Design and specifications
- Collection Optics: Primary Detection Dichroic: 60 x 40 x 1
- : Collection lens diameter: 45 mm
- : Maximum collection angle: ~±8° assuming 20mm objective back aperture
- : IR Blocking Filter: 680nm Shortpass 50mm Ø
- Emission Filters: Emission filter: 32mm Ø - one for each detector
- : Short wavelength perpendicular to the incident light, longer wavelength on the incident direction
- : Blocking filter: 32mm Ø for stimulation wavelength
- Photomultiplier Tubes: Two locally mounted detectors of the same type: GaAsP protected photomultiplier tube (H10770PA-40) or GaAsP photomultiplier tube with gating function (H11706P-40)
- : Signal output Connector: SMA
- : Gate input connector (gated GaAsP only): BNC
- Protection Circuitry: Protected GaASP: Integrated protection circuitry to trip PMT when overload detected
- : Gated GaAsP: Voltage gating functionality to avoid overload situations
- : All systems: Ambient light detector
- Objective and Nosepiece Compatibility: Objectives: M32, M27, M25, RMS threaded objectives (<20mm back aperture)
- : Nosepieces: Ships with single objective changer with 2 locking sliders
- : Compatible with: WI-SRE3 adapter (RMS only) or standard/DIC objective sliders
- Preamplifier Bandwidth: Options include: 20 MHz (resonant system), 1 MHz (galvo), or variable bandwidth all with low noise linear power supply
- Output Connection: BNC
- PMT Voltage Control: Manual or Software Control
- PMT Protection: Integrated protection circuitry in H10771P-40 only. For all PMT options, a remote ambient light sensor is used
