SCHOTT EasyLED
Ergonomic Illumination for Stereo Microscopy
The EasyLED series is an innovative illumination system specially designed for 
stereo microscopy.
Employing the newest technologies, SCHOTT has integrated high brightness 
LEDs and controller electronics into the head of the illuminators. 
This saves space on the workbench and allows easy and ergonomic operation, 
directly on the microscope. There is no need to remove eyes from the eyepi-
eces to find a controller box somewhere on the bench.
Continuous dimming and a separate on/off switch keep the settings 
unchanged for the next day’s session.
EasyLEDs DC-driven light is neutral white (approx. 5,600K) and absolutely 
flickerfree. It generates images of excellent color fidelity and is well-suited for 
use with digital cameras.
All illuminators come with wide range power supplies (100 – 240 V) and 
international clip-in plug adaptors, ready to use all over the world.
Robust, black anodized metal housings and well-designed heat management, 
afford outstanding brightness and lifetimes of 30,000 hrs.
Due to the fanless design, EasyLEDs are quiet, free of vibration and can be 
used in cleanrooms as well as rough environments.

Savings on halogen bulbs, clearly re-
duced energy, service and downtime 
costs, make EasyLEDs a very attractive 
choice compared to halogen light  
sources.
A comprehensive set of accessories such 
as ring adaptors, gooseneck fixtures, 
polarizers etc. help to fit EasyLEDs to 
almost any stereo microscope.

 The VisiLED product line is an innovative 
illumination system specially developed 
for stereo microscopy and macroscopy. 
Utilizing the benefits of white LEDs, this 
system opens up completely new possi-
bilities for putting microscope specimens 
in the right light. 
The VisiLED system features the following SCHOTT exclusives: 
  n Lightheads are controllable in segments, which enables new contrasting  
 
methods. 
  n Easy combination of brightfield with darkfield illumination or of incident  
 
light with transmitted light allows targeted mixing of light for demanding  
 
work in research, development and routine procedures.
  n Illumination parameters can be stored in memory positions, leading to  
 
reproducible mixed light conditions. Quick and easy changeovers between  
 
stored light settings.

The excellent controllability of the LEDs affords the VisiLED contrasting 
methods, which go far beyond the possibilities provided by conventional 
microscope illuminations. 
The MC1500 controller contains five preset VisiLED segment illumination 
modes.
This enables quick changeovers between shadow-free full-circle illumination 
to soft-shadow half circle or 4-point illuminations as well as to strongly direc-
tional illuminations. Rotating these directed illuminations around an object 
intensifies surface structures and optimizes contrast. 
Additional contrasting options are achieved by combining of two VisiLED 
illuminations. 
For example: 
n	 The incident darkfield ringlight enhances structures on flat surfaces but 	
	
also creates black shadows in recessed openings. Adding a small amount 	
	
of brightfield illumination softens these shadows and makes inspection of 	
	
the recessed openings possible. 
n	 Certain translucent objects are normally inspected with incident light, e.g. 	
	
crystals in geology. Adding transmitted light and optimizing the illumi- 
nation direction helps considerably to intensify contrasts considerably.
Continuous rotation of a directional 
illumination increases the impression 
of three-dimensionality with structured 
specimens, especially when viewed on  
a monitor.
In flash mode the defined mixed light 
can be momentarily enhanced by an 
intensive single pulse: exposure times 
of connected photo equipment can be 
reduced – the mixed light “flashes”. This 
is important when documenting weakly 
reflective specimen.
The possibility of storing, archiving and 
easily reproducing the high contrasting 
light conditions together with the op-
tion of controlling the VisiLEDs from PCs 
makes the system the ultimate choice 
for investigations in the field of forensics.

VisiLED
Lightheads
All VisiLED illuminations are optimized for microscopy use. Strongly focused 
illumination areas as well as the working distances and adaptation diameters 
match with common stereo microscope objectives. 
Highly intensive cold light is brought precisely to the specimen – heat-free 
and with the best quality white of approx. 5,600K CCT.
The product line comprises:
Brightfield ringlights for high intensity incident light illumination with 
80 or 40 white LEDs
n	 Ringlights S80-55 and S40-55 with minimum working distance of 55 mm 
for objectives up to magnification 1
n	 Ringlight S80-25 with working distances of 25 - 50 mm for higher 
	
magnifying objectives
Darkfield ringlight S40-10D for an intensive illumination in the incident 
darkfield, enhancing contrasts of flat structured surfaces. It can be mounted 
on 58/66/70 mm objectives via an adapter ring or easily be combined with 
all brightfield ringlights using the brightfield-darkfield adapter kit. 
Transmitted light bases for excellent 
contrasting of transparent objects
n	 The compact VisiLED transmitted 
light stages TLS-BF for brightfield  
and TLS-DF for darkfield fit in all 
common stereo microscope stands.
n	 The VisiLED ACT base (Advanced 
Contrast Transmitted) sets new  
standards for examing the structures 
of low-contrast, uncolored specimens. 
It combines transmitted light bright-
field and darkfield illuminations, all 
settable as shadowfree or as oblique 
light illuminations. Additionally, two 
mechanical diaphragms enable a high 
end relief contrast for low-structured 
transparent samples and phase speci-
men that are scarcely recognizable in 
the direct brightfield.

Controllers
 Controllers have been specifically developed for the VisiLED Series microscopy 
illumination system.
MC1500 – the intelligent multifunction center
The MC1500 is the core of the VisiLED system. It controls up to two illumi-
nations simultaneously and thus offers easy combination of any two VisiLED 
lightheads. The MC1500 allows the setting various illumination parameters 
including light intensity, different segment modes and change of illumination 
direction. Additionally, the controller offers rotating, strobing, external trigge-
ring or flashing of the LED light, ensuring constant mixed light characteristics 
through its synchronized control of the connected VisiLED illuminations.
Different mixed light settings can be permanently stored in the memory 
section of the MC1500, quickly reproducible using the controller keys or a 
foot switch. The MC1500 can be completely controlled by PC or laptop via 
RS232 interface or USB. It allows exact parameter settings and expanded 
segment control. A windows demo software and a DLL to integrate in custo-
mer software are included. 
The LED temperatures in each VisiLED 
illumination are continuously monitored 
by the MC1500. This thermo guard 
ensures a long lifetime of the white 
LEDs – even when set at the maximum 
brightness level. 
Additional accessories: a flash cable, 
a foot switch and a RS232-to-USB1.1 
converter
MC750
A controller for lower contrasting 
requirements. The MC750 has contin-
uous dimming via potentiometer and 
over temperature protection of the 
LED lighthead.
