3B Scientific U21877 Spectroscope in Metal Case

The reason I chose this spectroscope was that it had a wavelength scale and the build looked more sturdy than any other educational teaching spectroscope. As soon as I got home, I checked the fluorescent light spectrum for the first time. The spectrum has a lot of bright lines of mercury all over it. The most prominent Hg line at 546 nm has been found to be quite distant from its correct position by at least 20 nm. We returned the first spectroscope and replaced it with a new one. It turned out that the new product has the same defect as the defective one. The manufacturer has been notified of the I am disappointed to discover that it can not accurately estimate wavelengths. The apparent quality is excellent, but the scale is just too inaccurate for me.

Here are a few up-to-date links A disclaimer at the front In the following, I compare these devices from the perspective of a geek, not someone who is relying on them for a specific purpose (e. g. This is the identification of gems). In a spectrometer The production of a spectrum which reveals the relative colors in a light beam is known as a spectrometer. A spectroscope that features a graduated scale that allows people to measure the frequency or wavelength of the components of color.
The majority of the things I own fall under this definition. There are no high-end items in my collection Laboratory spectrometers (the devices with a separate collimator/slit tube, a rotating table holding a prism or diffraction grating, a rotating telescope for viewing, and protractor scales for the prism positions and telescope positions). Besides diffraction gratings, the other four models are also based on them. Two are simple spectroscopes, two are spectrometers, and three are both at the same time.
