in automated test functions such as pixel noise, dark current, wavelength calibration and linearity
measurements greatly simplify operation. All of the data can be saved as a text file for data analysis using
EXCEL spreadsheet.
The HC230, HC231 and HC236 series are based on a back thinned (BT) full frame transfer CCD having
90% quantum efficiency (QE) at 600nm. Each sensor has a 24um square pixel. The pixel format ranges
from 532x64, upto a 1044x256 matrix. These scientific grade imagers operate in the MPP mode greatly
reducing dark current generation, aditional reduction is achieved using a built in thermo-electric cooler.
Customized LabVIEW drivers control the readout in either area scanning mode (2D) or full line binning
mode (1D).
A front illuminated (FI) version having extremely low dark current (15 e-/pixel/second @ -100C) is the
HC232 series. Matching the pixel size and format with the BT-CCD family. The HC232 series is well
suited for visible to near infared spectrometery application.
For higher light levels users prefer the HC233 series. These self scaning photodiode arrays have a 50pC
saturation charge making it ideal for absorption measurements. The pixel height is 2500um while the
pitch rangeing from 25um too 50um.
Telecommunications monitoring DWDM signals will benefit from the HC234 series. The pixel pitch is
25um or 50um, peak response is centered at 1550nm. Pixel counts from 256/50um upto a 512/25um.
