## Overview

The AmScope T690C-PCT200-PL Phase-Contrast Trinocular Compound Microscope is designed for high-level biological research and educational applications, featuring a magnification range of 40X to 2500X, super-widefield eyepieces, and advanced optical components for superior clarity and ease of use.

## Description

The AmScope T690C-PCT200-PL compound trinocular microscope has a Siedentopf binocular mount with interchangeable pairs of 10x super-widefield and 25x super-widefield eyepieces, a reverse-mounted nosepiece with four DIN infinity plan achromatic objectives, four turret-mounted phase-contrast objectives, Brightfield halogen illumination, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. The trinocular head has a vertical camera mount and a Siedentopf binocular mount with interchangeable pairs of WH10x and WH25x eyepieces, 55 to 75mm Siedentopf interpupillary adjustment, a fixed 30-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to provide a more comprehensive view and enable sharing. Dioptric adjustment accommodates individual eye-strength differences. The vertical trinocular port accepts a camera with a 23mm or C-Mount adapter (camera sold separately). The mechanical tube length is 6-5/16" (160mm). The reverse-mounted revolving nosepiece has 4x, 10x, 40xS, and 100xS (oil) DIN infinity plan achromatic objectives that provide color correction, focus over the entire range of the viewing field, and a longer working distance for improved focus when auxiliary components are utilized. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. Four plan phase-contrast objectives (10x, 20x, 40x, and 100x) and corresponding condensers provide high-contrast images. Plan objectives provide improved focus over the entire range of the viewing field. The turret eases magnification changes. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.The microscope has Brightfield and phase-contrast illumination. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. Phase-contrast provides high contrast and visibility without the use of stains, allowing specimens to be observed in their natural state without being killed or fixed. Halogen light source provides bright light in a concentrated path, and a Kohler condenser focuses and centers the light path using two iris diaphragms, providing optimum contrast and resolution. The graduated double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. A stage stop prevents the stage or specimen from coming into contact with the objectives. The stage is 7.1 x 5.9 inches (180 x 150mm) and a traveling range of 3 x 2 inches (75 x 50mm). Graduated coaxial coarse and fine focus has a focusing range of 1-3/16" (30mm) and fine-focus divisions of 0.002mm (0.0000787") that enable measurements to be taken. Focus knob tension control prevents the stage from drifting out of focus. The cast-alloy enamel-coated body is durable and resistant to stains and corrosion.

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.United Scope manufactures microscopy equipment and accessories under the brand name AmScope.

## Customer Reviews

### ⭐ Condenser ring not same as in pic and, as a result, cannot use phase contrast kit!!!
*by T***R on July 11, 2021*

So, I had to already return the first of these I bought as the head was damaged and wouldn’t stay in place. So, this is my second and this one has a condenser ring assembly with a closed ring. As such, that makes the maximum height of any condenser it can use no more than 9mm. However, this phase contrast condenser has a height of 13mm. When I look at the pics showing of the microscope it does not have the same stage assembly as mine, specifically the condenser ring assembly. The one shown in the pics has an open ring assembly, thus allowing the taller phase contrast condenser to slide into place. However, as before, my ring assembly has a closed ring and thus blocks the taller phase contrast condenser from being able to be placed. Getting REALLY mad. Seems like a Mickey Mouse operation, but, then again, I don’t want to insult The Mouse as at least Disneyland runs with precision and professionalism. Where was this built? A spare bathroom in an abandoned building tilting to the left, with spare parts and the lights out?

### ⭐⭐⭐⭐⭐ Trouble with immersion objective
*by M***. on November 18, 2020*

I bought a Amscope microscope, and kept within box until 2 months later. So, with some use, this objective was not working anymore: final lens unglued, and worst, immersion oil was spread insight objective's body. My Hope is that you warrant a brand new objective, since ita was not related with misuse. Anyway, I really appreciate this microscope: robust precise and very qualified optics. I am sure my next microscope will be American Opticl again.
