I removed the protective glass from a CMOS image sensor, and used optical immersion oil to couple the bare image sensor to a 40X NA=1.3 microscope objective.

ReplyDeleteHi Ben, I very much enjoyed your video on iron nitride magnets. I have been working with this technology for a while and have developed a method of producing large quantities of this material.
ReplyDeleteThere's still much more to check out, like few people working with it.
Would like to stay in touch.
