  • Optical Touch Pointer for Fluorescence Guided
    Total tumor resection in. patients with glioblastoma multiforme (GBM) is difficult to. achieve due to the tumor's infiltrative way of growing and. morphological similarity to the surrounding functioning. brain tissue. The diagnosis is usually subjectively performed. using a surgical microscope
  • Near Field Imaging of a Laser Diode Using Scanning Method
    resolution was approximately 1 um. The measurement setup was constructed on Newport AutoAlign8000 alignment system, which consists of two motion stage stacks and a stationary center post. Beam profiling was achieved by using a high magnification microscope objective and scanning a detector with a pinhole
  • Understanding Spatial Filters
    removes this additional spatial noise from the system. The spatial filter assembly consists of a microscope objective, a pinhole aperture, and a positioning mechanism. The positioning mechanism has precision X-Y movements that center the pinhole at the focal point of the objective lens. Our TECH SPECTM
  • Fast Focus
    is much more subtle. The shape and position of the image projected on a bi-cell photosensor depends on where the optical system is with respect to its best-focus condition. When the microscope objective is too far from the substrate (left), the image resembles a half moon lying on the plussensor
