VS120 Virtual Slide Microscope from Evident Corporation

The VS120-S6-W slide loader system allows for manually loading one and six standard slides, respectively, along with any associated meta-data. Designed for high throughput research and pathology, the VS120-L100-W system features a highly dependable, robustly designed slide loader for up to 100 slides.

The VS120 is not for clinical diagnostic use.


Ideal for Research Facilities and Digital Learning

State-of-the-art Research Tool for Brightfield and Fluorescence

The VS120 not only creates high resolution brightfield images, but also can scan in full multi-fluorescence mode. Utilizing virtual microscopy for fluorescence imaging helps to minimize problems associated with damaging and fading of sensitive fluorescence samples.

An innovative new algorithm makes image stitching more precise than ever, enabling high-level accuracy that can be applied from small animal brain slices to large specimens. The VS120 also switches seamlessly between micro and macro observation to enable swift viewing of regions of interest and overall structures alike.


Advanced Medical Education and Collaboration

The VS120 allows multiple viewers to study virtual slide specimens simultaneously via simple server access, regardless of time and location - providing an ideal solution for medical instruction, Q&A session and remote collaboration.

Remote Conferencing and Consultation

Virtual slides can be archived to a database, enabling network-based remote retrieval at any time through the Evident Net Image Server SQL. Images are stored at high resolution, and multiple clients can review and even synchronize elements such as specific observation areas to facilitate efficient review and discussion.


High-detail, High-precision, Rapid Scanning

Always in Focus with the VS120 Focus Map

To optimize scan speed and efficiency, the VS-ASW generates a focus map using the software-based autofocus function. This allows the optimal Z-position to be determined and saved on various parts of the sample, permitting a height profile of the sample to be compiled before detailed scan acquisition.

Different maps are used depending on the type of sample being scanned, providing the best solution whatever the specimen. Numerous coordinates are selected to create the map, which gives the system an instant focus reference when scanning the slide.

Wide Range of Objectives from 2x to 100x

The VS120 comes standard with Evident UPLSAPO 2x, 10x, 20x and 40x objectives, allowing users to choose the objective most suitable for their research needs.

Automatic specimen recognition capability limits scanning to the specimen area, with high-level color fidelity and image quality. Additionally, UPLSAPO 60x and 100x oil immersion objectives are provided as an option for a VS120-S6-W configuration.

Virtual-Z with 3D Virtual Slide Production

The VS120 can scan multiple large specimens to 31 Z-planes. Multi-plane virtual slides can then be produced by simply selecting attributes such as depth for multiple areas, range, number of planes, and magnification within the virtual-Z scan mode.

Virtual-Z scanning also allows the user to adjust the image to the specific desired depth with a simple scroll of the mouse - a function particularly advantageous for the viewing of thicker specimens, such as cell clusters or cranial nerves.

Accurate Image Stitching, Regardless of Specimen Quality

The VS120 minimizes stitching errors by automatically recognizing only where the specimen exists and then integrating images of consecutive areas.A newly developed algorithm makes image stitching with the VS120 so precise, it can even capture quality composite images across large and uneven specimen regions.

High-resolution, High-sensitivity Virtual Fluorescent Slides

High-speed filter wheels of the fluorescent unit can be installed on both the excitation and observation side, enabling the swift production of fluorescent virtual slides with high-level definition and resolution. Multi-colored virtual slides also can be prepared for long-term observation, negating concerns over fading, discoloration, and degradation.

Automation Enhances Laboratory Efficiency

An optional automated slide loader with a capacity to hold 100 slides adds efficiency to laboratories with high-throughput requirements. Furthermore, specimen information can be automatically read using 1D and 2D barcode scanners, making it easier to store and organize information.
