SW24TX Trinocular Stereo Microscope Head, WH10x Eyepieces, 10X/20X/40X Magnification, 2X/4X Objective, Includes 0.5x Barlow Lens

The SW24TX trinocular stereo microscope head has a pair of 10x20mm widefield high-eyepoint eyepieces, a 2x/4x objective, and a 0.5 x Barlow lens. The microscope head has a 3" O-ring style mounting ring. The trinocular viewing head has an interpupillary range of 47 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The WF10x20mm super-widefield high-eyepoint eyepieces combine with the 2x/4x objective to provide 10x, 20x, and 40x magnification, and a longer working distance for inspecting large-scale specimens that require handling or repair.

The microscope includes a 0.5 x Barlow lens that can be added to the objective to decrease the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, dioptric adjustment accommodates individual eye-strength differences, and eye guards ensure comfortable viewing. The optical glass lenses provide sharp images, and are fully-coated to ensure high-resolution images. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected.

Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities.

Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
