3、 Instrument features

▲ Microscope frame
Following the theory of ergonomics, a series of convenient and comfortable designs have been adopted from the perspective of user usage.
uniqueThe Y-shaped rack provides a stable structure and wider usage space.
The low hand position focusing operation and stage adjustment design minimize operational fatigue to the greatest extent possible.
The simple and touchable dimming handwheel and the random limit function of the loading platform make operation easier and more comfortable.

▲ Observation tube

A hinged observation tube tilted at 30 °, with a range of pupil distance adjustment of 48-75mm.
YRS-25Observation tube can be equipped with22mm field of view eyepiece, with a large field of view eyepiece, makes search faster and more convenient.
At the same time, an optional eye height sensor is provided. Users can set according to different observation heights.

▲ Ergonomic Observation Tube
Meet the requirements of ergonomics observation and reduce the fatigue of long-term observation.
Variable angle binocular observation tube, head angle range: 4-30 °, Pupil distance: 55-75mm.
Ergonomic binocular tubeHead angle range: 4-30 °, Pupil distance: 55-75mm, head stretchable range: 0-35mm.

▲ Eyepiece

Combined with an infinite optical system, equipped with a flat field and high eye point10X18mm high eye eyepiece.
Even if observed for a long time, it can ensure that the user operates comfortably without fatigue.
Eyepiece diopter adjustable device, convenient for users to adjust according to their vision.
In addition to standard equipmentIn addition to 10X, there are other multiples of eyepieces available for selection. The eyepiece can be equipped with a reticle.

▲ Converter
The converter adopts an internal positioning mechanical structure to ensure accurate positioning and smooth conversion when converting different multiples.
Five hole or six hole converters are available for customers to choose from for different configuration requirements.

▲ Objective lens
New Series of Infinite Distance System Design The objective lens isYRS-25Provides the best optical imaging quality. The lens adopts multi-layer broadband coating to increase transmittance and improve image contrast.
Lead free optical materials comply withROHS environmental requirements.
Excellent aberration correction performance improves the flatness and resolution of the field of view, and superior optical performance maximizes color reproduction.
Positive phase contrast objectives, like bright field objectives, have the best quality and exquisite craftsmanship.
The improvement of the working distance of the objective lens provides sufficient operating space for the operator and effectively ensures safe switching from oil immersed objective lens to dry objective lens.
At the same time, the combination of objective optical design and diameter compensation design forms a fully calibrated intermediate image, and high-quality digital microscopy images are obtained through a three lens tube.

▲ Mechanical stage
The mechanical stage adopts a hard and wear-resistant surface, high hardness, and corrosion resistance.
Platform travel76x52mm, equipped with rotation and torque adjustment devices for convenient user control of X and Y axes.
The left and right hand loading platforms are available for customers to choose from, with the minimum reading of the loading platform cursor0.1mm.
The increase in the distance between the positioning holes of the double clamp on the stage enhances the stability and durability of the clamp.

▲ Focusing lens
standard configurationN. A. 0.90/0.13 swing in/out achromatic condenser lens, suitable for observation of 2X-100X objective lenses.
The height of the spotlight can be adjusted by the spotlight adjustment handwheel.
The center of the spotlight can be adjusted by a pair of adjustment paddles on the spotlight holder.
N. A.0.9 Abbe spotlight (can be equipped with phase contrast push-pull plate) and turret phase contrast spotlight are available for selection.

▲ Lighting
Collecting mirror is enlargedmicroscopeThe aperture of the optical component reduces diffraction effects under large aperture illumination.
The 6V/20W halogen lamp Kola illumination system becomes a powerful guarantee for the imaging resolution and brightness of microscopes.
dedicatedThe 3W LED module is designed to be interchangeable with 6V/20W halogen lamps, making it easier for users to switch lighting.
The collecting mirror holder is equipped with a threaded filter cover, which allows the filter to be built into the collecting mirror to prevent it from falling off when the microscope is moved or stored.

▲ Phase contrast dark field observation attachment (optional)
YRS-25Provide a simple operation plug-in board suitable for phase contrast and dark field observation.
Phase contrast observation adopts optionalN. A.0.9 Abbe condenser lens, combined with different magnification phase contrast objectives 10X, 20X, 40X, 100X and corresponding PH1, PH2, PH3 phase contrast inserts for use. The dark field plug-in board is suitable for 4X-40X magnification observation.
