MiCAM ULTIMA

MiCAM ULTIMA, is a CMOS based ultra high speed imaging system that optimizes high speeds, high resolution, and high signal to noise ratios. It is designed to detect very small changes in fluorescent light levels of biological samples that are stained with fluorescence probes such as voltage-sensitive dyes or calcium indicators.

Main Features

Spatial Resolution
100 x 100 pixels
Image Sensor Size
10mm x 10mm
Camera Port
2
Maximum Frame Rate
10,000fps (100x100 pixels)

Applications

  • Membrane potential (voltage sensitive dye) imaging
  • Calcium imaging for in vivo brain/cardiomyocytes
  • Imaging with FRET, GCaMP, GEVI
  • Intrinsic optical signal imaging based on hemoglobin and flavoprotein autofluorescence
  • Ratiometric fluorescence imaging with 2 camera heads
  • Panoramic imaging with 2 camera heads
  • Other high speed imaging

Features

Maximum Frame Rate of 0.1msec/frame (10KHz)

Action Potential Propagation In order to record small changes in fluorescence of biological samples stained with voltage sensitive dyes, the ideal combination of high sensitivity and high speed is required. MiCAM ULTIMA, which overcomes these challenges with BrainVision's cutting-edge research and development, can detect small changes in fluorescence such as 0.1% After acquisitions, users can easily analyze signal propagation between neurons of samples such as hippocampus slices at speeds up to 10,000 frames per second and only 4 times averaging.

Real-Time Imaging of Action Potential Propagation with Single Scan

Real-Time Imaging of Action Potential Propagation with Single Scan Temporal resolution of 0.1msec/frame, spatial resolution of 100x100pixel, and dynamic range of 70db makes it possible for scientists to record neuronal activity at speeds of several millisecond/frame even without any averaging acquisition (single scan).

Huge Well Depth of Single Pixel (10Me- / 1.5Me-)

Huge Well Depth of Single Pixel Sufficient fluorescence light intensity is needed to detect small changes in fluorescence with a single sweep. MiCAM ULTIMA, which has a huge well depth (10Me- / 1.5Me-), can achieve high S/N ratios without any pixel saturation in most bright light conditions.

Completely Synchronized Dual Camera System

MiCAM ULTIMA processor has two camera ports. The ULTIMA can operate as a synchronized dual camera system by the simple addition of a slave camera and connection to the existing processor. This allows for dual-wavelength imaging or dual-staining with multiple probes such as voltage-sensitive dyes and calcium indicators.

Software with Intuitive Interface

Software with Intuitive Interface BV_Analyzer is a data analysis software and is included with all of the MiCAM systems. This software has various functions, such as wave display, 3D display, animation display, real-image display, spatial/temporal filter, high-pass/low-pass filter, AVI/TIFF/BMP/CSV file export, etc.

Characteristics of Wave Spectral Sensitivity

Characteristics of Wave Spectral Sensitivity This sensor has a wide range of spectral sensitivity between near-infra red (800-900nm) to ultraviolet (300-400nm), and has a high quantum efficiency of 50-60%. As a result, the ULTIMA is suitable for various imaging techniques with many different kinds of fluorescent dyes.

Sample data

Rat Slice Imaging at 10KHz

Action potential propagation was recorded at 0.1msec/frame. 10kHz recording allows us to identify presynaptic activity and postsynaptic activity separately.

"Mouse In Vivo Imaging using Voltage-Sensitive Dye

This data was obtained from a 2 month-old mouse that was under urethane anaesthesia (1.75 g/kg). A heating pad was used to maintain the measured body temperature of the mouse at 37°C. Two electrodes were inserted under the skin of the forearms to receive the electrocardiogram signal which was used to trigger the MiCAM ULTIMA acquisition.

Optional parts

PCI-USB Interface Converter for MiCAM ULTIMA (ULT-USB)

PCI-USB Interface Converter for MiCAM ULTIMA Previously, only the PCI card was available to connect MiCAM ULTIMA to PCs. As newer PCs were released which used newer generations of chipsets, incompatibility issues occurred between the PCI cards and the newer PCs.

To avoid these compatibility issues, the PCI-USB Converter was developed. With the PCI-USB Converter, users can select any PC to use with MiCAM ULTIMA, as long as it has a USB port. The converter is compatible with Windows XP PCs, Windows 7 (32bit and 64bit) PCs, Windows 10 (64bit) PCs and Windows 11 PCs.
