AmScope T390B-PCS White Trinocular Microscopes sku-40243699

The AmScope T390B-PCS is a White compound trinocular microscope listed under Microscopes. It has interchangeable 10x and 20x widefield eyepiece pairs and a forward-facing nosepiece with four DIN achromatic objectives: 4x, 10x, spring-loaded 40xS and spring-loaded, oil-immersion 100xS. These provide eight magnifications and color-corrected images.

The 40xS helps protect slides while focusing; oil improves resolution with the 100xS. The title lists 40X-2000X magnification. Its sliding binocular mount adjusts from 55 to 75mm between pupils. The head has a fixed 30-degree inclination, 360-degree rotation and dioptric adjustment. A camera can attach to the vertical trinocular port with a 23mm or C-Mount adapter; the camera is sold separately.

Transmitted brightfield illumination uses a halogen lamp to light translucent or transparent specimens from below, producing a dark image on a light background. The rack-and-pinion 1.25 NA Abbe condenser has an iris diaphragm to adjust illumination. The double-layer mechanical stage holds and moves a slide along the X and Y axes, with 1mm divisions for recording positions.

It measures 5-1/2 x 5-1/2 inches (140 x 140mm), with a travel range of 3 x 2 inches (75 x 50mm). Graduated coaxial coarse and fine focus permits measurements. The enamel-coated cast-steel body resists stains and corrosion. Specifications include a 6V/20W halogen light, auto-switching 110V/220V power and a weight of 10lb. /4.5kg.

Compound microscopes use an objective and eyepiece for two-dimensional images; stereo microscopes show depth, while digital models display images on a monitor. Monocular, binocular and trinocular models have different eyepiece arrangements. Magnification describes image size; resolution describes clarity and depends on field of view, numerical aperture and working distance.
