Warranty

Specifications

The Revelation III is covered by a limited lifetime warranty on materials and workmanship and

1-year warranty on electronics from date of purchase. If there is any indication of a problem,

contact LW Scientific. Operating the unit after noticing a problem could compound a simple

problem and cause an unneccessary expense to the owner. LW Scientific support staff will

troubleshoot problems over the phone and attempt to solve problems in the most expedient manner. This may include

sending parts that can easily be installed by the user, or directing the user through a simple adjustment to the unit.

Making repairs to the unit without authorization from LW Scientific will void the warranty.

If the unit must be shipped in for repair, LW Scientific will issue a Return Merchandise Authorization (RMA) number. You will

need to provide the serial number and have either a warranty card on file at LW Scientific or proof of purchase.

Introduction

The LW Scientific Revelation III microscope is our best-selling medical-grade compound microscope, popular in physician

and veterinary offices as well as universities and medical schools. Its crisp optics, sturdy design and proven track record

make the Revelation III the best choice for superior performance at an economical price. The Revelation 3 microscope is

intended for use as a biological microscope in a professional environment in accordance with the guidelines set forth in

this operations manual.

Not all features available on all models -

see back page for model specifications.

Four Head Choices

1Always cover your microscope with the dust cover when not in use.

When cleaning the lenses, use lens paper or a cotton swab dipped in lens cleaning solution.

Excess oil should be cleaned off your 100x objective and stage at once. An alcohol pad is best for removing oil from

the stage and on the other metal parts, but is not recommended for use on the lenses. Use lens cleaning solution and

lens paper to clean off your objectives.

Dust in the nosepiece or ocular tubes should be blown out using filtered air. Canned air dusters work well for this job.

Whenever you remove an objective, we recommend that you place it back into the original plastic shipping vial until

ready to be placed back on the microscope. SCREW THE OBJECTIVE SECURELY INTO THE CAP OF THE HOLDER - DO NOT

DROP OBJECTIVE LOOSELY INTO CONTAINER.

To keep your microscope in top condition for years, LW Scientific recommends that you have the microscope

professionally serviced once a year. Warning: The 40x objective is not sealed for oil immersion. Damage to the 40x

objective due to oil immersion is not covered under warranty.

Unpacking and Setup

Assembly

Operation

LW Scientific packs each Revelation III Microscope with utmost care.

Examine the outer and inner containers for any visual damage. Retain all of

the packing material until you have examined and tested your new

microscope. If there is damage, please contact the shipping company, as

our warranty does not cover shipping damage. If you are uncertain who the shipper is, contact the distributor from whom

you purchased the microscope. Please retain all packaging material for future use. Carefully unpack** your Revelation III

Microscope using the following checklist for all the parts and accessories:

1 - Microscope body with Abbe condenser

2 - 10x eyepieces

1 - Binocular head (Seidentopf style)

1 - Mirror and attachment device for field use

2 - Filters (blue & green)

4 - Objectives 4X, 10XR, 40XR, 100XR (oil)

1 - Power Adapter

1 - Warranty Card

1 - Immersion oil

1 - Dust cover

**Note: Some parts may be packed in the

outer recesses of the Styrofoam blocks

Power

1Remove the body of the microscope and place it on a sturdy, dust-free surface. Remove the plastic plugs in the nose

piece. Install the objectives in such a way that when you turn the nosepiece clockwise, you are moving from the 4x,

Insert the 10x eyepieces.

Attach the power adapter.

4For protection during shipping your Rev III is shipped with the stage locked in low position. To disengage the lock,

pull the STAGE LOCK LEVER towards the rear and downward. The stage should now move upward freely.

Remove the microscope head from the Styrofoam carton and pull off the protective covers from the

eyepiece tubes and head mount. Insert the head mount into the upper arm of the body. Using the

head retention screw, secure the head in place. Note: Do not over-tighten.

Once you have assembled all the parts and allowed your microscope to come to room temperature, plug the

power adapter into the microscope and then into the appopriate AC outlet. Note: Excess cold can fog lenses

and cause lamp to fail.

Turn the light on using the black on/off switch on the right side of the base. Next adhust the light intensity using

the brightness control wheel located on the right side just behind the on/off switch.

In order to become acquainted with the controls, choose a specimen slide with which you are familiar. For

example, an old hematology slide or a commercially prepared slide. Place the slide into the slide holder by

pushing back on the thumb guard to open the slide finger. The slide finger closes slowly to eliminate the

possibility of chipping the corner of your slide when it closes.

Move the slide to the center of the stage, by turning the stage control knobs, located just below the stage.

These knobs allow yo to move the slide on the X-Y axis (forward/backward and left/right).

The sub-stage iris should then be set to match the aperture of the objective for maximum resolution under each

objective power. You should begin with the 4x or 10x objective.

4x objective 1.0 N.A. (nearly closed) 40x objective - 0.65 N.A. (halfway closed)

10x objective - 0.25 N.A. (1/4 closed) 100x objective - 1.25 N.A. (wide open)

Insert the filter of your choice into the swing-out filter holder beneath the Abbe condenser. Note that many

customers prefer to use the blue filter for routine use.

Once you are comfortably seated, look into the oculars and move the eyepiece tubes together or apart until

you see only one complete circle of light. You have now adjusted your interpupillary distance.

Using the 4x or 10x objectives and the coarse and fine adjustment knobs, bring the specimen into focus. Now,

move the 40x objective into place. You will feel a “clicking” action when the objective is seated properly.

Again, adjust focus for best image. You should also adjust the iris diaphragm (as listed above) for the best

contrast and resolution.

Diopter Adjustment: Since you are using a binocular microscope, you have to adjust the normal difference in

vision between your two eyes. This is a simple but critical adjustment! Close your left eye and look into the right

ocular with your right eye. Adjust the focus to give you the best image. Now look at the ocular tube on the left.

You will see that the left ocular tube has a built-in adjustment ring. Now close your right eye and look with your

left eye into the left ocular. Using the diopter adjustment ring on the left ocular tube, adjust the focus until you

see a clear, focused field.

Friction Adjustment: With repeated use and wear, the stage may drift out of focus. If this happens, you need

only to tighten the tension control ring (located on the right side of the microscope between the coarse

adjustment and the body of the microscope). If the coarse focus is hard to turn, you may choose to loosen the

friction adjustment.

Stage Stop Lever: To help prevent the stage from hitting the objectives, the Revelation III Microscope is

equipped with an adjustable stage stop. Rotate the 100x oil objective into place, and put a slide into the slide

holder. Slowly raise the stage, stopping when the slide makes contact with the objective. Now, turn the stage

stop lever in a clockwise direction toward you. The stage stop lever is located on the left side of the micro-

scope between the coarse adjustment and the body of the microscope.

If you suspect faulty electronics, call LW Scientific’s technical service department at 800-726-7345.
