Leica M420

Macroscope

The modular system

Thank you for your attention. We are proud to present the Leica

M420 macroscope, a Leica creation. As with a stereomicroscope,

large o jects can e viewed in their entirety and without prepara-

tion, thanks to the wide fields of view and the favoura le working

distances. However, the Leica M420 macroscope offers a vertical

eam path and a high-resolution apochromatic zoom o jective,

making it ideal for distortion-free photography, for parallax-free

measurement and for o taining correct polarization colours.

The modular system

The Leica M420 macroscope is designed on the uilding- lock

principle and can e matched to the individual requirements of

the user, and to the dictates of the workplace, at any time. This

rochure shows a large num er of com inations with appropriate

accessories. A clear assem ly diagram helps you to put together

the specific configuration that you need. If you still have

questions, get in touch with your local Leica agency or directly

with Leica Microsystems Ltd in Heer rugg, Switzerland. We will

e pleased to help. CUSTOMER SERVICE is a ig thing with us.

Not only efore the sale, ut afterwards as well.

Welcome!

The requirements

A modern macroscope must ring its user the maximum possi le

enefits and must uncompromisingly fulfil the requirements

demanded of it. Like the macroscopes from Leica, the modular

components of which can e com ined in accordance with your

wishes. Get in touch with us. We will gladly help you to assem le

the ideal outfit for your needs in examination, in training or in

documentation.

Macroscope

Macroscopes are optical precision instruments

for studying o jects in their entirety in conjunc-

tion with large working distances and large

fields of view. The multiple-coated optical

system involves a single vertical eam path

which, for purposes of comforta le o servation

in the inocular tu e, is then split into two

identical parts. The vertical o servation mode

ensures parallax-free imaging and is ideal for

faithful documentation, precise measuring, and

investigations involving polarized light.

The Leica M420 macroscope is an instrument

for optical inspection in all fields of science

and technology where image quality and user

comfort are oth rated highly.

The modular system

The optics carrier with inocular tu e can e

equipped with a Macrozoom- or Apozoom

o jective, with one of several additional o jec-

tives, with eyepieces of various intrinsic magni-

fications, and with an appropriate stand and

illuminator.

Additional accessories for photography, TV,

digital imaging, measuring and polarization can

e easily added.

Adapting any camera

The incorporated video-/phototu e will accept

most still cameras and CCD-, TV- and cine

cameras. If however a Leica modular photo-

micrographic system is used, there is a choice

etween two fully-automatic systems.

Photo eyepieces (8×, 10×, 16×) in the video-/

phototu e enlarge the image and project it into

the film plane (two-stage magnification). There

is an additional magnification factor of 1.25×in

oth the o servation eam path and the photo

eam path. The limits and sharpness of the

image can e inspected y looking into either

the inocular tu e or the focusing telescope

of the camera. The light is partitioned 50%/50%

etween o servation and photography.

Optical accessories

The requirements

Because the working distance, the total magnification and the

field of view must all e adapted to the application, the user needs

to e a le to choose from a range of high-quality o jectives and

eyepieces.

The Macrozoom- and Apozoom o jectives can

e com ined with the coaxial incident-light

housing, with a quarter-wave plate, and with

additional o jectives.

1 5 Macrozoom objective

The Macrozoom o jective is inscri ed with the

magnification range 6.3×to 32×. This means

that, if 10×eyepieces are used in the inocular

tu e (which introduces a tu e factor of 1.25×),

o jects can e o served at constant sharpness

over a zoom range from 7.9×to 40×. The optical

components are computed to give wide aperture

and good resolution, multiple-coated to ensure

high image contrast, and well corrected to

produce image fidelity and crispness.

The 0.5×and 2.0×additional o jectives can e

used with the Macrozoom o jective.

1:5 Macrozoom and 1:6 Apozoom

o jectives

1 6 Apozoom objective

The intrinsic zoom range of the Apozoom o jec-

tive is from 5.8×to 35×, i.e. the zoom range down

the inocular tu e if 10×eyepieces are used is

7.3×to 43.8×.

Because of its excellent chromatic correction for

three spectral colours and for all intermediate

tones, the Apozoom is the o jective of choice if

requirements stipulate maximum sharpness,

highest resolution and maximum contrast rendi-

tion, even for the finest structures.

The 0.4×and 2.0×additional o jectives used

with the Apozoom o jective have een specially

designed for it.

Wide-field eyepieces for spectacle wearers,

distortion-free

• Intrinsic magnifications

10×, 16×, 25×and 40×

• Usa le with or without spectacles

• Adjusta le eyecups

• Diopter setting adjusta le from +5 to –5

• Accepting graticules for measuring

and for photography

The asic outfits include distortion-free, wide-

field eyepieces (10×/21B) for spectacle wearers,

with excellent imaging characteristics. Because

of their long exit pupil distance of 22mm (at this

distance the o server sees the full field of view)

these eyepieces are usa le either with or with-

out spectacles. If you work without spectacles

and want closer contact to the eyepieces or to

the eyecups, you can displace the height of the

eyecup a ove the eyelens within the range from

4mm to 20mm.

Additional o jectives, with ayonet

mount: 0.5×and 2.0×for the Macro-

zoom, 0.4×and 2.0×for the Apozoom,

and rotata le quarter-wave plate.

New Leica motor-focus system

The new motor-focus system ena les any

microscope outfit to e moved weightlessly up

and down with light movements of the fingers or

feet, or through computer control. With the hand

control, five exact focus settings can e stored;

with the computer, the num er is unlimited, and

the instrument can travel to these positions

directly. The motor-focus system can easily e

fitted to the incident- and transmitted-light

stands and to the large swinging-arm and ta le-

clamp stands.

Information in rochure M1-267-1en.

Coarse/fine focusing

Coarse/fine drive for incident- and

transmitted-light stands

The coarse/fine focusing drive permits focusing

along the full length of the side-faced column.

The coarse drive permits focusing over long

distances; the fine drive permits fine focusing.

The focusing drive and the side-faced column,

300mm or 500mm long, are supplied already

assem led. The low-positioned, conveniently-

shaped, ilateral drive kno s ena le you to work

comforta ly with your arms supported. The ease

of movement can e adjusted individually in

accordance with the loading.

The requirements

It must e possi le to arrange the stereomicroscope work station

exactly in accordance with requirements. The instrument can

only e fully integrated into the work process if the sturdy stand

offers unrestricted access to the o ject and adequate space for

tools and jigs.

Incident-light

stand

Incident-light stand

The incident-light stand consists of a sta le

aseplate and a 300mm- or 500mm long side-

faced column. The column ears the focusing

drive and therefore also the microscope carrier

and the optics carrier. The stand also includes

a 120mm-diameter lack/white stage plate. The

ergonomic shape of the aseplate, and its soft

upper surface, provide pleasant support for the

hands of the user.

Swinging arm stands

Swinging-arm and table-clamp stands

These stands offer ample space for large

o jects such as rocks, metal o jects or circuit

oards, which can e manipulated directly on

the surface of the ench. The many possi ilities

for adjusting on the column, the horizontal arm

and the inclina le carrier rod ena le the working

area to e planned as required.

The inclina le drive housing has a lift of 128mm.

The coarse/fine focusing drive helps to focus

quickly over long distances, and to adjust the

final setting accurately.

The large swinging-arm stand is supplied with

a 550mm long column.

The ta le-clamp stand (550mm long column)

can e clamped to ench- or ta le tops having

thicknesses of etween 20mm and 50mm, and

also to machines or jigs.

Large swinging-

arm stand

system

Universal stand

The universal stand is noted for its sta ility.

Vi rations, which can cause difficulties at high

magnifications and in photography, are elimi-

nated. Large o jects, and stage carriers with

magnetic linkage that will accept various

stages, can e conveniently positioned on its

aseplate. As in the large swinging-arm stand,

the optics carrier is connected to the horizontal

arm y means of an inclina le drive housing or a

coarse/fine drive housing.

Masks and wafers can e examined with the

help of a cross stage, which is availa le on

request; it has 6in ×6in travel with rapid XY

movement and with fine adjustment.

Drive housing with coarse/fine movement

for 50mm diameter columns

When fitted to the universal stand, this unit

provides a very sta le outfit for examining large

o jects. The coarse/fine drive ena les the image

to e focused precisely at the higher magnifica-

tions and with heavy microscope configurations.
