Trinocular stereomicroscope with 7-63x zoom for observation and photography

The Science ETD-301 stereomicroscope is a stereo magnifier with high-quality optics, designed for 3D observation with photo/video documentation. Sound 0.7x to 6.3x zoom lens (9x zoom) allows continuous magnification from 7x to 63x, combined with a long working distance of approx. 100 mm to work comfortably around the sample.

It is suitable for a wide range of applications, including medicine, agriculture and forestry, forensics, research and teaching, as well as the assembly and testing of small parts in precision mechanics and electronics.

Powerful zoom and precise focus settings

The 9x zoom offers great flexibility in moving from overview to detailed observation. The stand incorporates a coarse and fine focusing, This is particularly useful at high magnification and in photography, to obtain precise, stable sharpness settings.

Rotating trinocular head and optimized optical path for the camera

The trinocular head can be rotated to 360° and features two eye tubes inclined at 45° for comfortable viewing. The trinocular output allows camera connection via adapters, including :

  • SLR and hybrid cameras (via mount) T2 with camera-specific T2 ring),
  • mount cameras C (up to sensor 1″ depending on adapter/camera).

A switch can be used to divert the beam from an eyepiece to the camera, putting the camera in the right position. 50% of light available for shooting, which can be advantageous compared to permanent beam sharing.

Incident and transmitted LED lighting, continuously adjustable

The microscope features LED incident light and lighting Transmitted-light LEDs. The two lights can be used separately or simultaneously, and are continuously adjustable via dimmer to adapt brightness precisely to the sample and observation method.

Wide base and work space for bulky objects

The wide base with turntable makes it easy to observe larger objects. The maximum object height is approx. 85 mm. The large working distance also makes it possible to use tools for tasks such as preparation, dissection, measurement or inspection.
