General | The tissue/smear must be mounted with a coverslip, glass or tape. | |||
Standard | 1-inch x 3-inch (2.54 cm x 7.62 cm) slides. Compatiable with ISO 8037/1. | |||
Thickness | 0.9 mm ~ 1.1 mm, excluding coverslip | |||
Special Requirement | The coverslip and attached label must remain fully within the microscope slide perimeter, secured with complete adhesive contact. All surfaces shall lie flat without edge separation. The slide exterior must maintain dryness with no fluid leakage from the specimen zone. | |||
Maximum Tissue/Smear Thickness | Optimized for tissue thickness of 3-5 μm (including mounting media) | |||
Coverslips Accepted | The coverslip/label assembly (0.17 mm nominal thickness, standard borosilicate glass or cellulose tri-acetate film) must maintain full edge registration with the microscope slide substrate through continuous adhesive bonding. All interfacial surfaces shall exhibit co-planar adhesion integrity with zero delamination, while the external slide surfaces remain contamination-free from residual fluids or specimen migration. | |||
Label Area (W x L) | 25 mm x 25 mm | |||
Label Special Requirement | Adhesive labels must maintain non-protrusive margins within slide boundaries and demonstrate full-surface lamination to the coverslip interface plane (upper slide surface). Prohibited from substrate attachment on the specimen observation surface (lower slide plane), all labeling components shall exhibit edge-to-edge planar adhesion without delamination defects. | |||

Fluorescence Scanning Features
KFBIO Digital Pathology Slide Scanners (fluorescence) have excellent performance in the accuracy of movement, focus, and image processing, and its accurate whole slide imaging not only meets the requirements of digital slide viewing and operation but is also suitable for AI-assisted image analysis.


Excellent Cross Color Suppression Design
Independent LED light source avoids cross color. High contrast, high brightness, no drift, and no cross color make it more suitable for specific fluorescence channels. Equipped with CHROMA filter narrowband filter, the minimum spectral band resolution reaches 10nm, which can efficiently separates different fluorescence channels to achieve large information density without affecting the quality of data.
High-Sensitivity Cooled Scientific CMOS Camera
Dhyana 400D high-sensitivity refrigeration scientific CMOS camera is equipped, low signal-to-noise ratio and high resolution, with a new 1.2 inch surface array scientific CMOS chip. The quantum efficiency at 600 nm is up to 80%. 6.5 μm pixel size and 2*2 pixel binning function realized by FPGA, suitable for low-light detection and imaging. The Dhyana 400D has excellent performance, with only 2 electrons of readout noise. The browsing speed is up to 35 frames/s at 4 megapixels. And the data transmission speed is up to 5Gb/s to provide strong support for users’ work.
Large Field of View, Long Work Life
The 26.5mm field of view keeps the image flat, decreasing shooting and exposure time. The LED light source ensures more than 20,000 hours work, long-lasting and simple to maintain. Non-contact Hall switches are used to power the light source, and wireless charging technology is introduced to save wiring, which boosts system stability.
Image Processing Algorithm
The fluorescence image stitching algorithm based on high-precision direct position feedback is used to splice images to obtain seamless whole-slide images and improve browsing experience. Pupil function of visual image enhancement algorithm is applied, no need to correct slides. The optical field information is efficiently estimated based on the limited excitation light information. When the light field information does not change with the increase of new sample, the light field information must be the right one for the set of optical path, and the light field can be calibrated based on this information.
