Questions & Answers
You are right. It should work. In addition to looking at spectra (and thus absorption lines) of neon and helium gas, I have also looked at various lasers and I am very pleased with the instrument for the price I paid. It is made in China and has inexpensive optics and adjustments, but I have found it to be quite good if you spend some time learning it and getting used to it. I am very thrilled with it for the price I paid.
There is a glass prism in place of the diffraction grating on this device.
The tool will work, but a more cost-effective and practical solution would be a small hand-held spectroscope
The visible light range consists of electromagnetic radiation that is visible to the human eye.
Selected User Reviews For American Educational 7-1928 Basic Spectrometer, 50A Spectrum Resolution, Includes Glass Prism
A bright and sharp spectrum is produced by this spectrometer, which seems to be of reasonable quality. It was not easy for me to see the sodium D doublet, so I believe the claim of 50A resolution stands. There are no coated lenses in the 16 mm optics (compared to the 32mm optics in Pasco student spectrometers). Metal parts are the majority, plastic parts are not so common, but they feel sturdy and solid. All joints are glued so there is no need for This was not an issue for me since the alignment of this one seemed to be right. In the visible spectrum, only the wavelength scale can be set, and after calibration (I did it with sodium lines), it appears to give reasonably accurate wavelengths. Despite attempts to remove reflections and stray light, there are still some visible in some parts of the spectrum that I could not remove. The views can be hindered by that.
It would have been nice if it had been more professional, but I wasn't ready to spend $300 on one. There are two main types of goniometers the cube and the bar An example of a light spectrometer would be The following are key points to remember An embedded scale is found in the third tube of those with three tubes It is possible to read the line frequency directly in the eyepiece This unit is of the first type (direct reading), it has a "protractor" on the base and the frequency is calculated based on the angle pointed at
This unit only has one tube. There is no need to calculate. I was not expecting such a high quality for this price, but I'm happy I've found it. . . . and now for the bad news Please note that. There is a great deal of plastic waste A fragile*brace yourself. The accuracy of the calibration is not very high (coarse settings, unknown calibration)* The screw mechanism is not working)*br It would be better if the optical quality were There is a visible deformation in one lens, but that does not affect the precision of the lens. Often, this is all you need (hey, sometimes it's all you want)-- The readings are decent in terms of quantitative analysis* - It is a useful device that has features such as a comparator and an The software is finicky, but it is I'm sorry -- This is a stable and sufficiently steady state* - In addition to being very easy to read, the scale is illuminated by a 3rd tube that allows it to adjust its brightness to correspond with that Please note that. This was a very sharp idea. Clearly defined and straight lines are used in this illustration. Essentially, what I am trying to say There is nothing fancy about this spectroscope that you can display in a science museum nor something that you can hand down to your grandkids, but if your main concern is education, it is definitely worth the money. My search for an entry level, educational spectroscope came up empty, so I decided to buy one. The unit I'm considering buying can probably be resold for the price I paid for it if I outgrow it, which won't happen, as long as I take great care of it. Teaching staff It is not a unit you want to leave in the hands of students (unless they are very disciplined) Easily abused. Won't stand up to even minor treatment. Make sure you conduct the experiment on your own and bring your pupils to the bench or use a webcam to see the inside of the room.
Because it is a low-cost model compared to those available on the market, I chose it. Since I was not expecting much from the performance, I was not disappointed. The real surprise came when I used the spectrometer to look through the collimator toward the simple light bulb that uses mercury gas as a fuel. I was very impressed with how bright the spectral lines were. It appears to be correctly aligned, which indicates that the collimator slit is accurate and the aperture adjustment screw is working smoothly. My jaw dropped when I saw what you did! have a "Project Star" spectrometer which uses a grating (the same model is available through Amazon) which I have always considered to have a good spectral show. It however shows fainter lines much better than the Basic Spectrometer. Mercury, for example, is very faint in the Project Star spectrometer, but it shows up really well in the Basic spectrometer. There is no need for adjustment in this model, as the prism comes already positioned. A light is placed in front of the third tube of this spectrometer to highlight very clearly the scale when a light is placed in front of it. It is easy to read because the scale has the unit of nanometers marked every 100 units with divisions between the units. In the 400 nm range, the division number has been doubled, so that the position of the spectral lines can be read with greater precision. In total, it measures 38 centimeters Wide from the tip of the collimator tube to the tip of the telescope tube. Compared to the latter, the scale tube is shorter. In order to be able to fully view every part of the spectrum, the telescope swivels for a short arc, and has a handwheel to handle the rotation. The eyepiece of the telescope needs to be moved back and forth in the telescope until there are no blurring lines. In addition to the collimator, there is a small prism and mirror attached for "illuminating the lower half part of the slit. ". In order to adjust a manual slit widener, simply slide it to the desired position. There are two adjustments to be made Comes with two eyepieces for low and high magnification. Slit width is adjustable by a screw and height is adjusted by a manual slide just beside. There are three pages of instructions with suggestions for experiments. The instructions are fairly detailed and easy to read. Specifications of the lens (type and focal length) are stated in the instructions, as well as a directory of parts and uses of the instrument. Although I haven't tried the small prism and mirror in front of the collimator, I can imagine that they work accurately and are well made, but I cannot say for certain how they work. A flint glass prism is used as the main part of the instrument A major benefit of this type of telescope is the ability to view The last thing I would like to say is that I think this wonderful instrument would be ideal for a young person who has not yet used a standard design "G&T" In school, students are expected to follow a model of the type "G". I would recommend this book to high school students, as mentioned in the add. It would also be a good book for a person like me who is attracted to the beauty of light and the basic elements in a not too scholarly way.
It could've been a great value, but it was glued in place and not aligned properly for every part that should've been adjustable. It was not possible to adjust the slit assembly to its correct vertical position as it was glued into place with about a 10 degree angle and the slit assembly had some rust on it.
I got it as a complement to my work with chromatography. I like it very much, but one has to be aware that having an optical bench is necessary. Also, I use a CCD camera with my computer for capture, and focusing may be a bit of an issue, but it can be overcome. The price was well worth it.
This is the kind of music I like. I like the way it works!.
