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 eyepieces 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 reduced 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.

SCHOTT VisiLED
Enhanced Contrast for Stereo Microscopy

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 possibilities
for putting microscope specimens in the right light.

The VisiLED system features the following SCHOTT exclusives:

Lightheads are controllable in segments, which enables new contrasting
methods.

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.

Illumination parameters can be stored in memory positions, leading to
reproducible mixed light conditions. Quick and easy changeovers between
stored light settings.

Contrast Your Application

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 directional 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:

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.

Certain translucent objects are normally inspected with incident light, e.g.
crystals in geology. Adding transmitted light and optimizing the illumination
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 option 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
Ringlights S80-55 and S40-55 with minimum working distance of 55 mm for objectives up to magnification 1X

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

The compact VisiLED transmitted
light stages TLS-BF for brightfield
and TLS-DF for darkfield fit in all
common stereo microscope stands.
The VisiLED ACT base (Advanced
Contrast Transmitted) sets new
standards for examing the structures
of low-contrast, uncolored specimens.
It combines transmitted light brightfield
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 specimen
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 illuminations 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 triggering 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 customer 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 continuous dimming via potentiometer and over temperature protection of the LED lighthead.
