System Specifications

DanioVision DVOC-0041

Power Supply

• Power requirements: 24 Volt DC, 2.0 Amp (max)
• Mains adapter: Input 100–240 Volt AC, output 24 Volt DC, 3.0 Amp

Camera

• Brand, type: Basler acA1300-60gm
• Interface: Gigabit Ethernet (RJ45 connector, CAT5e or higher)
• Sensor: 1/1.8" Progressive Scan CMOS, monochrome
• Max. resolution: 1280 x 1024
• Max. frame rate: 60 fps

Lens

• Standard lens: 12 mm Megapixel, C-mount, F1.4, includes IR pass filter
• Optional lens: 8 mm Megapixel, C-mount, F1.4, includes IR pass filter

Video Performance (H x V Pixels)

• Default: 1280 x 960 at 30 fps (in combination with 12 mm lens)
• Optional:
  • 640 x 480 at 60 fps (in combination with 12 mm lens)
  • 800 x 600 at 60 fps (in combination with 8 mm lens)

Maximum frame rates as measured in 96 well plate setup.

Backlight Unit

• Type: Combined infrared (IR) and white light array
• Infrared wavelength (typical): 950 nm
• White light color temperature (typical): 5500 ºK
• White light intensity range: 0 to ±10,000 lux (measured directly at the bottom of the water basin)

White light level is controllable via USB (EthoVision XT).

According to published research, zebrafish are sensitive to infrared light, though not above 910 nm. See Shcherbakov et al. 2013, PLoS ONE (5): e64429. The IR light provided by DanioVision is therefore unlikely to affect the fish's behavior.

Note: If you set the Low Light switch to L (low), the highest light level (100%) is around 20 lux.

Note: Light intensity in DVOC-0041 can be set higher than in DVOC-0040. You may want to replicate light conditions set in DanioVision DVOC-0040 in a new experiment with DanioVision DVOC-0041. For example, if you set light intensity to 50% in DanioVision DVOC-0040, this gave 2950 lux. The equivalent percentage to set in DanioVision DVOC-0041 is (2950/5300) x 50 = approximately 28%.
