-aperture optics produce sharp spectral images, while precision machining allows for precise rotation and accurate measurement.

Experiments:

  • Min-deviation measurement of prism based on principle of refractive, computation of refractive index and dispersion of the material by which the prism is made.
  • Wavelength measurement and demonstration of the diffraction phenomenon in interference experiment when in conjunction with the grating.

Features:

1. The large diameter lens barrel is continuous-zoomed by hand wheel.

 

2. Wide-range voltage power supply design, using 110-250V power supply or 3V battery box, and it is suitable for most of countries.

3. Use long-life and high brightness green LED to illuminate the view field.

Parameters:

  • Angle measurement accuracy: 1'
  • Collimator and telescope: focal distance 170mm, aperture Φ30mm, visual field 3°22’
  • Triple prism: angle 60°±5', material: ZF2(nD=1.67268, nF-nC=0.02087)
  • Ocular focal distance of telescope system 24.3mm
