HAWAII-2RG™

Product catalog summary

Overview: The HAWAII-2RG™ (H2RG) is a high-performance readout integrated circuit designed for visible and infrared astronomy applications in both ground-based and space telescopes. It features a large 2048×2048 pixel array with an 18 µm pixel pitch.

Specifications:

Pixel Array: 2048×2048 pixels with 18 µm pixel size.
Compatibility: Works with Teledyne Imaging Sensors' HgCdTe infrared and silicon PIN HyViSI™ visible detectors, covering spectral bands from soft X-ray to 5.5 µm.
Substrate-Removed HgCdTe: Enhances J-band quantum efficiency, allows visible spectrum response, and eliminates substrate-related issues like fluorescence and fringing.
Noise Rejection: Includes reference rows and columns for common-mode noise rejection.
Guide Window Output: Supports windowing with simultaneous full array data acquisition, programmable for up to 5 MHz pixel rate.
Output Flexibility: Selectable outputs (1, 4, or 32) and scan directions for flexible data acquisition.
Readout Rates: Full-frame readout rates range from less than 0.1 Hz to 80 Hz.
Modularity: 4-side-buttable design for assembling large mosaics, such as 4096×4096 arrays.
Compatibility: Fully compatible with TIS SIDECAR™ ASIC Focal Plane Electronics.

Performance Parameters:

Quantum Efficiency (QE): Varies by wavelength, with goals of ≥ 70% at 800 nm and 1,000 nm, and ≥ 80% at 1,230 nm and 1,500 nm.
Dark Current: Median dark current is ≤ 0.05 e-/s, with a goal of ≤ 0.01 e-/s.
Readout Noise: Median readout noise is ≤ 30 e- at 100 kHz pixel readout rate, with goals of ≤ 15 e-.
Well Capacity: ≥ 80,000 e- at 0.25 V bias, with a goal of ≥ 100,000 e-.
Crosstalk: ≤ 2%, with a goal of ≤ 1%.
Operability: ≥ 95%, with a goal of ≥ 99%.
Flatness and Planarity: SCA flatness ≤ 30 µm and planarity ≤ 50 µm, with goals of ≤ 10 µm and ≤ 25 µm respectively.
