spectrometer

This instrument adopts the optical glass dial and cursor, with reading convenience, high precision, stable structure, flexible operation, such as the adjusting range is big, multi-purpose features.Except for the teachers and students in colleges and universities for basic physical optics experiment, also available for other factories, scientific research departments for the use of Angle measuring instrument.

use

1

On the surface of the prism and other mirror Angle measurement;

2

Prism refraction Angle measurement;

3

Measure the minimum deviation Angle and the refractive index of transparent materials;

4

Measuring wavelength;

5

The determination of prism dispersion rate.

structure

This instrument is the center of the shaft adopts half rolling cylindrical shaft system, automatic centering, high precision, responsibly and shaft jacket plate and cursor.Dial with the axis of rotation (with objective table linkage).The cursor with the telescope tube shaft rotation around the center.Calibration and cursor are equipped with a micro adjustment and locking device, which can adjust the fine.

Since the collimating telescope optical system by abbe type and variable slit parallel light tube, lighting apparatus and dial, cursor, the collimating telescope is a reflection of the little green cross, when the telescope optical axis perpendicular to the reflecting surface, small cross in the reticle center of a certain position on the reticle, mobile eyepiece images can make the reticle.
