Schott Illuminators

It is the light that makes things visible. The aim of the application of light in stereo microscopy and stereo macroscopy is to increase the contrast of the observed object in order to emphasize those of its traits that are interesting to the viewer. In order to achieve optimal results, it is necessary to apply various illumination techniques.

EasyLED Series – Standard illumination for stereo microscopy

The EasyLED product line integrates advanced LED illumination with control functions in a single compact device. It is the ideal standard illumination system for routine inspections and education. Using the most current technologies, the EasyLED product line integrated high brightness LEDs with controller electronics into the head of the illuminator. This integration combines easy, ergonomic operation with outstanding price performance ratio.

Due to neutral white LEDs (5600K), images of excellent color fidelity can be achieved. Robust metal housings and well-designed heat sinks make maximum brightness and long lifetime of 50,000 hours possible.

EasyLED Ringlight Plus – Controllable in segments using the most current technologies, the EasyLED product line integrated high brightness LEDs with controller electronics into the head of the illuminator. The EasyLED Ringlight Plus lighthead is controllable in segments, which enables new contrasting methods.

The integrated “jog dial” wheel allows an easy and intuitive switching between the different illumination modes as well as rotation of the segments to both directions.

3. EasyLED Spotlights

Technical parameters:

  • High brightness power LED
  • Easy adaption at goosenecks, articulating arms and microscopes
  • Compact controller for continuous dimming  (0 – 100 %) and separate on/off switch
  • Total light flux: 40 lm

EasyLED Spotlight Plus It offers extremely high light output of 140 lm and therefore shines very bright. A heat dissipation device in the LED head ensures that the spot and thus the illuminated object always remain cool.

The EasyLED Spotlight Plus comes in two different versions: as an individual spotlight with a single lighting head and as a double spotlight with two lighting heads. The new Spotlight Plus’s LED head emits intensive light output of 140 lm. The light heads are equipped with special cooling lamellae that prevent the object that is being illuminated from heating up under the microscope. Furthermore, two LED heads can be used at the same time to achieve a sharp light-dark contrast in order to be able to view the objects under the microscope more clearly. The Spotlight Plus is also easy to use and ergonomical. With the double spotlight, you can even change between the two individual light heads by repeatedly pressing the on and off button. The appropriate mounts and adapters allow for the light to be mounted on different microscopes.

The EasyLED Spotlight Plus features a wide range power pack that covers a range of 100 to 240 V and 50 to 60 Hz. The individual and double Spotlight Plus have been officially tested and certified for use as laboratory equipment. They meet CE regulations and have thus been approved for the European market.
