The item for sale is a nice Zeiss Standard 14 microscope guaranteed to be complete and ready for immediate use in research, laboratory, or classroom applications. For an example of the capability of this microscope, please see the last photograph, which shows cell division in an onion root tip.
It has a four-place nosepiece containing four (4) authentic Zeiss achromatic objectives, as shown in the pictures. The specifications of the objectives are as follows: 3.2X/0.07, 10X/0.22, 40X/0.65, and 100X/1.25 oil.
The binocular head is in good condition. It was made according to the Siedentopf design.
In this design, the tube length is not changed when the Interpupillary distance is modified. Two Zeiss C 10x eyepieces are included with the microscope, and are in good condition optically, and yield nice crisp high-contrast images. The head itself is affixed to a circular dovetail mount, so it can be positioned anywhere within 360 degrees horizontally. The substage condenser is fully focusable and is capable of 0.9 n.When the condenser iris diaphragm is wide open. When low-power objectives are in use, the top element can be flipped out of the way so that the field of view is completely filled with light.
The stage is an authentic Zeiss product. It is made of painted aluminum, rather than plastic, and shows neither excessive wear nor any other problem. The mechanical stage has controls which move smoothly and easily, serving well to hold and reposition a specimen. The slide clip holds specimens with adequate force, but is easy to control in order to avoid chipping the corners of glass slides (the amount of force is adjustable). The base contains both a field diaphragm and the illumination system.The illumination comes from an LED chip that has been installed in place of the original halogen bulb. LEDs run much cooler for a given amount of light than do incandescent or halogen bulbs. As a consequence, LEDs can be brighter and much longer lasting.
Moreover, the light that it gives off is truly white and doesn't change color significantly as you change the intensity. Because the light is brighter than the original, the microscope will be supplied with a neutral density filter to reduce the light intensity to a more comfortable level as seen in the photographs. The filter is not a Zeiss product and was made for certain drone cameras, but works nicely for this application. It is not attached, and any filter can be substituted, if desired. The coarse and fine focus are the usual design for these microscopes and are in good working condition.Cosmetically, this microscope is in excellent condition for it's age. To evaluate the cosmetic condition further, please take a close look at the photographs. The Zeiss Standard 14 is a true classic microscope, but the supply seems to be gradually diminishing. Combine great optics with precision mechanical components and rugged design, and what could be better? This is a great instrument for anyone, young or old, who is serious about microscopy.
Furthermore, I would be remiss, if I didn't mention that this fine instrument would make a great present for any microscopist, young or old. Why should anyone have to attempt to make do with dysfunctional Chinese trash, while these top-quality microscopes are still available restored to good condition? Zeiss optics have the stellar reputation that they do for a reason, and this microscope has been rigorously tested and is working in all respects. As with a lot of things, there's the best and then the rest.The item "Carl Zeiss microscope, Standard 14, binocular, 4 objectives, 10x oculars, LED" is in sale since Wednesday, January 16, 2019.
