The T670Q-PL is designed to be a fully-scalable and economical laboratory microscope. This model adds LED-based epi-fluorescence illumination for blue-band excitation. This high-efficiency, targeted illumination system provides superior isolation for speific fluorophores. The optical system is infinity-corrected to ensure reliable, low-distortion magnification, with plan-achromatic corrections for accurate colors, excellent field flatness and edge-to-edge sharpness. A quintuple lens-turret is used, providing five levels of magnification. The Koehler-design LED illumination system provides bright, evenly-distributed light for maximum contrast and definition. Additional upgrades are available for phase-contrast and darkfield, making this microscope perfect for scaling laboratories and advanced education.

The microscope’s head is designed for precision and comfort. The super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For users with astigmatism or asymmetrical vision, both eyepieces can be independently adjusted to fine-tune focus. The switched trinocular port provides a dedicated mount for a camera to record photos or videos, and is height-adjustable to match focus with the eyepieces. The port uses our 23mm YX-type interchangeable interface which can be replaced with an optional C-mount adapter.

The quintuple objective turret provides instant access to 5 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, soil, and bacteria. The turret’s reversed orientation provides more working room above the stage. These high-quality lenses are achromatically corrected to improve resolution and color accuracy, with planatic flat-field correction to provide edge-to-edge sharpness.

The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage’s low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.

Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The LED light-source ensures cool, energy-efficient illumination with low heat for live specimens. The bright light-source is daylight-balanced to produce natural colors for imaging. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The illuminator’s field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

Fluorescence

The epi-fluorescence illumination system adds incredible versatility to the microscope. The ability to isolate fluorescing compounds allows you to target individual proteins and other nuances. The illuminator uses a variable-intensity 3W blue LED with a narrow band for improved isolation. One major advantage of LED excitation is the improved accuracy and efficacy of targeting a narrow-band. Additionally, LED illumination does not require warm-up or cool-down periods, and it adds the ability to control intensity to avoid bleaching. LEDs are also much safer than high-pressure arc-lamps, being less volatile, cooler, and absent of UV emission (except for UV LEDs, of course).
