  • 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
  • Utilizing Aspheres in Optical Design
    Improving image quality, reducing the number of elements needed and lowering costs are all now achievable through the use of aspheres in optical design. From digital cameras and CD players to high-end microscope objectives and fluorescence microscopy, aspheres are proliferating into every facet
  • 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
  • Precision moves with pint-sized motors
    Innovative actuators and stages based on piezoelectric materials give superfine motion in a compact package. A typical use for PZT actuators is in the precision positioning of microscope objectives. The MIPOS 500 stage (top) from Piezosystem Jena Inc. is one example of a device designed
  • Medical Device Link .
    , TN 38502. A company offers two lines of video microscopes designed for video inspection in product manufacturing. The VM-40 and -60 Measurescopes use a newly designed video measuring head mounted on a microscope stand made of cast steel for excellent manual video inspection capability. Both models
