Nikon Diaphot TMD Inverted Microscope

The Nikon Diaphot TMD is a research-grade inverted microscope originally introduced in 1980 as an evolution of the Diaphot MD. Built for advanced biological and biomedical applications, it delivers high-performance imaging for live-cell observation, fluorescence studies, and precision photomicrography. With its reinforced design, versatile optics, and adaptability for specialized techniques, the Diaphot TMD remains a trusted tool for laboratories focused on cell culture and advanced imaging.

At HiTechTrader, we restore and supply Nikon Diaphot TMD microscopes that have been fully serviced, calibrated, and tested to meet demanding research standards. Our refurbished units provide the same optical clarity and mechanical precision as new systems, at a fraction of the cost, making them an excellent choice for laboratories seeking reliable, high-value imaging solutions without compromising performance.

General Description

1. Optimized for low-light photomicrography and live-cell imaging

3. Accepts CF objectives (chromatic aberration corrected) for accurate color reproduction
4. Reinforced stand with low center of gravity for stable imaging performance

Optical and Mechanical Features

1. Supports brightfield, phase contrast, fluorescence, DIC, and Hoffman Modulation Contrast (HMC)
2. Extra-long working distance condensers with high NA for phase contrast and HMC
3. Stage options include: 
1. Plain fixed stage
2. Precision mechanical XY stage for scanning
3. Specialized stages for microplate handling and automation
4. Binocular head inclined at 45° with adjustable interpupillary distance and diopter
5. Built-in focusable Bertrand lens for phase ring alignment
6. Integrated dark slide for light routing between eyepiece and camera ports
7. Smooth coarse and fine focus with adjustable torque control

Illumination System

1. Standard 50W halogen lamp for brightfield and phase contrast
2. Optional 100W mercury lamp for fluorescence imaging
3. Built-in power supply with brightness adjustment
4. Multiple filter holders for heat absorbing, ND, color correction, and diffusion filters
5. Accepts fluorescence filter cubes for both UV and visible light excitation
