500 Lines Handheld Spectroscope

Mainly used to observe and analyze the spectrum of light. Analyze the spectrum of a luminous body: By analyzing the spectrum of light emitted by different light sources (such as the sun, lamps or lasers), Users can learn what different colors in the spectrum represent and infer the composition of the light source. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_b7b8d162-9560-4fe8-9a7d-7e67eaea446d.jpg What is a beam splitter? A beam splitter is a tool that separates light! White light (such as sunlight) is actually made up of many colors of light, such as red, orange, yellow, green, blue, Indigo, and violet. When white light passes through a beam splitter, these different colors of light will be separated like a rainbow and arranged in order! 👉 Why can they be separated? Because each color of light has a different "wavelength", and the spectroscope can distinguish the two according to the differences in these wavelengths. Break them apart to see the full colors! https://www.giataiwan.com.tw/sysedit/App_Upload/JewelNews/U_16432.jpg Just point it at different light sources and see which wavelengths are present! Different wavelengths of light make us perceive different colors, red has the longest wavelength and violet has the shortest wavelength. Light enters through the slits and is decomposed by the grating at the other end, presenting a beautiful spectrum effect. Once a fixed slit is mounted on one end and a diffraction grating is mounted on the other end, These components can be used to check incandescent and fluorescent lamps, flame tests and filters. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_e3ef8492-3bcf-46bd-80b8-dff0a6ff3ca1.jpg Using the principle of light dispersion, composite light is decomposed into its constituent wavelengths (colors). Forming a continuous spectrum or a line spectrum. Continuous spectrum: Light emitted by, for example, an incandescent lamp, which appears as a continuous band of colors like a rainbow. Absorption spectrum: When light passes through a gas or liquid, certain wavelengths of light are absorbed and dark lines appear in the spectrum. Emission spectrum: For example, neon lamp and hydrogen lamp show bright lines of specific wavelengths, representing the characteristics of the element. https://m.media-amazon.com/images/I/61aHbuvdhFL._SL1500_.jpg The 500 Lines refers to the line density of the grating, that is, 500 dividing lines per millimeter, which is the core component of the spectroscope. When light passes through a grating, according to the law of diffraction, the light waves are separated into different wavelengths, forming a spectrum. The higher the line density, the stronger the spectroscopic ability, so the spectrum of the light source can be accurately analyzed. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_a0c9f1ae-6318-403a-b9e3-6f37578ddb66.png What is the principle of spectroscope? Beamsplitter structures can generally be divided into two categories: cubic or flat Can reflect or transmit light. The main adhesive components of the beam splitter are polyester, polyurethane or epoxy resin. Using different components will also cause different reactions to the incident light. Light passes through adhesives of different thicknesses, allowing half of the light beam to be reflected and the other half to be transmitted, dividing the original beam of light into two separate beams according to the designed proportions. In addition to splitting light, a beamsplitter can also operate in reverse, combining two separate beams into one. Directions: 1. Transmitted light method Suitable for translucent to transparent, larger Gemstone to ensure that enough light can penetrate the Gemstone and enter the spectroscope. (1) Place the sample to be tested directly on the spotlight. If the sample is too small, a light baffle should be used. Place the sample over the appropriate hole in the light baffle to block out excess light. (2) Hold the beam splitter in your right hand and align the slit with the light passing through the sample. Observe the spectrum through the eyepiece and adjust the position of the spectroscope until the spectral lines are clearest. 2. Internal reflection method Suitable for transparent Gemstone with lighter colors and smaller Gemstone particles. (1) Place the sample to be tested face down on a black background. (2) Hold the light source (such as a focusing flashlight) in your left hand and shine it obliquely on the sample. Hold the spectroscope in your right hand. Align the slit with the light reflected from the sample and observe the spectrum through the eyepiece. At the same time, adjust the position of the spectrometer until the spectrum is clearest. 3. Surface reflection light method Suitable for Gemstone with poor transparency. The observation method is the same as the internal reflection method. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_dca986c9-18a7-4572-92d2-a4f7dbdc1fd9.png https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_589816f8-a875-40ec-9333-de25d96842ca.jpg https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_59f9d465-0f5b-463e-a66c-7bacea87997c.jpg Product Specifications: ► Body diameter: 1 inch/2.54 cm ► Diameter at both ends: 1.15 inches/2.921 cm ► Grating density: 500 lines/mm ► Spectrometer length: 10.25 inches Notes: ► Keep away from fire
