TILL Photonics (Victor, NY) has announced its dual-color, 2-photon imaging fluorescence microscope, IntraVital2P. The IntraVital2P facilitates imaging at low-light levels and improves SNRs for dynamic measurements deep within highly scattering tissue. Using TILL’s Yanus IV digital scanhead and voice coilbased z focus drive, the IntraVital2P scans large areas (up to 22mm field diagonal) and acquires 3D images with reduced phototoxic effects. The microscope combines excursions of up to 7.5mm with 50nm resolution and a step response time of <10ms. Other features include a 25× objective, NA 1.1, < 1μs pixel dwell time, and digital galvo control.
