M500B-MS-MT Digital Monocular Compound Microscope, WF10x and WF20x Eyepieces, 40x-2000x Magnification, Anti-Mold Optics, Tungsten Illumination, Brightfield, Abbe Condenser, Coarse and Fine Focus, Pla

The M500B-MS-MT digital monocular compound microscope has interchangeable 10x and 20x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, tungsten illumination, coaxial separate coarse and fine focus, a 1.25 NA Abbe condenser, and a plain stage with a mechanical specimen holder. The 1.3MP camera has a CMOS color sensor, a reduction lens, image capture and editing software, and USB 2.0 output to capture or display still or video images on a computer or projector. The monocular viewing head has a fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing.

An anti-mold head preserves optics in high-humidity areas. The forward-facing revolving nosepiece has 4x, 10x, 40xS, and 100xS (oil) DIN achromatic objectives that provide color correction of magnified images. The 40xS and 100xS objectives are spring loaded to prevent damage to the slide or objective when focusing. The 100xS oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. The fully-coated optical system provides sharp, high-resolution images. A digital compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired, and where image capture, detailed records, or documentation is required.

The 1.3MP digital camera has a CMOS color sensor for displaying still microscopy images and streaming live videos to a computer or projector. The camera has 40x magnification and a built-in 0.5 x reduction lens that ensures that the display has a similar field of view as the microscope eyepiece. The camera can be mounted in a C/CS-Mount or any 23mm eye tube. The camera includes image capture and editing software that provides still image and live video capture and editing. Measurement functions including length, area, and angle. The software supports JPEG, BMP, TIFF and RAW, and is compatible with Windows (32- and 64-bit XP, Vista, 7, and 8), and Mac OS X (32-bit).

Camera drivers are compatible with Windows (XP, Vista, 7, and 8), Mac OS X, and Linux. The camera has a USB 2.0 data port (cable included). The microscope has lower (diascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. Tungsten (incandescent) illumination provides bright light, and a rheostat controls the amount of light emanating from the lamp. The 1.25 NA Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize the amount of light illuminating the specimen.

The condenser is controlled using a spiral mechanism. The plain stage has clips to secure the specimen in place, and is 4-3/8 x 4-3/4 inches (110 x 120mm) (W x D; where W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). A mechanical specimen holder can be added to the plain stage to provide precise movement, perform measurements, and record coordinates. Separate coaxial coarse and fine focus eases focusing for left- and right-handed viewers, and a rack-and-pinion mechanism provides precise and secure focusing.

Focus tension control prevents stage drift. All the mechanical parts of the microscope are constructed of metal to provide durability and resistance to wear. The metal frame has a stain-resistant enamel finish for durability and to ease cleaning.
