A trinocular microscope is simply a laboratory microscope with an extra eye. While its binocular eyepiece objectives work as your seeing eye into the interior of a cell or the tissues of an animal or plant, the third objective is for mounting your camera. In the past, microscopes had to be kept in extremely good condition, because the camera had to share lenses with the eyepieces. Any damage done to the eyepiece objectives would change the pictures or moving images produced.
Of course, the rotating objectives of the microscope have a great share in contributing to the quality of the image produced as well, and they have to be cared for whether you are working with a binocular or trinocular microscope. However, with a trinocular microscope, you have much less to worry about, as you have a separate lens for use with your camera. Add to this advantage the fact that trinocular microscopes are now digital, and you have for yourself quite a good deal in terms of laboratory equipment.
Digital trinocular microscopes not only allow you to mount a digital camera onto the trinocular mount, but some models may also allow you to preview your specimens before you even take any pictures or capture any moving images. This is possible through a mounted external monitor, which will also allow your colleagues to see the same images that you are looking at through the binocular eyepiece objectives. Although such digital trinocular microscope models are expensive, they can be helpful in conducting classroom discussions on basic techniques in microscopy.
Trinocular microscopes, in general, will require different accessories in order to keep them in working order. The foremost would be the photo and video trinocular microscope accessories. If you have a preview screen, you might be working with an LCD monitor that can be easily damaged by frequent touching. This LCD preview screen is quite expensive, so if you have a trinocular microscope with such a screen, exercise great care in handling it and make sure that it is plugged into a voltage regulator. Sudden power surges or losses can damage the quality of your image and the integrity of the LCD monitor.
There are different options in terms of digital cameras, but you will want a model that can take the best pictures or moving images of your specimens. In general, you might want a high resolution camera, or, the higher the megapixels, the better for your laboratory. This is because many scientific peer-reviewed journals will accept only high-quality photos with excellent resolution. So by investing in a high megapixel camera, you are ensuring easier and faster acceptance of your specimen images not only by these scientific peer-reviewed journals, but by conference organizers as well.
If you want even higher magnification, you can opt for the oil immersion objective, which utilizes a drop of oil to establish continuity between the glass of the objective lens and the glass of the slide that you are viewing. In establishing continuity, an image can be further magnified, and light is kept from dispersing. An oil immersion objective, however, can be very expensive, so purchase this accessory only if you absolutely need high magnification for your class or research procedures. Other microscope manufacturers will offer varieties of objectives, such as those featuring extremely high contrast, or achromatic ones.
The light source for this kind of microscope can be bought as an accessory, especially if the original light bulb has outlasted its life. Halogen bulbs are commonly used for trinocular microscopes, so be sure to specify the model number of your microscope when shopping for light bulbs. This will ensure that your halogen bulb will fit the microscope exactly.
Other accessories can include light filters, which can improve your viewing. Light filters work well with different specimen stains, so if you are working with mammalian cells, or with bacterial cells that need specific staining techniques to be seen, then you may want to buy light filters to add to your trinocular microscope. These are only a few trinocular microscope accessories that you might want to buy. There may also be different adaptors for the different kinds of cameras available, so ask your manufacturer for more information on what kinds of cameras are compatible with the trinocular microscope you are working with.
