Ideal for advanced high school, biology, college, veterinarian, medical, or technical applications, the Swift Optical M3802CB-4 Binocular Cordless LED Microscope is a versatile microscopy device that can be easily brought into the field and used where there are no conventional power outlets.

A Siedentopf-style binocular head is set at a comfortable 45° angle to the body for a natural and comfortable viewing position with the ability to rotate the head assembly a full 360°—making it easy and convenient for multiple people to share the eyepieces. The head is equipped with dual 10x eyepieces that, when combined with the objectives, produce magnifications from 40x to 1000x. Semi-plan objectives present a flat field of view across about 80% of the center portion, so the only noticeable curvature (spherical aberration) will be around the edges of the view. The objectives are all parfocal and parcentered, so that little or no focus adjustment will be required when changing magnifications, and the center of the view will remain consistent between objectives.

Its dual-speed coaxial focuser features a tension adjustment on the coarse adjustment so there is no slippage when the knob is released, and the fine focus knob is graduated, allowing differential measurements to be recorded. A large 5.75x4.75" stage has integrated rulers and slide clips as well as specimen holders to make it easy to view a variety of specimen types. The lower cool-white LED illumination has a rheostat to control the intensity and is directed through a 1.25 N.A. Abbe condenser with an iris diaphragm to give you extreme control of the light coming through to the stage. Utilizing current LED technology delivers higher light efficiency than a conventional tungsten bulb with a cool operating temperature that prolongs specimen life when viewing live material, while also being energy efficient to extend battery life.
