Description

A collimator slit device

technical field

The utility model belongs to the field of physical experiment instruments, and relates to an optical experiment instrument component, in particular to a parallel light pipe slit device.

Background technique

A spectrometer is a commonly used optical experimental instrument. A spectrometer is composed of a collimator, a telescope, a stage, etc., and the collimator is used to generate parallel light. One end of the collimator is the objective lens, and the other end is a slit device with adjustable width. When the slit device is actually used, due to frequent adjustments by students and improper force, the slit adjustment handwheel will often fail and the slit width can no longer be adjusted, resulting in the slit being too wide, too narrow or even completely closed. Therefore, the experiment cannot be continued.

Contents of the invention

The purpose of the utility model is to develop a collimator slit device which is not easy to be damaged, and is convenient to adjust and use.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A collimator slit device, comprising a slit box, a slit plate and a sleeve;

The slit box is in the shape of a hollow disc, and the front of the slit box is provided with a long slit window along the diameter direction of the slit box, and a parameter window for displaying the slit width parameter is provided directly below the slit window, and the side wall of the slit box A slit plate slot is arranged across the side wall on the circumference;

The sleeve is a hollow cylinder, and the sleeve is coaxially connected with the slit box. The joint is located in the middle of the back of the slit box, and the sleeve is inserted into the collimator of the spectrometer;

The slit plate is rectangular, and the slit plate is movably inserted into the slot of the slit plate. There are linear light-transmitting slits on the slit plate along the width direction of the slit plate. The slit plate below the light-transmitting slit is marked with Gap width parameter.

The number of the light-transmitting slits is at least three, and the slit-width parameters of each light-transmitting slit are different.

The beneficial effect of the utility model is: by moving the slit plate, the slit of required width can be moved into the slit window for experimentation, and the corresponding slit width parameter can be read through the parameter window. The device is easy to operate, durable, does not produce mechanical failure, and brings convenience to the adjustment and use of the collimator.
