20x-40x-80x Binocular Stereo Microscope

Part #: G322A

Q & A about this item (ask the sellers before you buy):

Q: What are the types of lighting? Do they have intensity adjustment?
A: For this item, both upper and lower lights are halogen. Halogen lights are much brighter than tungsten lights. With the upper light reflector, the light is more even and focused. Another important feature is the intensity (brightness) adjustment. Appropriate lighting is essential for viewing, and even more important for photographing. Like using a camera, over lighting or under lighting will not show you the best details. This microscope comes with intensity adjustment for both upper and lower lights and each can be adjusted separately. Most low-end microscopes don't have intensity adjustment.

Q: How long is the working distance and why it's important?
A: Working distance is the distance between the bottom of the objective to the surface of specimen you need to focus on. This item has a working distance of 3-5/32" (80mm). It has the option to add an auxiliary 0.5x lens to increase the working distance to 4-3/4" (120mm). Large working distance allows you to have large free room to proceed any operation. It also gives you more lighting options, e.g. ring lights, cold fiber lights.

Q: Is it easy to attach an auxiliary reduction lens to increase the field of view as well as working distance?
A: Field of view is the maximum size of the object you can see through the microscope. This microscope has a 48mm thread on the bottom of the objective housing so it can be attached an auxiliary lens. Auxiliary lenses could be 1.5x, 2x or 0.5x and 0.5x is most commonly used. With a 0.5x lens, you may almost double the field of view and also increase the working distance by 1.5x-2x. Some low-end stereo microscopes, from other sellers, don't have the ability to attach the auxiliary lens. We do carry the low-end microscopes, but sell at lower prices.

Q: What is the size and weight of the microscope?
A: Commonly, the larger and heavier, the better. The size of this microscope is 9-7/16" x 5-7/8"x14-1/8" (24cmx15cmx36cm) and the net weight is 9 lb 10 oz (4.4kg). It's not the high-end stereo microscope but the size and weight are outstanding at its price. Do not be fooled by the package weight.
