Main Features:

  • Mounting Frame on Stage is able to hold a 65mm petri dish as well as a standard glass slide 25x75mm.
  • XY stage slider movement.
  • Six-place objective nosepiece.
  • Light path selector – Camera – Eyepieces.Two positions.100% to eyepieces or 70% to photo port and 30% to eyepieces.
  • Ability to shut out extraneous light from the eyepieces that may enter the camera optics.
  • Eyepieces: Pl 10x/20 High Eyepoint with ability to use eyeglasses when viewing. Note these are the better field of view 20mm instead of the cheaper 18mm.
  • Includes rubber cupping eyeguards for cutting out light from the room, important for viewing low illumination fluorescing.
  • Included all needed power cords.
  • DOES NOT INCLUDE CAMERA OR LAPTOP. Camera is shown in images to demonstrate that one can be connected.
  • Includes original Zeiss C-mount adapter for attaching a camera.

Fluorescent Illumination – Rear Light System:

  • HBO 100 Lamp Housing and External Power Supply for included 100W Mercury Bulb.
  • Luminous Field Iris Diaphragm on epifluorescence light path.
  • Filter slider / shutter for epifluorescence. Has ND filter installed. This can be used when the full intensity of the 100W bulb is not needed. Full intensity will increase autofluorescence and bleach your probes faster. Has two other empty slots capable of holding other ND filters. Pushed all the way to the side will engage the shutter to block all light.
  • Open filter slot for holding loose exciter filters, 32mm diameter.

Transmitted Light – Upper Light System:

  • 12V-100W Halogen.
  • Transformer is built into the main frame and not an external unit.
  • Rotary Turret style light Condenser with phase contrast settings.
  • Numerical Aperature. 0.3 N.A.
  • Settings for: Ph1, Ph2, Brightfield. With iris diaphragm.With centering ability.
  • Compare this higher grade transmitted light system to the cheaper version that is 6V-20W and with a simple phase slider bar.
  • Daylight blue compensation filter. Plus one empty filter slot that could be used for an optional Interference Green filter.

Objective Lenses:

  • AchroPlan, 4x/0.10, Infinity/-. Part# 440020. (some text lettering is worn off)
  • AchroPlan 10x/0.25 Ph1, Infinity/-. Part#440031.
  • LD AchroPlan 20x/0.40, Korr, Ph2, Infinity/0-1.5. Part#440845
  • LD AchroPlan 40x/0.60, Korr, Infinity/0-2.Ph2. Part#440865.

Fluorescence Dichroic Filters:

  • Filter Slider with three settings:
  • UV: Ex. 360/40. (no visible wear). (tested great)
  • Blue: Ex. 450-490 (no visible wear). (tested great)
  • Green: Ex. 545/30 (significant wear). (tested great)
  • There is no open space for Brightfield and Phase Contrast Observation. So to view those, you need to pull out the slider tray. You could also remove one filter set and that be your setting for brightfield and phase.


  • This microscope is in great condition.
  • We are including a phase centering telescope for viewing alignment of phase annulus in condenser with phase ring in objective. We are also including the needed tools for centering the phase annulus.


  • This is a high quality Zeiss (Made in Germany) optical instrument. We also sell Chinese made fluorescence microscopes but the quality is substantially lower. We highly discourage buying the Chinese microscopes due to the problems that incur after the sale. Even years old Zeiss equipment still beats any brand new Chinese microscope with image quality.

Optional Accessories:

  • We have a wide variety of optional scientific cameras, both monochrome and color, with and without Peltier cooling.
  • Optional Interference Green Filter.Great for Phase Contrast imaging.
  • Other stage mounting plates are available for use with other sizes of petri dishes and cell culture vessels.
  • DIC is not an option for this frame. If you need DIC, we have other units.
  • Other objectives can be configured.
  • We can provide brand new replacement 100W HBO Mercury Bulbs and Halogen bulbs.
  • We can install brand new Chroma hard coated filters (with lifetime warranty) instead of the used filters that are included. Cost is USD $450/ea for the dichroic filter set (emission filter, dichroic mirror, barrier filter).

Fair Market Value – Discount Price:

  • Fair Market Value USD $8,200.00.
  • Discount Price USD $7,200.00.
  • We did not find any complete comparable models for sale by others.
  • We found one at $11,000 and one at $17,500. Both have obsolete parts and will need new stages. Another was $15,000 and had an old LSD unit that would need to be removed and some parts replaced.
  • In addition, we are including a one year warranty, money back guarantee, and free shipping that are value added additions not given by most resellers and should be added to the value.

One Year Parts and Labor Warranty:
We warrant this Microscope to be free from defects due to normal usage in normal operating conditions for a period of one year. Camera equipment (if included) is given a three month warranty. Objective lenses are excluded from warranty.
Additional warranty on microscope may be purchased if desired.

We will repair or replace equipment at no charge, during the one year warranty period. Both parts and labor are included. Buyer is responsible for shipping costs BOTH ways, paying for shipping cost to our designated repair facility and shipping cost back to buyer. Bulbs are considered user replaceable items and not covered.

Warranty Excludes Objective Lenses:
Our warranty excludes the objective lenses. There are several reasons for this. First of all, if the objective is good, it will continue good performance unless there is some user or environmental abuse. Abuse can be from oil getting on a non-oil immersion lens, contact with a solution that degrades the cement around the glass, contact with other chemicals that may stain, etch or pit the glass, scratching the lens by incorrect cleaning methods such as cloths not of lens cleaning quality, damaging the lens by scraping it on slides or metal slide holders on the stage, dropping on a hard surface, subjecting the objective to extreme humidity causing internal mold or mildew, etc.
In addition, objectives can’t feasibly be repaired. If an objective is damaged so that the optical quality is significantly diminished, it is suggested to throw it away. One solution is to send it back to the factory and incur a repair fee equal to about half the price of a new replacement. That is usually cost prohibitive. We professionally clean the front and back lens, and the outside barrel of the objective. But we do not open them up. That should only be done by the factory under strict conditions and with optical laser alignment. Generally, when someone other than the factory messes with a lens, the performance may still be acceptable, but likely will be noticeably lower quality when compared side by side with a new lens. So since defective objectives are generally thrown away, and replaced with another one, there is no need to warranty them. The user can easily find a matching objective and replace it on their own.

Objective Lenses – Condition:
All objectives have been professionally cleaned.
All are guaranteed to be free from optical defects. If any defect is found, it will be clearly noted in the ad.
Our inspection of the objective lenses includes checking for the following:
lens cracking, pitting, lens cement not intact, internal oil damage or oil seepage, glass fogging, glass hazing, stains on optical glass, mold or mildew stains, and delamination (separation of internal lenses).

Condition of Equipment:
This reconditioned microscope is complete and in excellent working order and has been completely checked out and serviced.

Technical Sales and Support:
Most offerings of used microscopes are by simple flippers of equipment who have obtained defective and rejected microscopes from labs discarding the equipment. They resell exactly what they got, as they got it, and without any technical knowledge of it. You can rest assured when purchasing from us that we are professional dealers who are well trained to service and provide technical support of the microscopy equipment. We test, repair and refurbish all equipment to excellent working conditions. We are well trained and able to give you technical advice including pre-sale and post-sale support.
