Easy, quick and simple upgrading of the Nikon Eclipse 55i and 50i microscopes for photography

With our LM digital adapters, Nikon’s two research microscopes Eclipse 55i and 50i (infinity-corrected) with Y-T TV tube can be equipped with modern DSLR and system cameras for high-quality photographic work in no time.

Nikon Eclipse 55i / 50i photo tube YT-TV

The Eclipse 55i and 50i are two laboratory microscopes from Nikon which are widely used in hospitals and research centres. Both microscopes are available with an ergo tube, which allows to set the viewing angle between 10 and 30 degrees. The binocular tube (C-TE Ergonomic Binocular Tube) with horizontal rear-facing camera port and C-mount unit (C-TEP DSC) has been designed specifically for cameras with 2/3-inch sensors. The C-TEP DSC port includes a built-in lens with a reduction factor of 0.7x, which cannot be removed. If cameras with larger sensors are attached to the DSC port, this will result in a loss of image quality. We therefore recommend using the trinocular eyepiece tubes Y-TF or Y-TT with Nikon Y-TV TV tubes (38 mm internal diameter) if you would like to attach cameras with larger sensors to these microscopes.

Fitting the microscope to digital single-lens reflex (DSLR), system or C-mount cameras is easy with our LM digital SLR adapters, which feature a plan achromatic optical system. Our products make it possible to capture top-quality microscope images. To help you select the adapter that is right for your camera, we have set up an online configurator on our website. You can also email us – ideally with attached photographs of your microscope.

Modern DSLR and system cameras offer the latest technology and are generally very well suited for microscopy applications. Most of them can be controlled remotely via PC/Mac. Because of their high sales volumes, they offer an excellent price/performance ratio compared to special-purpose microscope cameras.

Features of top DSLR and system cameras:
- Large, powerful full-frame sensors (36 x 24 mm)
- Sensor resolution of 50 megapixels
- High light sensitivity (ISO 100,000+)
- Extensive dynamic range (up to 14 aperture stops/f-stops)
- Short exposure times (1/8000 second):
- Full/Ultra HD (4k) video function
- Live video capture on external monitors in ultra HD quality

In most cases, these cameras are significantly more powerful than microscope cameras with smaller sensors (1/2" or 2/3"). On our website you will find our current camera recommendations and a camera ranking which is specifically tailored to microscopy applications.
