Microscopy lab providers by MicroVision Laboratories, Inc.? Translucent or transparent coatings on metallic or semi-conductor substrates are very difficult to image due to their reflective nature. Nomarski/DIC imaging is an effective method for accentuating differences in thickness, density or the optical index in these cases. This analysis enhances and highlights subtle features with brilliant color gradients and captures them with a high resolution digital imaging system. Let us bring out your sample’s hidden features.
Approach: MicroVision Labs’ staff consulted with the client, and determined that, unfortunately, there could be a number of potential sources of a white material. Even before the bottle with the suspended material arrived, it was determined that there was less than 50 mL of water remaining, and likely less than a gram of material suspended in the water. The client was aware that this material could represent precipitated minerals from the source water, a polymer residue from the bottles, some form of biological tissue that might have formed despite sterilization procedures, or could very well represent some completely unforeseen foreign material. The issue facing the client is how to have the material tested, as most tests that they might request for one or the other of these known potential sources would destroy or alter the sample. Choosing a test was therefore something of a gamble, because if they tested for calcium (mineral precipitate) and it came up negative – that didn’t actually tell them what the powder was, just that it didn’t have any calcium. Based on this conversation, the non-destructive, specialized testing at MicroVision Laboratories was chosen as the best choice.
The profile of the flow of the solder at these bonds was documented using the SEM with backscatter imaging, which correlates brightness in the image with atomic density. Some voids were found in the solder as shown the SEM image. An EDS spectrum of the solder was acquired which showed that the solder was a tin/lead (80/20) solder. The EDS map clearly shows the copper wire and copper pad (red) with the tin lead solder (light blue) that appears to have flowed well and made a good bond between the copper elements. This map also shows the fiberglass bundles that add structural integrity to the board.
What if I want a service not listed in your services list? At MicroVision Labs the list of services which we provide to our clients is constantly growing. So if you don’t see what you are looking for give us a call or use the Contact Us tab. Also don’t forget to check our Additional Services Page to see if it might be listed there. Can you identify a contamination or unknown for us? Yes, we call that an Unknown Material ID and we routinely work on that kind of project. We have a number of individual tests designed to classify unknown materials. When combined with our extensive suite of equipment, these tests allow us to identify virtually any material. Give us a call and talk to one of our knowledgeable staff for more information. See even more details at https://microvisionlabs.com/imaging-technology/.
The client was able to determine the source of the black dust was due to the mechanical breakdown of the foam cushions in the impacted room, and not from mold or mildew growth. The experienced analysts at MicroVision Labs were able to differentiate the foam materials from either blown cellulose or urethane foam insulation or air filters, allowing for the client to easily remove the problem cushions.
