Levenhuk 500B Binocular Microscope Magnification: 40–1000x. Binocular head, achromatic objectives, halogen light with a collector Use a Levenhuk 500B Binocular Microscope in a laboratory to study stained microscope slides of plant and animal tissues. Due to the halogen light, the entire color range will be transmitted as accurately as possible, and the contrast of details will impress even the most demanding researchers. This microscope is a great choice for a biochemist, microbiologist, or veterinarian. The microscope features wide-field eyepieces with 10x magnification and achromatic objectives with 4x, 10x, 40x, and 100x magnification. The binocular head is conveniently inclined at 30°; what's more, it is rotatable. The optics allow for examining samples at magnifications from 40x to 1000x using a bright field method as well as oil immersion. Two objectives feature front lens protection (a spring-loaded frame): 40x and 100x ones. Immersion oil is used with a 100x objective. The microscope is equipped with a stage with a mechanical scale that helps to place the specimen accurately under the objective. Under the stage, there is an Abbe condenser with adjustable height with an iris diaphragm. You can install a light filter in a special holder. Powerful halogen lighting is equipped with a collector; there is a brightness adjustment. The lighting is powered by an AC power supply. All of the optical elements in the microscope are made of glass. The body is made of metal.
