BACKGROUND:The Confocal Imaging Facility (CIF) of the National Institute on Aging IRP has a VT-iSIM microscope with a relatively limited field of view (FOV). This upgrade will increase the FOV at 100x objective 2.7-fold, a significant improvement. This larger FOV will have a broadband and homogenous illumination (Flatfield).These improvements will allow the CIF to maintain a state-of-the-art SIM superresolution system, so that NIA IRP core users will obtain the highest-quality SIM super-resolution images.NIA investigators will be able to continue implementing a broad range of experimental projects essential to the core mission of the NIA. The Visitech VT-iSIM has unique properties not offered by any other vendor.PURPOSE AND OBJECTIVES:Visitech VT-iSIM Flat Top & Full Field upgrade to super-resolution microscope are essential for increasing camera FOV and adding capabilities to the VT-iSIM that will enhance the imaging and sensitivity of this system so it will remain in the forefront of imaging research at the CIF of the NIA IRP.GENERAL REQUIREMENTS:
