Furrow on a Glass

80-100 Angstrom furrow in glass? diamond tip or laser

Whatever it does not matter the important is the dimension

Is the finish important? you could make a thin line with a diamond scriber. If you can get a 'V' shaped groove cut by grinding or other machining & it is too wide, you could polish back the surface of the glass to make the groove thinner.

I have to make several furrows across a concrete piece of glass

Athmio,

Precitech builds machines for the optics industry. Their sales or applications people may help you find an optics shop for the job. www.precitech.com

Thank you

Find a local window manufacturer many have or know some one that can furrow the glass for you.

Hi athmio. What are you making, a diffraction grating for a spectrometer? Spencer.

Try etching a furrow. This can be done with great precision. There are several chemicals that can be used and you can vary the concentration to get an etch rate which you can control. A mask may be required.

What depth do you need?

There are several methods that could be used, but it depends on your application which would work best with the project.

- grind v-notch and polish down

- etch

- patterned thin film coating on glass (me preferred method)

Hi IRDglass. I agree with you. I built my own optical spectrometer using this method. I bought a plastic film of optical grating from a Japanese firm many years ago, then I glued it to a sheet of thin glass. This still works well, and I think that the guy should contact a Japanese optical company. Spencer.
