LED illuminated stereomicroscope

Carl Zeiss has enhanced the performance of its Stemi DV4 stereomicroscope with an illumination system.

The DV4 on the C LED stand features integrated LED illumination units for reflected light, transmitted light and mixed light. The LEDs provide high light intensity with low power consumption and a long life (25,000 operating hours). To protect the specimen from heat, the light doesn’t contain infrared wavelengths.

Compared with the previous halogen illumination system, the stand offers brighter and more homogeneous illumination of the object field — with lower costs as power consumption has been halved.

The stand provides the benefits of the DV4, such as 4:1 zoom range, standard magnification range of 8x to 32x and a 92 mm working distance.

Attachment systems enable magnifications down to 5x or up to 64x and enhanced resolution.

Additional benefits include the out-of-the-box design featuring illumination in reflected/transmitted/mixed light and the possibility of flexibly upgrading the system with various accessories such as transmitted-light darkfield equipment or an eyepiece measuring device.
