Abstract
The utility model relates to a laser geometric optics demonstration instrument, belonging to the teaching appliance, composed of a graduated disk, a reflecting mirror, a water tank, a bracket, a laser, an adjusting mechanism, a switch, and set screws. The laser is installed on the graduated disk that is slotted and installed on the bracket, the set screws and the water tank are arranged on the bracket, the reflecting mirror is attached on the water tank, and the upper of the laser is provided with the switch and the adjusting mechanism. The laser geometric optics demonstration instrument adopts a he-ne laser that has a long light source, only three pieces of electric cells are required for using the he-ne laser, the he-ne laser can output fine beams with convenient maintenance and is free from the limitation of classroom power facilities, and merely the light source part can save money and reduce cost.
Description
The utility model relates to a kind of laser geometric optical demonstration instrument of instruments used for education.
Existing laser optical demonstration instrument, the light source volume is big, and power supply adopts to exchange and is converted to direct current output.The instrument of this power supply only is suitable for the school that campus facilities is good, there is power supply in the classroom, economic condition is good and is equipped with.And laser instrument is fragile, and after light source damaged, whole instrument can not use, and causes the significant wastage of school eduaction fund.Former laser optical demonstration instrument can not be demonstrated light and incide liquid from air, light generation refraction effect.
The purpose of this utility model is exactly the generation for fear of above-mentioned situation, and a kind of employing helium-neon laser is provided, and uses the laser geometric optical demonstration instrument that is not subjected to classroom power supply facility restriction.
The utility model laser geometric optical demonstration instrument it by: index dial, catoptron, tank, support, laser instrument, adjusting mechanism, switch, jackscrew are formed.Laser instrument is installed on the index dial, and index dial has groove and rack-mount, is equipped with jackscrew and tank on the support, and catoptron is attached on the tank.Be equipped with switch and adjusting mechanism on the laser instrument, adjusting mechanism by: slide block, spring, push rod, adjustment nut are formed.Slide block is positioned in the index dial groove, is connected with laser instrument.Push rod is positioned in the slide block center pit and is connected with the adjustment nut, adjusts nut and is installed on the slide block.
The utility model laser geometric optical demonstration instrument, adopt helium-neon laser, light source is long, and only needing to install 3 batteries can use, output beam is thin, easy to maintenance, use not limited by classroom power supply facility, singly be that the Lights section has just been saved fund greatly, reduced cost, it can be closely in conjunction with junior physics teaching material reflection of light, and imparting knowledge to students in the refraction knowledge point of light, has given prominence to the emphasis and the difficult point of teaching material.
