Integration and compatibility
Use these checks to connect DField-VS-A4 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Spectral response
- Peak quantum efficiency: 95% at 800 nm
- Responsivity varies strongly across the stated band. Read the figure at your own wavelength rather than at the peak the headline range implies.
- Active area
- Active pixels: 2048 × 264 · Pixel size: 15 × 15 µm
- Active area sets both the alignment tolerance and, through capacitance, the achievable bandwidth. A larger element is easier to hit and slower to read.
