Ultra-fast Imaging

NeuroPlex II

The NeuroPlex II from RedShirtImaging uses a photodiode array for fast imaging at limited resolution but very high speed - 24 x 24 pixels and 1600 frames/sec. It is suitable for relatively high fluorescence levels, and has a very wide dynamic range (>17 bits).

• Uses the WuTech H-469IV photodiode array system (originally developed by Yale University School of Medicine)
• Simultaneous optical and 8 channels of electrical recording
• Optical coupler to reduce objective image to the size of the CCD chip
• Comprehensive, user-friendly software designed for neurobiologists, physiologists and biophysicists
• Computer control of shutter and stimulator

NeuroCCD

The NeuroCCD from RedShirtImaging is a low dark-noise, cooled CCD imaging system suitable for low fluorescent light levels. It uses the Marconi CCD39-01 CCD chip and achieves 2000 frames/second at 80 x 80 pixels.

• 80 x 80 pixels
• Full-frame, frame rate: 2,000 Hz
• 3x3-binning, frame rate: 5,000 Hz
• Back-illuminated for high quantum efficiency (80% from 400-600nm)
• Cooled CCD: for low dark noise
• Readout Noise: 2,000 Hz: 26 e- ; 1,000 Hz: 9 e- ; 125 Hz: 4 e- ; 40 Hz: 3 e-
• Large well size: 300,000 e-
• Digitization: 14 bits standard; 16-bits optional (slower frame rate)
• No fan - vibration free
• Frame transfer to minimize smear: transfer time 7 micro-seconds
