MKC-835S
3CMOS High-Sensitivity 4K Camera
The MKC-835S is a medical-grade 4K camera that combines ultra-high-definition 4K (3840 × 2160) imaging with exceptional sensitivity of F13 at 2000 lx*1, achieved through proprietary algorithms and advanced image processing technologies.
Its high-resolution and high-sensitivity imaging capabilities provide reliable support for a wide range of medical procedures and clinical applications.
*1 Standard settings (Line Mix OFF).
Superior 4K Image Quality
Featuring a 4K (3840 x 2160) digital processing system, the MKC-835S achieves four times the resolution of conventional Full HD (1920 x 1080) systems. A horizontal resolution of 1600 TV lines and an S/N ratio of 63 dB ensure exceptional image quality.
High Sensitivity
Equipped with 1/2.8-inch CMOS sensors, the MKC-835S camera system delivers remarkable sensitivity at F13/2000lx * and an impressive S/N ratio of 63 dB. This enables you to capture exceptionally clear and bright images, even in low-light surgical conditions. Sensitivity can be further enhanced using Hyper Gain, Line Mix, and Pixel Mix functions.

Flexibility for Every Clinical Environment
The camera cable can be separated into a 5m section on the camera head side and a 10m section on the CCU side, allowing safe and efficient movement and installation of the surgical microscope and monitor cart. This camera system is also compatible with ceiling-mounted surgical microscopes. In addition, antibacterial coatings applied to both the camera head and CCU help suppress bacterial growth.
Compact Design
Small and lightweight camera head. Designed for installation on surgical microscopes with limited space, without compromising operability.
Image Enhancement Functions
The MKC-835S offers advanced image enhancement functions that harness the state-of-the-art Ikegami video processing algorithm to achieve optimal video images across diverse procedures and specialties.
All Four Functions from the Previous Model Included as Standard
16-axis Color Correction・Chroma Correction・Gamma Correction・Flare Correction
Two New Standard Functions
Beyond the standard image enhancement functions, the MKC-835S introduces additional functions that elevate image enhancement to a higher level.
Picture Effect
A distinct image processing technique is utilized to improve the visibility of the subject.
- Contrast Correction∗
Images become more viewer-friendly thanks to a contrast correction function that compresses the high-brightness area, elongates darker portions, and minimizes color distortion.

Contrast Correction ON
- Blood Vessels Highlight∗
Highlighting the patterns of blood vessels and the surface layer of mucous membranes enhances visual perception of the image.

Scene File
Streamline your operations with a single touch.Scene files provide the capability to preset up to four camera settings, whether they are frequently used or tailored to specific procedures, ready to be activated with a simple button press.Additionally, scene file settings can be stored and loaded via a USB flash drive for added convenience.
Fluorescein Mode
Featuring a fluorescein mode, the MKC-835S empowers the clear capture of fluorescent spots during ophthalmological slit lamp fluorescein testing. This function also allows the reduction of excitation light color and offers the convenience of color tone adjustments during fluorescein mode, with easy switching options assignable to a function button or through a foot switch.
