GSZ 2 - Greenough-Stereo-Zoom Microscope

Stereo-Zoom Microscope for Technics, Biology and Hobby

The GSZ 2 is a Stereo - Zoom Microscope after Greenough (Greenough type). There are two objectives, mounted together as a pair, with an 11° angle between them. Both eyes see the sample in a different angle, so that a stereoscopic effect, a three-dimensional image impression occurs.

The lenses are characterized by a high optical performance, a large flat field of view (field of view = 250) and a high depth of focus with a good chromatic aberration correction.

Equipment/Variants

The microscopes GSZ 2 can be configured individually with different stands, illuminations (reflected or transmitted light) based on halogen or LED, Photo-Adapter about the eyepiece cone, supplementary lenses, different positioning stages (e.g. for measurement tasks), polarization…

 

Dimensions W x D x H (mm): 320 x 320x 420

Dimensions GSZ 2 

 


The GSZ 2 is a versatile microscope, which because of its upright, laterally corrected images and stereoscopic observation is suited for all users, who wish to observe their objects in three dimensions with lower magnifications or to work/handle/manipulate under the microscope.

Photo adaptation for Eyepiece tube at the GSZ 2

The GSZ 2 microscope also offers the possibility of using an ordinary SLR or D-SLR camera for microphotography. To do that, the Photo adapter for the eyepiece cone is required and the corresponding T2-Adapter of the camera. The eyepiece has the function of a projective and comes from the standard equipment which is used.

- Photo adapter 3,2x for Eyepiece tube ø30/T2-thread   (305604:052.24)
  (for full format cameras 24x36mm) 

- Photo adapter 1,6x for Eyepiece tube ø30/T2-thread   (305604:127.24)
  (for APS-C cameras)

The articulated arm is used to attach the LED and halogen illuminations. The positioning of the illumination will be done by a simple alignment of the articulations and by clamping of the screws. The articulated arm and thus also the positioning of the illumination follows the movement of the drive in the height. The advantage of the articulated arm is the reproducible adjustment of the illumination angle of the illumination to the sample.

- Articulated arm for 3W-LED illuminator   (305442:032.24)

The dark field device provides optimal lighting conditions for samples which should be viewed in transmitted light with dark field contrast. Investigations of transparent and translucent objects are recommended by using the dark field device. Contours appear in clear contrast. Finest structures, streaks, surface damages can be seen better than in normal brightfield.

- Dark field device (304210:01022)
  (based on LED, an add. transformer 3W-LED (058544:510.26) is necessary or a Large stand with built-in power supply)

You can change the objective magnification very quickly with supplementary lenses. The lenses can be easily mounted in front of the microscope body or in the pivoting holder for attachment lenses (only used with the microscope body). The pivoting holder for attachment allows a fast exchange of the magnification range and is only available with the microscope body at a purchase.
