SUMMARY

This discussion focuses on the challenges of removing Bayer filters from CCD sensors for the purpose of creating monochrome cameras suitable for UV photography. Users have reported damaging CCDs during the removal process, with one individual experiencing failure due to short circuits and pixel damage. Chemical methods, such as using acetone, have proven ineffective, leading to suggestions for alternative solvents like methyl ethyl ketone (MEK) and methylene chloride. The conversation emphasizes the need for proper tools and techniques, potentially involving assistance from chemistry professionals.

PREREQUISITES
  • Understanding of CCD sensor technology
  • Familiarity with Bayer filter functionality
  • Knowledge of chemical solvents and their applications
  • Basic skills in handling delicate electronic components
NEXT STEPS
  • Research the chemical properties and safety protocols for using methyl ethyl ketone (MEK) and methylene chloride
  • Explore methods for safely removing Bayer filters from CCD sensors
  • Investigate the availability of monochrome CCD sensors for UV photography
  • Learn about the role of microlenses in CCD performance and how they interact with Bayer filters
USEFUL FOR

This discussion is beneficial for electronics hobbyists, photographers interested in UV imaging, and anyone involved in modifying CCD sensors for specialized applications.

Hello, I want to make B&W camera, for UV photography. I already destroyed two ccd's by trying to remove it. First stopped working after tiny golden wires were damaged. About second ccd I don't know. When I putted it into smartphone, in camera mode it showed black image. It seems that I didn't cut wires, but just short circuited with another or maybe I damaged pixels with screwdriver. I'll check latter
Problem is that it is impossible to remove bayers filter chemically(I used acetone), only by using something sharp. When I rubbed ccd with cotton and acetone, first I got matted surface and later red, I couldn't go further I know that acetone is powerful organic solvent, so is it possible that dyes are inorganic?

Fresh ccd, that thing on surface is not wire.

No suggestions?

This looks like a very interesting project and I have no suggestions for you other than perhaps post this in the astronomy board. Monochromatic CCDs appear to be common in that field.
 
I'm afraid you won't have any choice but to use a chemical or vapor strip process. The tools involved in grinding over the surface of a die are extremely fine, and you won't be able to replicate this with a knife.

If your in college, I suggest going by the chemistry department and attempting to get help from a grad student or prof.

They have the proper chemicals, tools, and means of disposal to make short work of your project.

The trick is to find the proper solvent / reagent. I've had ok luck with with methyle-ethyle-ketone (MEK) and great luck with methylene chloride when disolving stubborn polymers. Just be sure to use it in the lab with the proper support. It's bad stuff to use without a hood. Also, watch out that you don't eat your packaging.

I bought used JVC camcorder and will try to find out if CCD module can be manufactured that already would be monochrome, without risk and loosing microlens.
 
Also impossible to remove on JVC camcorder rubbing with acetone and scrapping with blade, but on older camcorder I easily removed it. Maybe that sensor has glass plate on top of CFA?
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
