{"product_id":"spectrometer-student-each","title":"Spectrometer, Student (Each)","description":"0 to 360 degree rotation, 1 degree graduations, and a 0.1 degree vernier scale to provide hands-on experience observing and measuring light spectra. The collimator is mounted on a spring-loaded support, integral with the base. The collimator tube has an adjustable slit on one end and an achromatic converging lens with a 178mm focal length on the other end. The lens is secured in a tube that can be hand adjusted to ensure the slit is in the focal plane of the lens to produce parallel rays. The collimator scale has a 170mm diameter and 0 to 360 degree rotation at 1 degree intervals. It is capable of independent rotation and has a locking screw. \u003cbr\u003e\u003cbr\u003eThe prism table is mounted on a 175mm diameter circular degree scale. The scale is rotatable around the central axis and is provided with a clamping screw. The prism table has three leveling screws and marked lines to assist with precise placement of the prism (sold separately). \u003cbr\u003e\u003cbr\u003eThe astronomical-type telescope is mounted on heavy bearings, and can be rotated around the central axis of the apparatus. It consists of an achromatic objective at one end, and a Ramsden eyepiece with crosswires at the other end. The position of the lens can be hand adjusted. A clamping screw allows the position of the telescope to be fixed, and a tangent screw provides fine adjustment. A vernier scale allows the position of the telescope to be read to a precision of 0.1 degrees. \u003cbr\u003e\u003cbr\u003eThe body and structural parts of the spectrometer are comprised of heavy castings to provide precision and durability. The spectrometer weighs 10.9 lb. and is 11 x 12.2 x 16.5 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back).\u003cbr\u003e\u003cbr\u003eIncludes:\u003cbr\u003e- Eisco PH0619 spectrometer\u003cbr\u003e- Prism clamp\u003cbr\u003e- Diffraction grating holder\u003cbr\u003e- Screwdriver\u003cbr\u003e- Tommy bar\u003cbr\u003e- Storage box\u003cbr\u003e- Instructions","brand":"EDULAB","offers":[{"title":"Default Title","offer_id":42700494635069,"sku":"107K00671","price":2188.2,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/2583\/0205\/files\/VTN12302458-1.jpg?v=1762706251","url":"https:\/\/eduplaninternational.com\/products\/spectrometer-student-each","provider":"Eduplan International","version":"1.0","type":"link"}
