Numerical Aperture and Resolution. The numerical aperture of a microscope objective is a measure of its ability to gather light and resolve fine specimen detail at a fixed object distance. Image-forming light waves pass through the specimen and enter the objective in an inverted cone as illustrated in Figure 1.
Nolvadex (tamoxifen citrate) is a nonsteroidal antiestrogen used to treat breast cancer that has spread to other parts of the body (metastatic breast cancer), to treat breast cancer in certain patients after surgery and radiation therapy, and to reduce the chances of breast cancer in high-risk patients.OLVADEX (tamoxifen citrate) is well tolerated in males with breast cancer.
