Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The invention is a device for comparing the refractive index of optical glass, comprising a fixed base 1, a glass clamping frame 2 is connected to the fixed base 1, a scale plate 3 is fixed directly below one end of the fixed base 1, and the scale plate 3 is close to the fixed base 1. The other end of the glass clamping frame 2 is connected with a clamping frame 4, and the laser pointer 5 is clamped in the clamping frame 4.

[0017] The light emitting wavelength of the laser pointer 5 is 650nm-670nm.

[0018] The size of the scale plate 3 is not less than 30cm×30cm.

[0019] The minimum scale value on the scale plate 3 is 1 mm.

[0020] The clamping frame 4 is a support for adjusting up and down.

[0021] When using a device for roughly comparing the refractive index of glass in the present invention, place the regular cuboid glass to
