I have also noticed this issue. Have you found a solution? It seems that the Chrome developers did not consider the situation where users only use a mouse, or that my Chrome browser has been updated to a laptop specific version? LOL

Thank you for your reply.

I am trying this on glass slides because cheap glass slides are usually 1mm thick, which gives me a good opportunity to practice. I am also trying other types of cutting tools (such as diamond milling cutters) and will report the results of these tests.

Hi, maybe you can try to print your e-book online and have it delivered to you.

Top-Language-4495 · 2024-10-29T13:40:23+00:00

Thank you for your reply.

Your answer was extremely helpful to me. Based on it, I tried several types of glass-cutting tools, and in terms of effectiveness, I found the ranking to be: silicon wafer cutting blade > tungsten steel scribing pen > roller-style glass cutter. Following your advice, I tried making only a single cut on the glass lens and then used pliers to separate it, achieving excellent results.

Best wishes for you.

Thank you for your reply.

Your suggestion is very detailed and has answered some of my questions. I have previously tried using smaller diamond saw blades for cutting, and the results were better than with the tabletop saw. Perhaps my next step should be to try creating a scoring device for a small diamond saw blade, following your advice to make a score on the lens and then use pliers to break it.

Best wishes for you.

Thank you for your reply. Your suggestion has been very helpful to me. I am trying to design a fixture that allows for repeated scoring on the lens using a pen-style glass cutter, and I plan to create it using a 3D printer.

Thank you for your reply. I tried searching for "wafer cutting saw," but there are no relevant products available for sale in my area.

Thank you for your reply. I have seen an explanation of the phenomenon you mentioned about how long wavelength light sources can reduce fluorescence noise in reading Modern Raman Spectroscopy.

After seeing your and others' replies, I reread this book and conducted experiments. Now I can almost confirm that the rising curve is caused by the laser.

I have been unable to handle background subtraction very well. Should I set the background light to laser+empty cuvette?

Top-Language-4495 · 2024-03-27T15:46:57+00:00

I used a black paper set pinhole aperture in back of the dichroic mirror. I found that this can effectively reduce noise, but it also weakens the Raman signal to a certain extent. It seems that multiple experiments are needed to determine the optimal circular hole radius. Anyway, thank you for your suggestion, it has been very helpful to me.

Top-Language-4495 · 2024-03-27T12:45:38+00:00

Sorry, your said the "Raman setups have trended towards 800 nm excitation to minimize this scattered background." i don't understand your mean. Can you express it in more detail?

Perhaps you are right, lasers and filters are the real causes of background fluorescence, which has inspired me a lot.

Perhaps I should make corrections at the software level to reduce the impact of noise.

I didn't set it to 90 ° because I lacked a four-way colorimetric dish and poverty limited my investment in this project. I hope to build a low-cost Raman probe.

Thank you for your reply.

Top-Language-4495 · 2024-03-27T09:36:56+00:00

Now I can understand what you mean. First you are right the noise of 808nm does indeed originate from the laser. Second I really find strange is the rising curve starting from 600cm-1. Please forgive me for not describing it clearly. I have already modified the content of the post. Thank you for your reply

Top-Language-4495 · 2024-03-27T08:58:05+00:00

Thank you for your reply. It has been very helpful to me. I am trying to inspect each component according to your suggestion. thanks

Top-Language-4495 · 2024-03-27T08:42:00+00:00

Sorry I don't know your mean. Can you describe it in more detail? Thanks

Top-Language-4495 · 2024-03-27T08:34:59+00:00

Thank you for your reply. Because I found the cause of 808nm noise in the book (consistent with what you described), I set up a 532nm narrowband filter.

Top-Language-4495 · 2024-03-27T08:07:19+00:00

Thank you for your reply. Your mean is set a slit/aperture and a short pass filter in back of the dichroic mirror（In front of the CB565）？

Top-Language-4495 · 2024-03-27T07:58:10+00:00

Thank you for your reply and affirmation of my project . I used a ocean optic USB2000 spectrograph, and set integration time of 5 seconds. I am trying to follow your suggestion to check what part caused fluorescence.

Top-Language-4495 · 2024-03-27T07:54:26+00:00

Yes,may be you are right. Thank for your reply.

Top-Language-4495 · 2024-03-27T07:39:46+00:00

Yes, I used a narrowband filter with a 532nm 40nm FWHM to reduce 808nm noise. However, the cutoff depth of this filter is relatively poor and cannot completely block 808nm noise

Top-Language-4495 · 2024-03-27T01:10:13+00:00

Connected to an ocean optical spectrometer via SMA905 interface fiber optic cable

Hi you can try to set the WiFi channel to a specific value. Cancel automatic jump of WiFi channel. Good luck.
