40X-1000X Trinocular Inverted Biological Microscope With Phase-contrast

The IN300T provides high-resolution optics & an inverted illumination system in a stable, ergonomic design for observing cell cultures & other biological & chemical specimens in brightfield & phase-contrast. The inverted form accommodates larger specimen containers, with multiple specimen templates & mechanical stage controls to improve workflow. High-resolution optics & phase-contrast capability maximize contrast & clarity to ensure high quality images.

The viewing head has a 45&deg incline & Siedentopf interpupillary adjustment for flexibility & comfort. Super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. For users with astigmatism or asymmetrical vision, the right ocular can be adjusted to fine-tune focus. The trinocular format provides a dedicated photo-port for mounting a microscopy camera for capturing photos or videos. The 23mm photo port is height-adjustable to match focus with the eyepieces.

The 10X & 20X objective lenses are equipped with phase rings for phase-contrast observation. By sliding the provided phase-annulus board into the overhead lamp, the transmitted lighting is quickly changed to work with the objective lenses to enhance contrast in hard-to-see samples such as live cells which cannot be stained. By manipulating variances in phase caused by changing refractive indices, once imperceptible details can present as transitions from dark to light.
