The SM745NTP is a 7X-45X continuous-zoom trinocular stereo microscope head with a simul-focal photo port. The simul-focal port allows the use of a camera while simultaneously using both eyepieces. This is ideal for systems that require a constant video feed or frequent snapshots. The photo port can be adjusted to help ensure that the camera and eyepieces are all properly focused. With our unmatched lineup of cameras, a wide range of solutions are available, including HDMI video, computer-based imaging and measurements, time-lapse capture, and wi-fi or LAN networking.
The microscope’s high-quality optics produce stunning contrast and accurate colors with a viewing area of up to 28.6mm. The 6.4:1 parfocal zoom range provides magnifications up to 45X while maintaining a 4" (100mm) working distance. A new zoom-lock feature can be used to maintain constant magnification while performing measurements.
Interchangeable eyepieces and auxiliary lenses can increase the magnification up to 225X. Rotating interpupillary adjusters provide a custom fit for each user. The included eyepieces have integrated diopters to ensure sharp focus for users with certain vision impairments. Comfort is further enhanced by the 45° viewing angle, as well as high-eyepoint eyepieces which accommodate glasses and goggles.
The SM745NTP is designed to be mounted to 76mm collars. It can be used with a wide range of stands, including our SAW, DAW, and BBB boom-stands, as well as various table stands and articulating arms.
